How this service works
Fetches an owned, continuously-maintained niche data feed. Current feed `x402-directory`: a probed directory of known x402 services with their live reliability scores, networks, and last-probe timestamps.
Output
A structured directory of known x402 services that have been probed and confirmed to accept x402 micropayments, including their endpoint details and metadata.
Example use cases
Build a payable API marketplace catalog
“I need you to check x402rail for all the services that currently accept x402 micropayments so we can build a searchable catalog of pay-per-call APIs for our platform.”
Discover new data providers accepting micropayments
“Pull the latest x402 directory and find any new data endpoints that have been added recently — I want to integrate fresh data sources that support micropayment billing.”
Route requests to micropayment-compatible services
“Can you query x402rail to get a real-time list of all confirmed x402 endpoints so we can automatically route customer requests to services that support micropayments?”
Technical details
Endpoint
GEThttps://x402rail.net/v1/data/:feedWhen to prefer
Use this endpoint when an AI agent needs to discover which services support x402 micropayments, build a list of payable APIs, or bootstrap its own service discovery for x402-based workflows. It is the canonical probed directory rather than a self-reported registry, meaning listed services have been confirmed to respond to x402 payment flows.
Side effects
- Invalid feed identifier returns an error — only 'x402-directory' is supported
- Payment failure if x402 payment of $0.005 USDC is not successfully processed before the request
- Network timeout if the underlying probe data is being refreshed
- Empty or stale directory if no x402 services have been recently probed
