Definition

What agentic systems means

In plain terms: an agent or workflow engine requests a verification decision. AffixIO returns a machine-readable signal. The signal can confirm eligibility, permission, or trust state. The agent does not need full identity or raw PII. The verification layer stays privacy-first and stateless.

Context

Why machine-to-machine verification matters

Autonomous systems need clear trust signals. Agents cannot rely on vague human workflows. Many systems overshare data. Existing flows often create unnecessary compliance scope. Machine decisions need binary, auditable, low-friction verification. AffixIO provides that verification layer.

How it works

How AffixIO agentic infrastructure works

Agent or workflow engine sends a verification request. AffixIO policy, proof, and stateless decision layer produce a cryptographic verification output. The agent uses that output for downstream action. The output can be used to approve a machine action, unlock a workflow step, allow a purchase path, confirm access rights, or confirm eligibility without exposing identity.

01 / REQUEST

🤖

Agent initiates verification

An autonomous agent or agentic pipeline calls the AffixIO API with a verification context. No credentials, no PII, no session state required from the agent side.

02 / PROOF

🔐

ZK proof generated

AffixIO processes the eligibility check using zero-knowledge proof construction. The underlying data never leaves the secure enclave. A signed binary proof token is returned.

03 / ACT

⚡

Agent acts on binary signal

The agent receives a cryptographically verified YES or NO. It can proceed, gate, route, or escalate, with a tamper-proof audit trail attached to every decision.

Capabilities

Key capabilities

Machine-readable verification signals

Agents receive binary or structured signals they can act on without parsing human-facing content.

Stateless verification

No session or server-side state. Each request is self-contained and independently verifiable.

Privacy-preserving responses

Responses confirm eligibility or permission without exposing underlying identity or PII.

PCI-DSS zero scope design

Verification layer operates on signals, not card data, keeping the AffixIO layer outside PCI scope.

API-first integration

RESTful API and documented contracts for agents, orchestrators, and internal systems.

Proof-backed decisioning

Decisions are backed by cryptographic proof suitable for audit and downstream trust.

Low-data architecture

Only the minimum data required for the verification is used; no unnecessary retention.

Cross-sector deployment

Usable across payments, access, eligibility, ticketing, and machine-led decision environments.

Architecture

Built for agentic pipelines

Designed from the ground up for machine-initiated, machine-consumed verification flows.

🔒

Stateless by design

No session state maintained between requests. Each M2M call is fully self-contained. Agents scale horizontally without verification bottlenecks.

🌐

Offline-capable proof tokens

Cryptographically signed tokens with bounded validity windows. Agents in air-gapped or intermittently connected environments verify locally without a live API call.

⚖️

PCI-DSS zero scope

Payment agents never touch card data. AffixIO sits entirely outside the cardholder data environment. No PCI-DSS scope expansion for your agentic infrastructure.

📋

Tamper-proof audit trail

Every agent decision is backed by a pseudonymised, cryptographically linked log entry. Full audit compliance without storing personal data.

Use cases

Where agentic verification applies

Agentic payments approval logic, autonomous procurement controls, machine-led access checks, eligibility checks for benefits or regulated flows, ticketing and event entry automation, merchant and terminal workflow automation, and internal enterprise orchestration. For each: the agent sends a verification request, AffixIO returns a machine-readable result, and privacy and statelessness keep scope and compliance minimal.

💳

Agentic payment authorisation

AI agents autonomously authorise high-value payments against verified merchant and customer eligibility signals. No human approval loop required for known-good patterns.

🏥

Healthcare agent workflows

Clinical AI agents verify patient eligibility for treatments, prescriptions, and referral pathways without processing raw PHI in the agent context.

🏦

Financial compliance agents

KYC, AML, and sanctions screening pushed into autonomous compliance pipelines. Agents gate onboarding and transactions based on real-time verified status.

🤝

Multi-agent orchestration

Supervisor agents delegate sub-tasks to specialist agents, with AffixIO providing the trust layer between them. Each agent handoff is cryptographically verified.

🔓

Access control pipelines

Agents managing physical or digital access gates query AffixIO for real-time eligibility. Offline-capable for venue, facility, and restricted-content control.

