Query paginated x402 payment transactions sent by a specific wallet address.
What it does
This endpoint is part of x402scan, a payment data explorer and analytics platform for the x402 protocol, built by Merit Systems. It returns paginated USDC transfer records where the specified wallet address is the sender, covering both Base and Solana chains. Results can be filtered by chain and timeframe (1, 7, 14, or 30 days lookback), and sorted by time or amount in ascending or descending order.
The endpoint is located at `/api/x402/wallets/{address}/transactions` and costs $0.01 per call, paid via the x402 micropayment protocol. The specific URL listed here uses a hardcoded wallet address (`0x4D37f28D2db99e8d35A6C725a5f1749A085850a3`), but the same path pattern works for any wallet address. Pagination is 0-based with a configurable page size of 1–100 items (default 10).
Note: The probe returned 404 for this specific endpoint URL, which may indicate the particular wallet address has no indexed data, or there is a path-routing issue between the `/api/data/` prefix in the listed URL and the `/api/x402/` prefix documented in the OpenAPI spec. The OpenAPI spec documents the canonical path as `/api/x402/wallets/{address}/transactions`. The broader x402scan platform is live (root returns 200) and the OpenAPI spec is well-documented with 13 endpoints covering wallet transactions, merchant data, facilitator stats, resource registry, and USDC sending.

Quality
The OpenAPI spec is thorough with clear parameter definitions and pricing, but the specific probed URL returned 404 (possibly due to a /api/data/ vs /api/x402/ path mismatch). No response schema or example responses are documented. No dedicated docs page exists.
Warnings
- —Probe returned 404 on both GET and POST — the listed URL uses '/api/data/wallets/...' but the OpenAPI spec documents the path as '/api/x402/wallets/{address}/transactions'. The canonical path may differ from the registered endpoint URL.
- —No response schema is provided in the OpenAPI spec — response body structure must be inferred at runtime.
- —No dedicated documentation page found (x402scan.com/docs returns 404).
