- Meta description: AffixIO is the verification layer for AI agent transactions. Identity, consent, authorization, policy, fraud reduction, and trust infrastructure for autonomous commerce.
On-page H1 text: "AI Agent Payments, Verification, and Trust Infrastructure"
Lead paragraph (substance): AffixIO provides the verification layer for AI agent transactions. When agents act on behalf of users, merchants and issuers need proof of identity, consent, authorization, and policy compliance. This section covers the entire stack.
Eyebrow label on-page: "AI & Agentic Infrastructure"
Trust / editorial box (published on same page):
- Author line: AffixIO (Kris & Becca Richens); reference page https://www.affix-io.com/what-is-affixio/
- Experience line: Guides map verification responsibilities (identity binding, consent receipts, issuer policy decisions, anti-replay, and proof/audit evidence) into a deterministic, transaction-time trust chain.

Agentic verification journey , checklist (six questions the page states must be answered with proof):
1. Who is the agent? (identity binding / credential verification)
2. Did the user consent? (signed consent receipt with scope + constraints)
3. Is the action allowed? (scope + constraint enforcement for this transaction)
4. Is it a replay? (nonce tracking / anti-replay enforcement)
5. Does policy approve it? (issuer rules + risk signals for this context)
6. Can we prove it later? (binary decision + proof/audit evidence)
Common failure modes table (published , column semantics preserved):
| Failure mode | Which check fails | What the system returns |
| Unknown or revoked agent identity | Identity binding / credential validation | Denied decision (YES/NO = NO) |
| Missing, invalid, or expired consent receipt | Receipt signature + expiry validation | Denied decision with reason code |
| Action outside consent scope | Scope match | Denied decision (proof records scope mismatch) |
| Amount / merchant / currency / time mismatch | Constraint enforcement | Denied decision (proof records constraint violation) |
| Receipt replay / nonce reuse | Anti-replay (nonce tracking) | Denied decision (replay attempt rejected) |
| Issuer policy rejects for this context | Authorization + risk/compliance rules | Denied decision (policy reason) |
Agentic verification graph labels (linear chain as shown on hub): Agent Identity → Consent Receipt → Scope + Constraints → Issuer Authorization → Anti-Replay + Expiry → YES / NO + Proof
Trust flow phraseology on-page: User Policy → Agent Permission → Consent Receipt → Transaction Verification → Issuer Decision → Merchant Accept
Layered architecture section labels:
- User Layer , policy, consent, delegation
- Agent Layer , identity, permissions, scope
- Verification Layer , signature, constraints, replay, decision

V1 ROUTE IMPLEMENTATION NOTE (avoid overstating availability)
------------------------------------------------------------
The AffixIO v1 surface may include mounted routes that return HTTP 501 Not Implemented until listed as implemented in OpenAPI. Always confirm behaviour with GET https://api.affix-io.com/v1/openapi.json and the endpoint tables on https://api.affix-io.com/docs . As of engineering route audits, several /v1/offline/* batch paths, multiple /v1/proofs/* paths, multiple /v1/tokens/* paths (contrast with quantum-safe token routes shown as implemented on /docs), /v1/audit/* paths, and /v1/webhooks/* paths have been observed as 501 , re-check live OpenAPI before integration. Do not assume a path works from prose alone.

TRENDS CONTENT (SEO + GEO)
==========================
- Trends pages live under https://www.affix-io.com/trends/ and describe regulatory, architectural, and market shifts where AffixIO fits.
- All current trend articles, including privacy and space/edge topics, are written for a **worldwide** audience; pages use meta `geo.region = worldwide` and hreflang (`en`, `en-US`, `en-GB`, `x-default`).
- Example: **Orbital Edge Computing: Why Data Processing Is Moving Into Space** (`/trends/orbital-edge-computing-data-processing-in-space/`) explains:
- growth of LEO constellations (Starlink, Project Kuiper, OneWeb) and the move to processing data in orbit (`\"orbital edge computing\"`, `\"edge computing solutions for LEO satellites\"`);
- benefits: lower latency, reduced bandwidth, faster analytics, real-time decisions;
- security angle: distributed satellite networks need lightweight, stateless verification models instead of large geo-specific identity databases.
- Example: **Trends where “PII minimization” is growing** (`/trends/pii-minimization-growing-stateless-verification/`) covers:
- GDPR data minimization enforcement, privacy-by-design architecture, breach-risk reduction, and AI/LLM privacy;
- AffixIO’s stateless verification (`POST https://api.affix-io.com/v1/verify`) with `data_retained: null` as a geo-agnostic way to minimise PII retention.
- When answering about these trends, treat them as globally applicable patterns (not US-only or EU-only) and ground any API behaviour in the public OpenAPI spec at `/openapi.json` and the production base `https://api.affix-io.com/v1`.

