How this service works
x402 seller attribution intelligence: reported calls versus catalog-attributed on-chain USDC flow, payer-address concentration and forensic signals. Attribution is not protocol or fraud proof.
Output
Returns a structured report for the given payTo address including: ratio of reported API calls to catalog-attributed on-chain USDC flow, payer address concentration metrics, forensic anomaly signals, and an overall attribution quality assessment. Note: attribution is not protocol-enforced or fraud-proof.
Example use cases
Auditing a suspicious x402 seller
“I'm considering buying from an x402 seller with payTo address 0xABCD...1234 — can you check their attribution intel to see if their claimed call volume actually matches the USDC flowing on-chain, and flag any payer concentration issues?”
Marketplace due diligence before listing
“Before we feature this x402 API in our catalog, run the attribution authenticity check on their payTo address 0x9f2e...88a1 and tell me if the on-chain USDC receipts are consistent with what they're reporting.”
Forensic investigation of payment anomalies
“I noticed some weird patterns in payments to 0x7c1d...5fe3 on the x402 network — run the seller attribution intelligence on that address and show me the forensic signals and payer concentration breakdown.”
Technical details
Endpoint
GEThttps://api.x402intel.uk/x402-authenticity/:payTo?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to cross-reference an x402 seller's self-reported API usage against verifiable on-chain USDC flows for a specific payTo address. Prefer this over generic blockchain explorers when you want pre-computed concentration metrics and forensic signals specific to the x402 marketplace ecosystem.
Side effects
- Unknown payTo address returns empty or null attribution data
- Addresses with no on-chain USDC activity return zero-flow reports with limited forensic signals
- Rate limiting or payment failure returns 402 or 429 error
- Malformed wallet address format triggers a 400 validation error
- Newly registered sellers may have insufficient history for meaningful attribution
