verify_token
Verify that a JSON Web Token was minted by this Obelisk Gate (ES256, correct issuer) and report its type, subject, assurance, and principal. Never returns secrets.

Read the public Obelisk Rating (0-100 score, trust band, and trend) for a registered organization by its slug.
verify_agent_run_proof
Verify the structural integrity, agent binding, delegation continuity, and commitments of an Obelisk action-scoped run proof. Does not reveal or infer raw task data.
get_agent_proof
Read an Obelisk agent's public proof vector by opaque proof id. Returns independent claims with freshness and scope; never a scalar trust score or a claim of non-humanness.
transparency_head
Read the current signed transparency head of Obelisk's tamper-evident receipt ledger — pin it and compare later to prove history only extends. Same data as /.well-known/obelisk-transparency.json.
gate_status
Read the Gate's public liveness facts: issuer, served code revision, OIDC availability, and supported protocols. No posture internals.
explain_rating
Deterministically explain what an Obelisk Rating number means: its trust band, how the public scan scores, and what typically moves a score. Pure function of the number — no data is read.