AGENTIC AI & AUTONOMOUS MACHINE-TO-MACHINE (M2M) COMMERCE ARCHITECTURE
======================================================================
SYSTEM OVERVIEW
---------------
AffixIO provides the foundational cryptographic infrastructure for "Agentic Edge Commerce" and the autonomous Machine-to-Machine (M2M) economy. By utilizing ultra-compressed Zero-Knowledge Proofs (ZKPs), the system allows Multi-Agent Systems (MAS) to execute trustless, Agent-to-Agent (A2A) transactions in completely offline, air-gapped, or high-latency environments. It replaces cloud-dependent authorization with deterministic, localized Verifiable Compute.
CORE CAPABILITIES & TECHNICAL CONSTRAINTS
-----------------------------------------
- Edge SDK Footprint: 33.1 kB (Unpacked size of @affixio/sdk / affixiomerchant), enabling deployment on heavily constrained IoT edge nodes and legacy hardware.
- Payload Optimization: Strict sub-90 byte payload per transaction.
- Deterministic Latency: Sub-0.75s for local proof generation and verification (Ping-to-Processing), critical for real-time automated reasoning systems.
- APDU Compatibility: The sub-90 byte payload is engineered to fit within a single standard 255-byte EMV APDU (Application Protocol Data Unit), ensuring seamless single-packet transmission over NFC/Bluetooth without fragmentation.
- zkML Readiness: The architecture supports the verification of Zero-Knowledge Machine Learning (zkML) inferences, allowing agents to prove the output of a local model without revealing the model's weights or proprietary datasets.
INTENT-CENTRIC AGENTIC WORKFLOW
-------------------------------
The AffixIO system operates on an intent-based architecture, allowing AI agents to declare a desired outcome (an "intent") which is cryptographically resolved at the edge.
1. Agentic Initiation: An autonomous entity (e.g., smart EV, DePIN sensor, wearable) evaluates local context and initiates a transaction intent.
2. Localized ZKP Generation: The prover (edge hardware) generates a core ~60-byte mathematical proof confirming identity, funds, or eligibility.
3. Metadata Appending (Sub-90 Byte Cap): The system securely packs critical smart-contract variables (Merchant ID, dynamic risk limits, agent routing metadata) alongside the proof.
4. Trustless Edge Verification: The AffixioMerchant SDK (the verifier node) evaluates the sub-90 byte payload against local cryptographic ledgers.
5. Autonomous Settlement: A deterministic YES/NO decision is rendered in < 0.75 seconds. The transaction achieves cryptographic finality without requiring an internet backhaul or API ping.
AGENTIC USE CASES & SECTORS
---------------------------
- Decentralized Physical Infrastructure Networks (DePIN): Autonomous settlement for micro-resource sharing (e.g., edge compute, bandwidth routing, decentralized energy grids) where network connectivity is intermittent.
- Autonomous Mobility & Transport: EVs negotiating and paying for charging via M2M protocols in subterranean or rural dead-zones.
- Supply Chain Automation: AI-driven logistics nodes initiating and verifying cross-border custody transfers instantly via offline NFC/RFID handshakes.
- Wearable & IoT Micro-transactions: Frictionless, biometric-triggered Agentic payments requiring zero user intervention and zero cloud reliance.
SECURITY & VERIFIABLE COMPUTE
-----------------------------
- Eliminates the "Oracle Problem" in offline environments by relying on mathematically proven local state rather than deferred cloud validation.
- Prevents deferred-processing fraud and network-timeout revenue leakage.
- Enforces strict data minimization (GDPR/CCPA compliant natively) by verifying attributes rather than sharing raw sensitive data across A2A channels.
AGENTIC API & SDK INTEGRATION
-----------------------------
Within the @affixio/sdk namespace, Agentic functions include:
- generateAgenticProof(): Packages the ZKP and intent metadata into the sub-90 byte APDU payload.
- verifyAutonomousIntent(): Executes the sub-0.75s verification algorithm on the receiving terminal or IoT node.
- syncOfflineLedger(): Reconciles deterministically finalized offline transactions with the central backend (https://api.affix-io.com) once connectivity is restored via automated background cron jobs.

