It is part of x402scan, a payment data explorer and analytics platform for the x402 protocol, built by Merit Systems. The endpoint is located at `/api/x402/wallets/{address}/transactions` and accepts query parameters for pagination (page, page_size), chain filtering (base or solana), timeframe lookback (1, 7, 14, or 30 days), and sorting by time or amount in ascending or descending order.\n\nEach call costs $0.01 USD, paid via the x402 micropayment protocol (X-Payment header). The specific URL listed here has the address `0xD12d26DE05d5Ee5965569C513c4B6A0f39d95f8A` hardcoded in the path, but the underlying OpenAPI spec defines this as a parameterized `{address}` path. The endpoint supports Base and Solana chains. Note that the probe returned 404 for this specific address, which may indicate the address has no indexed data or the endpoint requires a valid x402 payment header to resolve properly — the broader x402scan origin is live (HTTP 200 on root).\n\nThe x402scan platform indexes x402 payment activity across the ecosystem, tracking transactions, merchants, buyers, facilitators, and registered resources. The dashboard shows significant activity: roughly 97K transactions and $17K in volume in the past 24 hours at time of crawl, with facilitators including Coinbase, PayAI, and Meridian.","tags":[],"capabilities":["wallet-transaction-history","x402-micropayment","pagination","chain-filtering","time-range-filtering","sort-by-time","sort-by-amount","base-chain","solana-chain"],"categories":["blockchain","analytics","search"],"synonyms":["x402 wallet transactions","x402 transfer history","x402scan wallet lookup","blockchain payment explorer","x402 sender transactions","USDC transfer history","wallet activity API","x402 payment data"],"warnings":["Probe returned 404 for both GET and POST on this specific wallet address — the endpoint may require a valid x402 payment header or the address may have no indexed data.","No response schema defined in the OpenAPI spec — response structure must be inferred.","No example responses available from docs or crawl.","The listed URL hardcodes a specific wallet address; the general parameterized endpoint is /api/x402/wallets/{address}/transactions."],"endpointUrl":"https://www.x402scan.com/api/data/wallets/0xD12d26DE05d5Ee5965569C513c4B6A0f39d95f8A/transactions","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x2EC4545f96A24876764bF2B04D54E66A1351bE71","amount":"10000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300}]},"qualityScore":"0.550","qualityRationale":"The OpenAPI spec is well-documented with clear parameter definitions and pricing info, but the specific probed URL returned 404 (not a 402 challenge), no response schema is defined, and no example responses are available.
