NOMOS Trust Passport

A verifiable trust record for AI agents.

A NOMOS Trust Passport gives an AI agent a public, cryptographically verifiable record of identity, assessment scope, lifecycle, integrity and revocation status — checkable by a human or a machine.

Why it exists

AI agents can call APIs, initiate payments, access tools, trigger workflows and act across platforms. An ordinary website, profile or self-description does not prove an agent's current, independent status.

Agents, platforms and integrators increasingly need a machine-readable, independently checkable record — not a self-asserted claim. A Trust Passport provides one public, verifiable surface for that.

What the passport contains

Public agent identityA public subject reference and fingerprint.

Credential stateVALID, EXPIRED, REVOKED, INVALID or UNKNOWN.

Assessment levele.g. UNVERIFIED — the depth of verification performed.

Grade & scoreTechnical risk grade and score within a defined scope.

Lifecycle statee.g. BETA.

Integrity verificationCryptographic signature and binding checks.

Revocation statusWhether a revocation is recorded in the current registry.

Registry freshnessHow current the revocation registry is.

Generation bindingThe signed generation the result is bound to.

ExpirationWhen the record expires.

How verification works

A passport record is issued for an agent.
The record is cryptographically signed.
NOMOS verifies integrity, generation and revocation state.
Humans and machines verify the public result via web, JSON, badge or QR.

What the status means

Credential state	VALID, EXPIRED, REVOKED, INVALID or UNKNOWN — the state of the signed credential.
Assessment level	e.g. UNVERIFIED. The level reflects how much independent verification was performed within the scope; it is shown as-is.
Grade / score	A technical risk grade and score within a defined assessment scope — not an overall safety rating.
Lifecycle	e.g. BETA. Interpret displayed lifecycle states as shown.
Revocation	NO_REVOCATION_RECORDED — no revocation was recorded in the current registry at the verification time. This is not a general safety or trust guarantee.

FAQ

What is a NOMOS Trust Passport?: A public, cryptographically verifiable identity and assessment record for an AI agent.
Is it a certification?: No. It is a verifiable record, not a certification, approval or safety guarantee.
What does UNVERIFIED mean?: The assessment level reflects how much independent verification was performed within the scope. UNVERIFIED is shown as-is and is not hidden.
What does Grade C mean?: A technical risk grade within a defined assessment scope — not an overall safety or trust rating.
What does NO_REVOCATION_RECORDED mean?: No revocation was recorded in the current registry at the verification time. It is not a general trust guarantee.
Can software verify it automatically?: Yes — via the JSON API at /api/passports/PASSPORT_ID/verify (schema nomos.trust_passport.verify.v1).
Can I embed the status on my website or GitHub?: Yes — with the SVG badge and a link to the verify page (see the snippets above).
What happens if a passport expires or is revoked?: The verified result and badge reflect EXPIRED or REVOKED; the public result is always live, not cached as positive.
