Paginated list of all indexed x402 resources across Base and Solana chains for $0.01 per call.
What it does
x402scan is a payment data explorer and registry for the x402 protocol, built by Merit Systems. This specific endpoint (`GET /api/x402/resources`) returns a paginated list of all indexed x402-protected resources. It supports filtering by chain (Base or Solana) and pagination via `page` (0-based) and `page_size` (1–100, default 10) query parameters. Each call costs a fixed $0.01 USD micropayment via the x402 protocol.
The endpoint is part of a broader x402scan API suite that includes wallet/merchant/facilitator analytics, full-text resource search, registry management, and a USDC send endpoint. Data endpoints are priced at $0.01–$0.02 per request, while registry write endpoints use SIWX wallet authentication and are free. The API is documented via an OpenAPI 3.1.0 spec served from the origin.
Note: During probing, the endpoint at the cataloged URL (`/api/data/resources`) returned 404, while the OpenAPI spec defines the resource listing at `/api/x402/resources`. The correct canonical path appears to be `/api/x402/resources`. The x402scan dashboard shows active ecosystem stats (97K+ transactions, $17K+ volume in 24 hours at time of crawl), indicating the platform is actively used.
Capabilities
Use cases
- —Discovering all available x402-protected API endpoints across Base and Solana
- —Building dashboards or aggregators that track the x402 ecosystem
- —Finding x402 resources filtered by blockchain network
- —Programmatic enumeration of x402 services for agent routing
Fit
Best for
- —AI agents that need to discover x402-payable endpoints
- —Developers building on the x402 protocol who need a resource directory
- —Analytics platforms tracking x402 ecosystem growth
- —Wallet applications that want to display available x402 services
Not for
- —Use cases requiring free/unauthenticated access (every call costs $0.01)
- —Querying non-x402 blockchain data or general-purpose block exploration
- —Real-time streaming of resource updates
Quick start
# Fetch first page of x402 resources (requires x402 payment header)
curl -X GET 'https://www.x402scan.com/api/x402/resources?page=0&page_size=10' \
-H 'X-Payment: <x402_payment_token>'Example
Request
{
"url": "https://www.x402scan.com/api/x402/resources?page=0&page_size=10&chain=base",
"method": "GET",
"headers": {
"X-Payment": "<x402_payment_token>"
}
}Endpoint
Quality
Full OpenAPI 3.1.0 schema with clear parameter definitions and pricing metadata. However, the probed URL (/api/data/resources) returned 404 while the spec defines /api/x402/resources, suggesting the cataloged URL is incorrect. No response schema or example responses are provided. The platform appears active based on dashboard stats.
Warnings
- —The cataloged endpoint URL (/api/data/resources) returned 404 on both GET and POST. The correct path per the OpenAPI spec is /api/x402/resources.
- —No response schema is defined in the OpenAPI spec — only '200: Successful response' without a body schema.
- —No example response data is available; the response structure must be inferred at runtime.
