Invinoveritas

Independent verdict on a proposed action before it is taken: a code diff, shell command, deployment plan, configuration change, another agent's output, or a proposed transaction. Returns approve / approve_with_concerns / reject with a confidence score, issues ranked by severity, suggested fixes and alternatives. With sign=true the verdict is returned as a signed proof that anyone can check later with verify_proof. The verdict is a reasoned second opinion, not a guarantee of outcome.

Checks a signed invinoveritas proof without trusting whoever handed it over: recomputes the event id, checks the Schnorr signature, and confirms the signing key is invinoveritas's published key. Optionally pass expect_artifact_hash (sha256 of the content you received) to confirm the proof covers that exact content. Accepts the full event, or an event_id to look up. Returns {valid, checks, proof_payload}. Free, no sign-in. Docs: https://api.babyblueviper.com/verify

Signed receipt for one verdict-governed payment: endpoint, network, asset, max amount, payer, facilitator verdict, settlement id, denial reason, and retry state. retry_state is read from the token's authorizationState, so retrying with the same nonce cannot double-pay. Pass the signed review event and the payment args it bound; optional tx_hash. Refuses unsigned when the verdict does not verify or does not bind those args. The receipt itself checks with verify_proof. Free, no sign-in. Does not move funds.

Check whether a video, audio or image file is byte-for-byte a file a publisher registered with invinoveritas. Pass the file's SHA-256 (compute it locally; the file is not sent). A match returns the registration: per-claim evidential states from its C2PA Content Credentials (signature/hash binding, signer trust, declared edit history, declared AI-generation labels: VERIFIED / DECLARED_ONLY / CONTRADICTED / INSUFFICIENT), any capture tier with its caveat, the signed verdict and the Bitcoin timestamp. No match means not registered, which says nothing either way about the file. A re-encoded copy has a different hash. It never asserts that content is true. Full checks of the file itself: POST /verify-media (upload, free). Free, no auth.

Timestamps and signs a third party's exact claim, unmodified and unjudged: 'we received this text, attributed to source X, at time T', not 'we agree with it'. The source is recorded as self-declared. The resulting proof checks with verify_proof. Docs: https://api.babyblueviper.com/docs

Statistical reality-check of a backtest from its realized returns (or trade rows), not the strategy itself. Returns likely_real / borderline / overfit_or_noise using the Deflated Sharpe Ratio (adjusted for the number of variants tried), a sign-flip permutation test, and out-of-sample decay across purged folds. Inputs are not retained beyond a redacted audit hash. Docs: https://api.babyblueviper.com/docs

Reads invinoveritas's public track record of signed verdicts, including ones that turned out wrong. Each entry is a signed Nostr event whose id and signature can be recomputed against invinoveritas's published key; entries are append-only and Bitcoin-timestamped, so they can't be edited after the fact. No arguments returns the index; pass entry to read one. Free, no sign-in. Docs: https://api.babyblueviper.com/ledger

Publishes one of your own signed review proofs (from review with sign=true) as a public entry on the invinoveritas ledger. Publication is immediate and permanent: the entry is broadcast to Nostr relays and Bitcoin-timestamped. Only genuine invinoveritas-signed proofs are accepted. Docs: https://api.babyblueviper.com/ledger

Publishes a verifier's current conformance grade from the public registry (conformance.json) as a permanent, signed ledger entry, labeled 'certified as of this measurement'. It records the registry's existing measurement and cannot change it. Only works for a verifier currently listed as certified. Docs: https://api.babyblueviper.com/conformance

Audits a public agent or API URL for verifiability: discovery files (llms.txt, MCP card, robots, sitemap), handshake endpoints, and whether presented signed proofs validate. Returns a 0-100 score, a grade, ranked fixes, and a signed proof of the audit. Every result re-derives from a public fetch. Docs: https://api.babyblueviper.com/docs
