ImmutableProof

What it is

ImmutableProof is a verification service for Immutable Notice Protocol (INP) v1.0. It returns deterministic verification results and deterministic JSON errors.

What it proves

• That a specific payload matches the INP v1.0 rules and signatures for the supplied inputs.
• That verification is deterministic and does not depend on network/time/locale/state.

What it does not prove

• Truthfulness, legality, intent, agreement, identity beyond key control, or compliance.
• Anything about content meaning; this is a cryptographic verification service only.

Public API

Only API v1 is exposed on the public host. v1 behavior is frozen; changes happen only via /v2 (which is blocked publicly).

• GET /healthz → {"ok":true}
• GET /v1/health → {"ok":true}
• POST /v1/verify → deterministic verification; rejects non-canonical JSON deterministically
