How this service works
Attested x402 payment history for any buyer wallet: settlement count, first-seen, last-seen, total spent, services used,
Output
Returns an attested, Hedera-anchored JSON record containing: total settlement count, first-seen and last-seen timestamps, cumulative USDC spent, list of services the wallet has paid for, and the number of distinct sellers observed — all derived from an append-only ledger and cryptographically anchored on Hedera HCS, making the record tamper-evident and non-revisable.
Example use cases
Pre-deal counterparty wallet vetting
“Before I accept this x402 payment from wallet 0xabc123, can you pull their Rubric payment record so I can see how long they've been active, how much they've spent total, and how many different sellers they've used?”
Fraud screening for new buyer
“A new buyer wallet 0xdef456 just placed an order — can you check their x402 settlement history on Rubric Protocol and tell me if they have a meaningful track record or if this looks like a fresh wallet with no history?”
Audit trail review for compliance
“I need an immutable, Hedera-anchored record of wallet 0x789ghi's x402 payment activity — total settlements, services used, and date range — for our compliance documentation.”
Technical details
Endpoint
GEThttps://rubric-protocol.com/v1/x402/wallet-record/:addressWhen to prefer
Choose this endpoint when you need tamper-evident, blockchain-anchored payment history for a specific buyer wallet — especially when you need evidence-grade counterparty intelligence rather than a behavioral score or reputation opinion. Ideal for pre-transaction due diligence on x402 participants, compliance audits, or fraud screening where immutability and auditability matter. Prefer this over general wallet analytics tools when you specifically need x402 settlement data anchored on Hedera HCS.
Side effects
- Wallet address not found in ledger — returns empty record or 404 if wallet has no x402 settlement history
- Invalid wallet address format — returns 400 with address validation error
- Hedera HCS node temporarily unavailable — may return 503 or delayed response
- No settlement activity for the address — returns record with zeroed counters and null timestamps
- Rate limiting or payment failure — returns 402 or 429 if x402 micropayment is not processed correctly
