Aggregate wallet stats (tx count, volume, unique recipients) from the x402 protocol ecosystem for $0.01 per call.
What it does
This endpoint returns aggregate statistics for a specific wallet address within the x402 payment ecosystem. Given a wallet address (in this case `0x69a8e5daff3ee5e7d790b4a61cbefa9e86986893`), it reports metrics such as transaction count, total transfer volume, and unique recipients. Results can be filtered by chain (Base or Solana) and by timeframe (1, 7, 14, or 30 days lookback).
x402scan is a payment data explorer and analytics dashboard for the x402 protocol, built by Merit Systems. It indexes USDC micropayment transfers across Base and Solana, tracking buyers, merchants (sellers), facilitators, and registered x402 resources. The platform exposes a suite of data query endpoints — all payable via x402 micropayments — covering wallet transactions, merchant stats, facilitator analytics, resource search, and a registry for discovering x402-protected APIs.
This specific wallet stats endpoint costs $0.01 USD per request, settled via the x402 protocol. It accepts optional `chain` and `timeframe` query parameters. Note that the probe returned HTTP 404 rather than the expected 402 challenge, which may indicate the specific wallet address in the URL is not indexed, or the endpoint path uses a different prefix (`/api/x402/wallets/` vs `/api/data/wallets/`). The OpenAPI spec documents the canonical path as `/api/x402/wallets/{address}/stats`.

Quick start

Quality
Full OpenAPI spec is available with clear parameter definitions and pricing info, but the probed endpoint returned 404 (possibly wrong path prefix /api/data/ vs /api/x402/), no response schema is documented, and no example responses are available. The endpoint's liveness at the exact registered URL is uncertain.
Warnings
- —Probe returned HTTP 404 on both GET and POST — the registered URL uses path prefix /api/data/wallets/ but the OpenAPI spec documents /api/x402/wallets/{address}/stats. The canonical path may differ from the registered one.
- —No response schema is documented in the OpenAPI spec; response shape must be inferred.
- —No example responses are available from docs or crawl.
