# x402 Endpoint Reliability Feed

> x402 Endpoint Reliability Feed is a paid API for AI agents from x402.dailyelo.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Returns a live reliability feed of x402 endpoints on Base, including reachability status, valid-402 envelope checks, and latency measurements across the CDP Bazaar catalog.

## Facts

- Endpoint: GET https://x402.dailyelo.com/v1/reliability/recent
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/x402-endpoint-reliability-feed-4640731a
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_eJgROmV75zKgVN02Lx3Vg

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability x402-endpoint-reliability-feed-4640731a
```

Example prompt: Show me which x402 endpoints on Base are currently healthy and responding correctly — only return ones checked in the last hour, up to 50 results.

## When to prefer this

Use this endpoint when you need to route an AI agent to x402 services that are actually operational, or when auditing the health of the CDP Bazaar x402 catalog. Prefer this over manual probing when you need a pre-aggregated, machine-readable reliability snapshot across many endpoints at once.

## Known failure modes

- No records found for the requested time window (empty result set if 'since' timestamp is too recent)
- Invalid 'health' filter value returns 400 or empty results
- 'limit' exceeding 1000 may be clamped or rejected
- Service itself may be temporarily unavailable, returning 5xx
- Payment of 0.005 USDC required; missing or invalid payment header returns 402

## How this service works

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.

## Output

A list of reliability records for x402 endpoints, each including the endpoint URL, health status (healthy/misconfigured/down), whether it returned a valid 402 envelope, measured latency, and the timestamp of the last probe. Results can be filtered by health state and recency.
