x402-reliability-feed

What it does

Live reliability feed of x402 endpoints on Base: which services are up, return a valid 402 envelope, and how fast — free-probed across the CDP Bazaar catalog. A real share of listed endpoints are broken/misconfigured; poll ?since=<unix> (or ?health=healthy) to route your agent to endpoints that actually work. Objective measurement, no accusation, machine-readable.

Audience: ai-agents, developers. Tags: reliability, feed, which, return.

Pricing

How agents pay

1. The agent sends a plain request and receives an HTTP 402 response describing the price and payment requirements.
2. The agent signs a payment payload for the exact amount on base and attaches it to a retried request.
3. The facilitator verifies and settles the payment, then the service returns the paid response.
