How this service works
Synthex Forge x402 Receive: 41 paid verification, attestation and governance endpoints (Ed25519 + SHA-256 signed artifacts) plus free verify/public-key/standard sibling routes. Paid routes answer HTTP 402 with an x402 v2 `payment-required` envelope (atomic USDC on Base mainnet, chain ID 8453). Free routes are declared with `security: []` per the x402scan discovery spec.
Output
Returns a JSON object with an 'ok' boolean indicating success, along with a cryptographically signed reputation score artifact (Ed25519 + SHA-256) for the submitted subject endpoint or DID, computed from the provided events array.
Example use cases
Agent marketplace trust vetting
“Before my agent calls that new payment endpoint at https://payments.vendor.io/v1/charge, can you score its reputation using the last 10 observed interaction events I have logged? I need a signed attestation I can show to the marketplace.”
DID issuer credibility check
“I have a decentralized identifier did:web:issuer.credentials.org and a list of 5 recent issuance events — can you compute a reputation score for that issuer and give me a governance-grade attestation artifact?”
Automated service health governance
“Run a reputation assessment on https://data.myplatform.io/v1/query using these 20 observed behavioral events from the past week, including 3 errors and 17 successes, and return a signed reputation score I can store in our compliance log.”
Technical details
Endpoint
POSThttps://x402.synthexforge.com/v1/bureau/reputation?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cryptographically attested, governance-grade reputation score for a specific API endpoint URL or DID issuer, especially within Web3 or agent-to-agent trust frameworks where signed artifacts and on-chain payment settlement (USDC on Base) are required. Prefer this over informal heuristics or manual review when audit trails and tamper-evident attestations matter.
Side effects
- Missing or invalid 'subject' field returns a 400-level error
- Empty or malformed 'events' array may result in an indeterminate or low-confidence score
- Payment not fulfilled results in HTTP 402 with x402 v2 payment-required envelope requiring USDC on Base mainnet (chain ID 8453)
- Invalid event object schema within the array may cause rejection or partial scoring
- Subject URL or DID not resolvable may reduce scoring fidelity
