Purpose and usage

What this endpoint does

List attestations issued to or visible by the caller.

When to use it

List formal issuer statements visible to the subject when a relying workflow needs commitment-level eligibility evidence without private claim values.

OUTCOME · Verify

What changes

Read-only projection; it grants no mutation, settlement, traffic, or authority change.

WHY IT MATTERS

Gives people and agents a contract-backed way to verify attestations.
Separates subject identity, consent, evidence, provider output, review, issuer credentials, and relying-party acceptance instead of collapsing them into a universal trust score.

ISOLATION + AUTHORITY

Bearer subject, tenant, purpose, policy version, role, issuer, reviewer, provider, and relying-party boundaries remain distinct. The response or transition grants no payment, custody, settlement, publisher, matching, or trading authority and must not expose regulated evidence beyond the live schema.

BEFORE YOU CALL

Authenticate at the documented boundary: bearer+scope.
Use the live OpenAPI schema as the authority for the exact request shape and response model.
Resolve the applicable purpose, policy version, consent or role basis, and required assurance before relying on this result.

WHAT TO DO NEXT

Compare the returned commitment, signer, policy, lifecycle, and freshness fields with the caller's acceptance rules.
Use the returned lifecycle state and policy version to choose the next least-privilege trust action; do not infer a missing stage.

AGENT GUIDANCE

Use attestations only for the purpose and lifecycle stage described by this operation; do not treat it as authority for an adjacent action.
Use the live OpenAPI schema as the authority for the exact request shape and response model.
Treat policy availability, consent, evidence capture, completed checks, review, decision, credential issuance, validity, and relying-party acceptance as separate facts.
Use response links and canonical identifiers instead of constructing internal service URLs or scraping the website.

INTEGRATION DECISION

CALLER ACTION: Accept the returned representation or receipt, then compare the returned commitment, signer, policy, lifecycle, and freshness fields with the caller's acceptance rules.
RETRY SAFETY: Repeat only when the integration needs a fresher authoritative projection.
STATE RECONCILIATION: Use returned identifiers and versions as the comparison point for later reads. Refresh the subject, claim or credential version, issuer and reviewer authority, evidence commitment, decision, expiry, and revocation status.

401The bearer credential is missing or invalid.Authentication required · JSON RESPONSE+

{
  "code": "invalid_credentials",
  "message": "The bearer credential is missing or invalid."
}

INTEGRATION DECISIONinvalid_credentials

CALLER ACTION: Discard the rejected credential, complete the documented authentication or reassertion flow, and rebuild any request signature with fresh timestamps and nonces.
RETRY SAFETY: Retry only with a newly valid credential and fresh replay-protection values. Do not replay an expired signature.
STATE RECONCILIATION: Authentication failed before an authoritative read was returned for subject-scoped trust claims, evidence, credentials, reviews, decisions, presentations, and revocations.
ESCALATE WHEN: Escalate when subject binding, evidence minimization, issuer or reviewer authority, decision lineage, expiry, or revocation cannot be established.

403The credential lacks exact trust:read authority.Authority or policy denied · JSON RESPONSE+

{
  "code": "insufficient_scope",
  "message": "The credential lacks exact trust:read authority."
}

INTEGRATION DECISIONinsufficient_scope

CALLER ACTION: Verify the exact scope, tenant or workspace membership, owner boundary, step-up purpose, feature policy, and resource eligibility. Never broaden authority automatically.
RETRY SAFETY: Do not retry until the missing authority or policy condition has been deliberately resolved with least privilege.
STATE RECONCILIATION: Confirm the caller and resource resolve to the same authority boundary for subject-scoped trust claims, evidence, credentials, reviews, decisions, presentations, and revocations.
ESCALATE WHEN: Escalate when subject binding, evidence minimization, issuer or reviewer authority, decision lineage, expiry, or revocation cannot be established.

503The authoritative Identity trust service is unavailable.Dependency unavailable or outcome uncertain · JSON RESPONSE+

  "code": "identity_unavailable",

}

INTEGRATION DECISIONidentity_unavailable

CALLER ACTION: Treat the failure as transient and preserve the last known good representation without presenting it as fresh.
RETRY SAFETY: Retry with bounded exponential backoff and jitter; stop after the integration's failure budget is exhausted.
STATE RECONCILIATION: Refresh the subject, claim or credential version, issuer and reviewer authority, evidence commitment, decision, expiry, and revocation status.
ESCALATE WHEN: Escalate when subject binding, evidence minimization, issuer or reviewer authority, decision lineage, expiry, or revocation cannot be established.

OPERATIONAL NOTES

Security and lifecycle guarantees

Evaluate status, valid_from, valid_until, issuer_signature_valid, proof_type, encoding, and each commitment together under the relying policy. No single field is sufficient.
Commitments are not cleartext, consent, or universal authority. value_type, assurance_level, and verification_status may be null on older or purpose-limited statements.
This collection accepts no query parameters or body and is returned no-store. Issuance, presentation, challenge, verification, status updates, and reviewer actions remain separate planned contracts.

Reference version and availability details

This route is implemented in canonical gateway source and appears in the production OpenAPI snapshot observed 2026-10-02T23:27:55.510Z. Authentication, tenant, feature, venue, and market policy still apply.
