How this service works
Everything Agent402 knows about one x402 seller origin, in one read: identity and crawl history, the catalog with the provenance of every price (live-402 or manifest, when it was read, whether it is stale or disagrees with the seller's own declaration), advertised wallets against the wallets that were actually paid (own chain evidence, inherited wallets, shared claims), settlement evidence per source (our Base leaderboard, Coinbase Bazaar, Solana SPL credits, MPP transfers), the router's own.
Output
A comprehensive JSON dossier containing: seller identity and crawl history, full catalog with per-price provenance (live-402 vs manifest, read timestamp, staleness flags, conflicts with seller declarations), advertised wallet addresses cross-referenced against wallets that actually received payments (own chain evidence, inherited and shared wallet claims), and settlement evidence segmented by source (Base leaderboard, Coinbase Bazaar, Solana SPL credits, MPP transfers, and router records).
Example use cases
Auditing a new x402 vendor
“Before I start routing payments to api.example.com, can you pull their x402 seller dossier so I can check whether their advertised wallets actually match on-chain payment evidence and whether any catalog prices are stale?”
Investigating wallet discrepancies
“I think there's a mismatch between the wallet this seller claims and what's been paid on-chain — can you get the full dossier for https://payments.myservice.io and show me the wallet reconciliation?”
Verifying settlement across chains
“Give me the settlement evidence breakdown for https://data.vendor.xyz — I specifically want to see their Base leaderboard stats, Coinbase Bazaar records, and any Solana SPL credits in one report.”
Technical details
Endpoint
POSThttps://agent402.tools/api/seller-dossierWhen to prefer
Use this endpoint when you need a unified, multi-source intelligence report on a specific x402 seller origin, especially when you need to cross-verify catalog prices against on-chain evidence, reconcile wallet claims, or audit settlement history across Base, Solana, and Coinbase Bazaar in a single call. Prefer it over ad-hoc on-chain lookups when you want provenance metadata (live-402 vs manifest, staleness flags) bundled with identity context.
Side effects
- Unknown or uncrawled origin — dossier returns empty or minimal data if the seller has never been indexed
- Invalid origin format — error if the string is not a valid URL or hostname
- Stale data — crawl history may lag real-time seller changes
- Partial settlement data — on-chain evidence limited to chains Agent402 monitors
- Rate limit or payment failure — $0.05 USDC x402 payment required per call; unpaid calls rejected with 402