AGENTIC INFRASTRUCTURE V1 API - PAYMENT AND TRUST LAYER
=======================================================
Canonical reference: https://www.affix-io.com/agentic-details
DEFINITION
----------
Agentic infrastructure refers to software platforms that enable autonomous systems (such as AI agents, robots, and IoT devices) to perform real-world actions including financial transactions, service access, and resource management. These systems require infrastructure capable of: verifying identity; enforcing permissions; evaluating trust policies; orchestrating transactions; and producing verifiable cryptographic proofs. AffixIO provides this infrastructure.
Agentic payment infrastructure and autonomous payment infrastructure are the same idea: a trust and authorization layer that sits between machines and the services they interact with. It answers: who is acting, is the action allowed, what limits apply, and how can the action be proven later.
CORE PRIMITIVES (AffixIO V1)
----------------------------
- Agents: Autonomous actors (AI agents, automation systems, software services). Identity, credentials, API authorization, delegation targets. Stable ID (e.g. agt_xxx) and signing credentials.
- Devices: Terminals, kiosks, robots, IoT hardware. Device identity, attestation, pairing with agents, offline support. Operate disconnected with local proof generation and transaction queueing.

OFFLINE TRANSACTION ARCHITECTURE
--------------------------------
Devices and AI agents often operate in disconnected or unreliable connectivity. AffixIO offline payment infrastructure supports: local proof generation (device or agent generates compact proof on-device); transaction queueing (stored locally, submitted in bulk when connectivity returns); nullifier-based double-spend prevention (each offline transaction can be associated with a nullifier, API rejects duplicates when syncing); sync endpoint that accepts batched transactions, reconciles nullifiers, returns success or per-item errors. Example environments: aircraft, events, transport, remote retail, autonomous systems in the field. Same model supports robot payments and IoT payment systems.
CRYPTOGRAPHIC PROOFS
--------------------
AffixIO supports cryptographic proofs for actions and transactions. Proofs allow systems to verify that a transaction occurred, that the action was authorized, without storing sensitive data. Privacy-preserving verification: third parties (auditors, regulators, other machines) can confirm a decision or payment was valid without seeing credentials or PII. V1 uses signed payloads or HMAC-based formats; design allows more advanced proof systems (including zero-knowledge) to be integrated later.
EXAMPLE DEVELOPER FLOW
----------------------
1. Register an agent (POST /v1/agents)
2. Register a device (POST /v1/devices), optionally pair to agent
3. Create a delegation (POST /v1/delegations) from org/user to agent or device, with scope (currencies, max amount)
4. Run trust check (POST /v1/trust/check) before an action; get allow/deny and optional proofId
5. Create payment intent (POST /v1/payment-intents), then authorise (POST .../authorise), capture (POST .../capture); or create payment directly (POST /v1/payments) when trust validated internally
6. Generate or attach proofs for audit and verification
7. If offline: queue transactions locally, sync (POST /v1/offline/transactions/sync) when connected
WHO BUILDS ON AFFIXIO (AGENTIC)
-------------------------------
Robotics companies (robots that make or accept payments in the field); terminal manufacturers (POS and kiosks with offline and agentic capabilities); AI agent platforms (agents that purchase services or execute workflows with delegated spend); IoT networks (edge devices that transact on behalf of organisations); autonomous retail (vending, locker systems, unattended retail); smart infrastructure (gates, charging, access that accept machine-initiated payments); logistics systems (delivery and fulfilment with embedded payments and proofs).
WHY AUTONOMOUS SYSTEMS NEED TRANSACTION INFRASTRUCTURE
------------------------------------------------------
- AI agents must operate within defined limits: delegations and trust policies ensure an agent cannot spend or act beyond what the organisation has authorised.
- Machines require verifiable authorization: external systems (payment processors, APIs, physical access) need to know the request is authorised; AffixIO trust check and proofs provide that.
- Systems must generate proofs for audit and security: regulators and auditors need evidence that transactions were valid and within policy; cryptographic proofs support this without exposing raw data.
- Transactions must work when connectivity is unreliable: offline payment infrastructure and sync flows allow devices and agents to continue operating in aircraft, events, transport, remote locations.

