Aggregate wallet stats (tx count, volume, unique recipients) from the x402 payment 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 0x39020c1942e554cf494738720a40ee62903b9f4f), it returns metrics such as transaction count, total transfer volume, and unique recipients. The data covers x402 protocol USDC transfers on Base and Solana chains.
The endpoint is part of x402scan, a payment data explorer and analytics dashboard built by Merit Systems. It indexes on-chain x402 micropayment activity across multiple facilitators (Coinbase, PayAI, Meridian) and chains. Optional query parameters allow filtering by chain (base or solana) and timeframe (1, 7, 14, or 30 day lookback). The cost is $0.01 per request, paid via the x402 protocol with an X-Payment header.
Note that the probe returned 404 for this specific wallet address on both GET and POST, which likely means this particular address has no indexed data rather than the endpoint being down. The broader x402scan API and its OpenAPI spec are well-documented, and the parent site returned 200 with live ecosystem stats showing ~97K daily transactions.
Capabilities
Use cases
- —Retrieve aggregate payment statistics for a specific wallet participating in the x402 ecosystem
- —Monitor a wallet's x402 spending activity over configurable time windows
- —Compare wallet activity across Base and Solana chains
- —Build dashboards tracking x402 protocol adoption per wallet
- —Audit an agent's cumulative micropayment spending
Fit
Best for
- —Developers building analytics on x402 protocol usage
- —AI agents needing to inspect their own payment history
- —Researchers studying micropayment ecosystem activity
- —Wallet monitoring and alerting tools
Not for
- —General-purpose blockchain explorers (covers only x402 USDC transfers, not all on-chain activity)
- —Querying wallets with no x402 transaction history (returns 404)
- —Real-time streaming of transactions (this is an aggregate stats endpoint)
Quick start
curl -X GET \
'https://www.x402scan.com/api/x402/wallets/0xYOUR_ADDRESS/stats?chain=base&timeframe=7' \
-H 'X-Payment: <x402_payment_token>'Endpoint
Quality
The OpenAPI spec is thorough with clear parameter definitions and pricing, but the specific endpoint probed returned 404 (likely due to the hardcoded wallet address having no data). No response schema or example responses are documented. No dedicated docs page exists.
Warnings
- —Probe returned 404 for this specific wallet address on both GET and POST — the address may have no indexed x402 data. The endpoint pattern /api/x402/wallets/{address}/stats is documented and likely works for wallets with activity.
- —No response schema is provided in the OpenAPI spec — the shape of the returned JSON is unknown.
- —The listing URL contains a hardcoded wallet address; the general endpoint pattern is /api/x402/wallets/{address}/stats.
