Cryptographic Proof
for AI Agents
Add tamper-proof receipts and Merkle-anchored attestations to any system output — in one API call. Verify anywhere, by anyone, forever.
One Endpoint. Full Proof.
Send any input/output pair. Get a cryptographic receipt with a Merkle-anchored attestation. No infrastructure changes required.

Works with any system
Proof generated instantly
What’s already built
These controls are implemented and documented in the current repository. No roadmap items. No coming-soon claims.
Cryptographic receipts
Every attestation produces a SHA-256 receipt with Merkle inclusion proof, anchored in a hash-chained transparency log.
Tenant-scoped audit trail
Durable, hash-chained, per-tenant audit log with tamper detection and NDJSON export via authenticated API.
OIDC SSO + SCIM provisioning
OIDC JWT/JWKS authentication, SCIM v2 user lifecycle, role-based access control with 4 roles across all protected routes.
Compliance documentation
SOC 2 Type I evidence package generator, ISO 27001 alignment mapping, and buyer compliance brief — all repo-backed.
Fail-closed design
Missing secrets, invalid auth, replay attempts, and integrity failures all fail closed. No silent fallback. No insecure defaults.
Documented limitations
No SLA in force. No multi-region deployment. No external audit. No penetration test. All gaps are explicitly documented.