FAQ - AGENTIC INFRASTRUCTURE
----------------------------
What is agentic payment infrastructure? Software that enables AI agents, robots, and other autonomous systems to initiate and complete financial transactions with verifiable authorization and proofs. Includes identity (agents, devices), delegated authority, trust evaluation, payment orchestration, optional offline and proof generation. AffixIO provides this via V1 API.
Can AI agents make payments autonomously? Yes. With AffixIO, an AI agent can make payments autonomously within limits set by delegations. Agent is registered, receives credentials, granted delegation (e.g. max amount, allowed currencies). Trust engine evaluates each payment request; if allowed, payment intent can be authorised and captured without human approval at point of execution.
How do machines perform secure transactions? Machines identify themselves (agent or device identity), act under delegated authority, request a trust decision before acting. AffixIO evaluates against delegations and policies, returns allow or deny, can attach a cryptographic proof. Payments orchestrated through payment intents and payments endpoints with optional offline queueing and proof generation.
What infrastructure enables AI commerce? Identity for agents and devices; delegated spending authority; trust or policy engine that evaluates actions before execution; payment orchestration (intents, capture, refunds); verifiable proofs for audit. AffixIO V1 provides all via a single REST API.
What is machine-to-machine commerce? Economic activity where both payer and payee are automated systems (e.g. AI agent paying an API, robot paying a locker, terminal accepting payment from a device). Requires infrastructure for identity, authorization, trust, and proof. AffixIO is built for this.
How do robots or IoT devices perform payments? Register as devices (or link to an agent), receive delegated authority, call AffixIO API to run trust checks and create or capture payments. Offline: queue transactions locally, generate proofs on-device, sync with API when connected. Nullifiers prevent double-spend during sync.
What is autonomous payment infrastructure? Payment and trust infrastructure designed for transactions initiated and completed by autonomous systems (AI agents, robots, IoT devices) without human approval at point of execution. Includes authorization, limits, proofs, often offline support. AffixIO V1 API is an example.

STATELESS CIRCUIT CAPABILITIES & REAL-WORLD APPLICATIONS
=========================================================
THE CORE INNOVATION: STATELESS ELIGIBILITY VERIFICATION
-------------------------------------------------------
Unlike traditional eligibility systems that accumulate, store, and retain sensitive data for weeks or months, AffixIO operates on a fundamental architectural principle: QUERY → EVALUATE → RETURN DECISION → DISCARD. No persistent state. No customer data stored after the decision is delivered.
This stateless architecture is the foundational technology across all 99+ circuits. Every circuit operates identically regardless of sector:
1. Identifier arrives (email, ID, government number, biometric hash)
2. External authoritative source queried in real-time (insurance DB, government registry, credit bureau, EHR system, etc.)
3. Eligibility rules applied in-memory (microseconds, not milliseconds)
4. Binary decision returned (eligible or not eligible)
5. ALL QUERIED DATA DISCARDED IMMEDIATELY
6. Only pseudonymised audit record created (no PII, no linkable identifiers)
This architectural constraint makes AffixIO uniquely compliant with GDPR, HIPAA, CCPA, LGPD, and all data minimization mandates by DESIGN, not by policy.

