It returns paginated USDC transfer records where the specified wallet address is the sender. The data covers transactions on both Base and Solana chains.\n\nThe 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 micropayment protocol (X-Payment header). The specific URL listed here has the address 0xF8eF78f84853dDBc30ba6cD75177A935Bc07131d hardcoded in the path.\n\nNote: The probe returned 404 for this specific wallet address path, which may indicate the address has no indexed data or the endpoint routes differently than expected. However, the OpenAPI spec confirms the parameterized route /api/x402/wallets/{address}/transactions is a documented, live endpoint on x402scan. The broader x402scan origin returned HTTP 200 and the OpenAPI schema is fully published.","tags":[],"capabilities":["wallet-transaction-history","paginated-results","chain-filtering","timeframe-filtering","sort-by-time","sort-by-amount","x402-micropayment","base-chain","solana-chain"],"categories":["blockchain","analytics","search"],"synonyms":["x402 wallet transactions","USDC transfer history","x402scan wallet lookup","blockchain payment explorer","x402 sender transactions","wallet transfer log","x402 payment data"],"warnings":["Probe returned 404 for this specific wallet address — the address may have no indexed x402 data, or the endpoint may only respond to known wallets.","No response schema defined in the OpenAPI spec — the shape of returned transaction objects is unknown.","No example responses available from crawl or docs (docs page returns 404)."],"endpointUrl":"https://www.x402scan.com/api/data/wallets/0xF8eF78f84853dDBc30ba6cD75177A935Bc07131d/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 parameters, pricing ($0.01/call), and operation descriptions.
