Query x402 protocol facilitator data — list facilitators with stats, filtered by chain and timeframe.
What it does
The x402scan Facilitators endpoint returns a paginated list of facilitators (payment processors) active in the x402 ecosystem, along with their aggregate statistics such as request counts, volume, buyer counts, and seller counts. It is one of several data endpoints offered by x402scan, a payment data explorer and registry for the x402 protocol built by Merit Systems.
This specific endpoint (GET /api/x402/facilitators) costs $0.01 per call, paid via an x402 micropayment in the X-Payment header. Results can be filtered by chain (Base or Solana) and by timeframe (1, 7, 14, or 30 days lookback), and are paginated with configurable page size (1–100 items). The broader x402scan API suite includes endpoints for wallets, merchants, resources, full-text search, a resource registry, and a USDC send function — all priced between $0.01 and $0.02 per query.
The x402scan dashboard shows live ecosystem stats: at the time of crawl, the platform tracked roughly 97K transactions and $17K in volume over the past 24 hours across facilitators including Coinbase, PayAI, and Meridian. The API is documented via an OpenAPI 3.1.0 spec served from the origin. Note that the probe returned 404 on this specific path (possibly due to a routing prefix mismatch between /api/data/facilitators and the documented /api/x402/facilitators), so callers should use the canonical path /api/x402/facilitators as specified in the OpenAPI document.
Capabilities
Use cases
- —Retrieve a ranked list of x402 facilitators and their transaction volumes for ecosystem monitoring
- —Filter facilitator activity by chain (Base or Solana) and time window for comparative analysis
- —Build dashboards or reports tracking which facilitators process the most x402 payments
- —Programmatically monitor facilitator health and adoption trends in the x402 ecosystem
Fit
Best for
- —Developers building analytics on top of the x402 payment protocol
- —AI agents that need to discover or evaluate x402 facilitators before routing payments
- —Researchers studying micropayment ecosystem adoption on Base and Solana
Not for
- —General-purpose blockchain explorers — this is specific to x402 protocol transfers only
- —Users needing free or API-key-authenticated access — every call requires an x402 micropayment
Quick start
curl -X GET 'https://www.x402scan.com/api/x402/facilitators?page=0&page_size=10&chain=base&timeframe=7' \
-H 'X-Payment: <x402_payment_token>'Endpoint
Quality
Full OpenAPI 3.1.0 schema with clear parameter definitions and pricing metadata. However, the probe returned 404 on the listed endpoint path (/api/data/facilitators vs /api/x402/facilitators), no response body examples are provided in the spec, and no dedicated documentation pages exist. The endpoint is likely live at the canonical /api/x402/ path but could not be confirmed via probe.
Warnings
- —Probe returned 404 on /api/data/facilitators — the canonical path per the OpenAPI spec is /api/x402/facilitators; the Bazaar listing URL may be incorrect.
- —No response schema or example responses are documented in the OpenAPI spec.
- —No dedicated docs, pricing, or README pages found on the origin (all returned 404).
