Build a trusted agent transaction.

OATI Hub brings the specification, schemas, SDKs, examples and conformance tools into one developer path. Start with a working object, understand the protocol, then prove that your implementation behaves consistently.

The question it answers

“How do I implement and verify OATI?”

Start with running code

Validate a Passport, evaluate authority and verify a Receipt using maintained examples.

Use open building blocks

Adopt the schemas, CLI, TypeScript SDK, middleware and lookup contract without buying a commercial product.

Test interoperability

Run shared fixtures, cryptographic vectors and conformance suites before making compatibility claims.

How it works

A precise part of the trust chain.

Each OATI component has one clear job. Together they create a transaction that another organisation can understand and verify.

01
Add the SDK
Use the reference types, builders, validation and verification tools in your service.
02
Publish a Passport
Give the agent a resolvable identity with current keys and status information.
03
Require a Mandate
Evaluate every protected action against explicit, non-amplifying authority.
04
Return a Receipt
Sign the result so another party can independently verify the transaction evidence.

From first object to conformance report.

The public repository contains everything required to implement and verify the standard independently.

Specification

Normative objects, cryptographic profile and deterministic authority rules.

Schemas

Versioned JSON Schemas for core records and domain profiles.

SDK

TypeScript builders, validation, signing, verification and middleware.

CLI

Validate, canonicalise, sign, resolve and evaluate OATI objects.

Examples

Runnable core, Commerce and real-world asset transaction objects.

Conformance

Shared fixtures, negative cases, test vectors and compatibility reports.