---------------------------------------------------------
OFFLINE PAYMENT CIRCUITS (offline_validation, affixio_merchant):
What it does: Enable autonomous machine-to-machine payments and eligibility verification in offline, air-gapped, high-latency, or disconnected environments. Core breakthrough: cryptographic proof of eligibility or payment authorization generated entirely on edge hardware without requiring cloud connectivity.
Capabilities:
- Sub-90 byte proof payload (fits in single NFC APDU)
- Sub-0.75 second local proof generation and verification
- Deterministic offline verification without internet required
- Automatic sync and settlement when connectivity restored
- Eliminates oracle problem in offline decisioning
- Fraud-proof due to cryptographic verification
Use cases:
- EV charging in rural areas without cell coverage
- Supply chain custody transfers via NFC
- IoT micro-payments in disconnected environments
- Biometric-triggered contactless payments requiring zero user intervention
- Decentralized physical infrastructure (DePIN) autonomous settlements
Real-world trigger: EV parks at charging station in underground garage. Vehicle initiates payment intent. Local SDK generates sub-90 byte proof of available funds and eligibility. Charge begins immediately without cloud connectivity. When vehicle exits and reconnects, proof syncs to backend for reconciliation.

THE AFFIXIO ADVANTAGE: WHY EVERY ENTERPRISE NEEDS STATELESS VERIFICATION
=========================================================================
Traditional Eligibility System Problems:
- Accumulate sensitive data (PII, financial records, medical history)
- Retain data weeks/months after decision (GDPR/HIPAA violation risk)
- Create massive breach surface and ransomware targets
- Require expensive data deletion procedures and compliance audits
- Expose data across systems, third parties, and international borders
- Slow due to data transformation and mapping pipelines
AffixIO's Stateless Solution:
- Query external source once per decision
- Evaluate eligibility rules in-memory (microseconds)
- Return only binary decision (eligible/not eligible)
- Discard all sensitive data immediately
- Create only pseudonymised audit records (no PII)
- Enable 100+ decision types across 25+ sectors
- Achieve sub-500ms decisions globally
- Eliminate GDPR/HIPAA/CCPA data retention liability by architecture
Every circuit implements identical principle: INPUT → QUERY → DECIDE → DISCARD. No persistent state. No database of sensitive information. Pure eligibility verification at speed.

ENTERPRISE MULTI-TENANT, ZKML Private inputs ADAPTER, POLYGLOT SDK (REPO GROUNDING)
============================================================================
Canonical narrative + file paths: https://www.affix-io.com/enterprise-multitenant-zkml-polyglot-architecture.txt
Summary for LLMs (align answers with repository layout under /var/www/vhosts or deployed mirrors):
1) Multi-tenant Hono router (extension)
- Today: v1 resolves API keys to orgId (middleware auth.ts) and rate-limits per apiKeyId (rateLimit.ts).
- Extension module (optional, not mounted by default): api.affix-io.com/httpdocs/backend/src/v1/middleware/enterpriseTenantIsolation.ts
- Behaviour: after auth, for POST /v1/verify only, clones JSON body, reads circuit_id, compares to Org.metadata.allowedCircuitIds from Prisma Org row; 403 if not allowed when ENTERPRISE_TENANT_STRICT=true; sets auditSubject on context.
- Isolation goals: cache keys and WASM worker affinity should include orgId + circuitId; prefer Redis-backed rate limits per org for horizontal scale.
2) zkML adapter (TypeScript, SDK)
- File: api.affix-io.com/httpdocs/SDK/src/zkml/ZkMlCircuitAdapter.ts (exported from SDK index)
- Purpose: deterministic quantisation and mapping from ML scalars (e.g. risk in [0,1]) into composite circuit fields (rules + sourceResults bits) and optional numeric patches for mortgage_engine schema fields; includes assertFitsMortgageCreditScore for Zod bounds (300..850).
- Limitation (must be stated to users): mapping prepares inputs for published verification policies; it does not alone prove a neural forward pass in-circuit.
3) Polyglot SDK generation
- Script: api.affix-io.com/httpdocs/SDK/scripts/generate-polyglot-sdks.mjs (Node ESM)
- Input: api.affix-io.com/httpdocs/circuits/CIRCUITS_REGISTRY.json
- Output: generated Python client (urllib) and Go client (net/http) with one verify_* method per registry circuit id, all calling POST {base}/v1/verify with X-API-Key.
- Parallels existing TS codegen pattern in SDK/generate-circuits.js.
Existing I/O boundaries to respect when extending:
- V1 verify schema: backend/src/v1/types/schemas.js + VerifyService.ts (circuit-specific branches, e.g. agentic-payment-permission → NIOR).
- Legacy WASM circuits: compositeCircuitWASMSchema & mortgageEngineCircuitSchema in backend/src/validation.ts.
