Build against the same canonical proof transaction.
Documentation for deterministic verification, registry resolution, signed events, webhooks, SDKs, MCP contracts, lifecycle control, and Test Mode boundaries.
Quickstart
Run a deterministic verification, inspect the credential, resolve the public record, and verify the signed-event trail.
API reference
Schema-validated Test Mode endpoints backed by separate evidence-eligibility and issuer-authority decisions with canonical projections.
SDKs
Typed integration patterns for TypeScript and Python using the same public contract.
MCP tools
Machine-callable operations expose scoped proof without allowing an AI system to invent evidence or authority.
Webhooks
Signed event delivery with inspectable attempts, deterministic retry schedules, and manual replay.
Signed events
Append-only deterministic events connect verification, evidence binding, claim resolution, issuance, registry publication, webhook delivery, and lifecycle control.
Test Mode
Deterministic fixtures exercise the production contract without representing live customers, production metrics, or authoritative credentials.
Trust remains inspectable.
Every Test Mode result carries its evidence scope, policy result, signature state, lifecycle state, registry projection, and machine-readable response.
