VERIFICATION-AS-A-SERVICE

Prove a digital file is what you said it is.

Upload any file or URL with a structured spec. Eleven specialised AI agents run the checks in parallel. We sign the result with our key — and anyone, anywhere, can validate the certificate offline.

specialised agents

OCR, colour palette, document text, video frames, audio transcript, code quality, website structure, reference match — each is the world expert in its job.

model consensus

Vision questions go through Claude, GPT, and Gemini in parallel. Only unanimous agreement counts as confident — disagreement routes to manual review.

signed certificates

Every result is a JWT signed by our rotating private key. Verify it offline with our public JWKS — no API call to us required.

How it works in 60 seconds

1

Sign up

Email verification + your API key in two HTTP calls. Free tier is live before you can finish reading this paragraph.

2

POST a verification

Upload the file (or pass a URL) and a structured test plan. Each case names an agent and the precise params it should check.

3

Get a signed certificate

Within seconds, you receive the per-case results plus a JWT. Anyone can verify it against our public JWKS at /.well-known/jwks.json.

Built for the people who can't afford to be wrong

Journalists & fact-checkers

Verify that a leaked document matches the claimed metadata. Confirm a photo wasn't tampered with. Issue a public certificate readers can audit.

Insurance & claims

Validate damage photos against policy specs. Detect duplicates, manipulated EXIF, banned content — automatically, with a signed evidence trail.

Procurement & vendor audit

Confirm vendor deliverables meet the contract before approving payment. Multi-vendor RFP responses scored on the same precise criteria.

Academic & research

Confirm a dataset is what it claims. Verify methodology compliance for journal submissions. Issue cryptographic proofs of submission integrity.

Compliance teams

Enforce brand-asset compliance across hundreds of suppliers without humans-in-the-loop. Every approval has an audit-grade certificate.

Marketplaces

Drop in our API at moderation time. Lift fraudulent listings before they ever reach a buyer. Reduce dispute volume by 60-80%.
