It indexes x402 micropayment activity across Base and Solana chains.\n\nThe merchant transactions endpoint accepts query parameters for pagination (page, page_size up to 100), chain filtering (base or solana), timeframe lookback (1, 7, 14, or 30 days), and sorting by time or amount in ascending or descending order. Each call costs $0.01 USD, paid via the x402 protocol (X-Payment header). The endpoint is part of a broader suite of data endpoints on x402scan covering wallets, merchants, facilitators, resources, and a full-text search index.\n\nNote: The specific URL in this listing uses the path `/api/data/merchants/{address}/transactions`, but the OpenAPI spec documents the canonical path as `/api/x402/merchants/{address}/transactions`. The probe returned 404 on the `/api/data/` variant, suggesting the endpoint may have been moved or renamed to the `/api/x402/` path. The `/api/x402/` variant is documented in the OpenAPI spec with full parameter definitions and x402 payment info.","tags":[],"capabilities":["merchant-transaction-history","paginated-results","chain-filtering","timeframe-filtering","sort-by-time","sort-by-amount","x402-micropayment-auth"],"categories":["blockchain-data","payments","analytics"],"synonyms":["x402 merchant transactions","x402 payment history","USDC transfer log","merchant payment explorer","x402scan merchant data","on-chain payment records","x402 block explorer"],"warnings":["The probed URL path /api/data/merchants/{address}/transactions returned 404; the OpenAPI spec documents the endpoint at /api/x402/merchants/{address}/transactions instead — the listing URL may be stale or renamed.","No response schema is provided in the OpenAPI spec — response structure must be inferred.","No dedicated documentation page was found (x402scan.com/docs returns 404)."],"endpointUrl":"https://www.x402scan.com/api/data/merchants/0x4D37f28D2db99e8d35A6C725a5f1749A085850a3/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":"0.500","qualityRationale":"The OpenAPI spec is thorough with parameter definitions and pricing, but the specific /api/data/ URL path returned 404 on probe (likely moved to /api/x402/ path).
