Vibes-Coded Attest-Verify Endpoint
x402
Vibes-Coded Attest-Verify Endpoint is a paid API for AI agents from vibes-coded.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-11).
Verifies cryptographic attestations by checking Ed25519 signatures, HMAC validity, and claim digest integrity against a canonical preimage for agent-produced work records.

How this service works
Pay-per-call JSON for AI agents: skill search, listing optimization, install plans, productization, and artifact risk scoring. HTTP 402 → USDC. Full skill marketplace on-site.
Output
Returns a JSON object indicating overall validity (ok, valid booleans), plus granular flags for Ed25519 signature validity, HMAC validity, and whether the claim digest matches the recomputed canonical preimage. Also returns the recomputed canonical string and a human-readable verification note.
Example use cases
Pre-payment agent work verification
“Before I release payment to the agent that delivered my market-analysis.pdf, verify its attestation — agent ID is agent-99, the claim digest is a1b2c3d4, delivery timestamp was 2026-09-01T14:00:00Z, and I need both Ed25519 and HMAC signatures confirmed valid.”
Audit trail integrity check
“I'm auditing last month's agent job completions — can you verify the attestation for agent-17's delivery of the compliance-report artifact from 2026-07-15T09:30:00Z and confirm whether the canonical preimage and claim digest still match?”
Multi-agent workflow trust gate
“Our orchestration pipeline needs to gate the next step on verified agent output — please validate the attestation from agent-5's task completion record with claim digest f9e8d7c6 and timestamp 2026-08-20T11:00:00Z before we proceed.”
Technical details
Endpoint
POSThttps://vibes-coded.com/api/v1/outcomes/attest-verify?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent or orchestration layer needs to cryptographically verify that another agent's work attestation is authentic and untampered — specifically when you require both Ed25519 and HMAC dual-signature validation plus canonical preimage reconstruction in a single pay-per-call call. Prefer this over manual signature checking when operating in an agentic pipeline with USDC micropayment infrastructure already in place.
Side effects
- Invalid or tampered Ed25519 signature returns valid:false with ed25519_valid:false
- HMAC mismatch returns hmac_valid:false indicating payload tampering
- Claim digest mismatch returns claim_digest_matches:false if preimage reconstruction fails
- Malformed or missing required fields (agent ID, digest, timestamp) returns a 400 error
- Payment not included or insufficient triggers HTTP 402 requiring USDC payment before retry
- Unknown resource identifier returns an error indicating unrecognized attestation context
