How this service works
Deterministic procedure for agents grading a merchant's claimed on-chain x402 payment history before trusting its reputation or volume-derived metrics. Screens for fictitious activity: self-payment loops (payer equals payee or a controlled wallet), single-controller multi-wallet clusters, linked-cluster concentration, and burst timing inconsistent with independent demand. Returns an authenticity grade, per-signal evidence tuple, and a trust decision: rely on the volume, discount it, or refuse
Output
Returns a JSON object containing: an authenticity grade, a per-signal evidence tuple covering self-payment loops, multi-wallet cluster concentration, and burst timing anomalies, a trust decision (rely / discount / refuse), a human-readable decision procedure prose brief for agents, the generation source (llm, reasoning, or deterministic), and an ISO-8601 timestamp.
Example use cases
Pre-deal merchant due diligence
“I'm about to onboard a new merchant claiming a high x402 settlement volume. Can you run a settlement authenticity screen on their payment history and tell me whether their reputation metrics are trustworthy or if there are signs of wash trading or self-payment loops?”
Autonomous agent counterparty gating
“Before my agent agrees to route payments through this merchant node, screen their on-chain x402 history for fictitious activity — I need to know if I should trust their claimed volume or reject them outright.”
Reputation fraud investigation
“A merchant is disputing a low trust score and claiming their x402 payment volume proves legitimacy. Can you do an authenticity screening and return the per-signal evidence so I can see exactly which signals triggered the discount or refusal decision?”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/settlement-authenticity-screening-for-agent-repu?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to vet a merchant's on-chain x402 reputation before trusting volume-derived metrics or granting counterparty status. It is specifically designed for the x402 payment ecosystem and applies deterministic fraud-detection signals (self-payment loops, wallet clustering, burst timing) that general blockchain analytics tools do not target. Prefer this over generic on-chain analytics when you need a structured trust decision (rely/discount/refuse) with per-signal evidence rather than raw transaction data.
Side effects
- Missing or malformed input wallet/topic parameter returns an error response
- Payment not received (x402 unpaid) results in no substantive result returned
- If the merchant's on-chain history is insufficient or unavailable, the screen may return inconclusive results
- Rate limiting or service unavailability at k2so.wrong.systems may cause timeout
- Invalid query parameter values (e.g. unsupported method type) return a schema validation error