📦

Supply chain verification

Autonomous procurement and logistics agents verify supplier credentials, compliance status, and delivery eligibility without manual checks at each step.

Compliance

Regulatory-grade for agentic AI

Privacy regulations don't pause for autonomous systems. AffixIO ensures your agentic pipelines are compliant by architecture.

GDPR: no personal data in agent context HIPAA: no PHI transmitted to agents CCPA: zero data sale, right to deletion supported PCI-DSS: zero scope expansion SOC 2: pseudonymised audit trails LGPD: Brazilian market compliant

Privacy

Why privacy-preserving matters

Agents do not need raw identity data to make verified decisions. Systems should minimise exposure. Machine workflows should receive only the signal required to proceed. Reducing unnecessary data reduces operational and compliance burden. AffixIO is designed so the verification layer never receives or stores PII; see our privacy policy for full details.

Compliance

PCI-DSS zero scope

AffixIO does not store PAN. AffixIO does not act as the money mover. The system is designed to operate with verification signals rather than raw card data. This supports a PCI-DSS zero scope architecture for the AffixIO layer. Your payment flows remain with your acquirer or processor; we provide the verification and proof layer only.

Architecture

Stateless ZK backing

Verification is backed by stateless architecture. Proof logic can confirm a condition without oversharing underlying data. Outputs are suitable for machine decisioning. The system design supports privacy, auditability, and portability. For technical details, see the technical architecture.

Integration

How developers integrate agentic verification

Request API access, connect your agent or orchestrator, send a verification request, receive a machine-readable response, and act on the response. Optionally log proof metadata and policy outcome for audit.

Agent requests trust signal. Your agent or workflow engine calls the AffixIO API with the verification context.
Receive binary verification output. The API returns a structured result (e.g. verified true/false, proof token).
Route decision into workflow engine. Use the result to approve, gate, or route the next step in your pipeline.

Examples

Sample response patterns

Verify eligibility

{"verified":true,"proof":"zk_...","context":"eligibility"}

Eligibility check returns a boolean and optional proof. Use for benefits, programme access, or eligibility verification flows.

Verify permission

{"verified":true,"scope":"access","expires_utc":"..."}

Permission check confirms whether the requested action is allowed. No identity data is returned.

Verify payment condition

{"verified":true,"payment_ok":true,"proof":"..."}

Payment-related verification for agentic or offline payment flows. No PAN or card data is passed through AffixIO.

Verify access state

{"verified":true,"access_granted":true}

Access state check for gates, venues, or ticketing. Binary result for machine-led entry or routing.

FAQ

Common questions

What is machine-to-machine verification?

Machine-to-machine (M2M) verification is when an autonomous agent or system requests a verification decision and receives a machine-readable signal (e.g. yes/no, proof token) without human involvement. AffixIO returns cryptographic verification signals that agents can act on directly.

How do autonomous agents use AffixIO?

An agent or workflow engine sends a verification request to the AffixIO API. AffixIO evaluates the request using policy and proof logic and returns a binary or structured result. The agent uses that result to approve, gate, or route the next step. No human is required in the loop.

Does AffixIO expose identity data to the agent?

No. AffixIO returns only the verification outcome (e.g. verified true/false) and optional proof metadata. No PII or raw identity data is transmitted to the agent. The design is privacy-preserving and minimises exposure.

Why is this PCI-DSS zero scope?

AffixIO does not store PAN or act as the money mover. The system operates on verification signals rather than raw card data. The AffixIO layer is therefore outside the cardholder data environment, supporting a PCI-DSS zero scope architecture for our component.

What does stateless ZK backing mean in practice?

Verification is backed by stateless architecture: no session or server-side state between requests. Proof logic can confirm a condition without oversharing underlying data. Outputs are suitable for machine decisioning and support privacy, auditability, and portability.

Can AffixIO be used for payments and access workflows?

Yes. AffixIO is usable across payments (e.g. agentic payment approval, offline payment verification), access (gates, venues), eligibility verification, and ticketing. The same verification layer applies to multiple use cases.

How do developers integrate agentic verification?

Request API access from AffixIO, connect your agent or orchestrator to the API, send verification requests with the required context, and handle the machine-readable response. Optionally log proof metadata for audit. See the technical architecture and contact for integration support.
