SDK for apps and devices
The software kit helps your engineers wire flows, carry policy references, and handle proof bundles in code. It does not phone home and it does not cache user records.
SDK
Stateless verification infrastructure
Stateless verification infrastructure with API and SDK.
AffixIO is verification infrastructure you plug in behind your own products. It is stateless by design, which means it does not keep a hidden user database, and it does not sit on long term records about your customers. You send a request, it returns a clear yes or no with proof, and the request is done. Banks, payment platforms, and public sector buyers use AffixIO because the answers can be audited, the data stays where it should, and the same wiring runs offline, online, or both at once.
Stateless by design Routine checks do not need AffixIO to store long term records about people.
Offline or online Same idea at a quiet store lane and at a busy data centre.
Ready for stronger cryptography The design leaves room to adopt stronger maths when standards settle.
Plug it in
Most teams start with the HTTP service and add the software kit where it saves time in apps and devices. Both pieces talk to the same stateless core.
Stateless core
AffixIO checks the request against your rules and trusted signals, returns yes or no with proof, and then drops the request. Your risk and audit colleagues get material they can read and follow.
Core serviceAPI
Stable URLs and versions so operations teams know what changed and when. Every call stands on its own, which is what stateless means in practice.
APIWorks offline and online
Some sites need to keep going when the network drops. Others live in the cloud. AffixIO handles both cases because the core is stateless. There is no session to lose between calls, and no central queue to rebuild after a quiet patch. Product teams write the verification once and use it in every channel.
When the line drops
Devices can carry signed proofs forward and reconcile later when the connection comes back. Your privacy rules stay intact because nothing about the customer is held by AffixIO between calls.
When everything is up
Central teams push tight policy updates and get fast responses. Downstream systems stay in step because each verification call carries everything it needs to make the answer make sense.
Same building block. Payments, gates, eligibility checks, and automated actors call the same stateless verification.
Many uses, one block
You integrate the stateless core once at the centre. Each line of business still speaks its own language at the edge, and they all share the same verification pattern.
Payments
Cards, wallets, and terminals ask whether a charge should move ahead, and get a stateless yes or no with proof.
Eligibility
Pricing, subsidies, and access rules become one verified answer instead of many scattered lookups.
Access gates
Doors, accounts, and privileged actions follow the policy windows you set, online or offline.
Automated actors
Software agents run inside the budgets and consent you set. More detail lives on our AI hub.
Risk and compliance
Reviewers see evidence they can trace through the system, not a silent yes from a black box.
Security that ages well
Quantum computers will one day threaten some of the encryption we rely on now. AffixIO keeps routine transport separate from the proof material, so you can upgrade algorithms later without rebuilding every integration. The stateless design also means there is no large store of historic checks waiting to be re-encrypted, because the historic checks were never kept in the first place.
Hold less, prove more
Day to day checks aim to store less inside AffixIO, not more. Sensitive details stay where your contracts and regulators already expect them. Proof outputs carry what audits need, without copying whole identity files into a new silo. Buyers who want a stateless setup get one as the default, not as an extra tier.
How it works
Three plain steps from request to answer.
Step 1
You describe the decision
You send who or what is asking, what they want to do, the limits that apply, and which version of your rulebook should be used. The format is the same for a live call and an offline packet.
Step 2
AffixIO checks the facts
Checks run against your policies and trusted sources. Raw sensitive fields stay in systems you already control whenever the design allows it.
Step 3
You get yes or no
The reply is explicit and comes with proof. You can file it, replay it later, or hand it to a partner so that everyone sees the same story. AffixIO then forgets the request, because it is stateless by design.
Where it fits
Think of AffixIO as a thin stateless layer between customer touchpoints and the systems that move money, open doors, and update records. It does not replace anything you already run. It sits in the middle and answers questions.
