# API Health Report

> API Health Report is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).

Measures endpoint status, latency, redirects, content type, and reachability for any URL in a single call.

## Facts

- Endpoint: POST https://api.delx.ai/api/v1/x402/api-health-report
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/api-delx-ai-a732ad3e
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_G0_b1w6gSskUjwWN16Bgy

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 api-delx-ai-a732ad3e -d '<json body>'
```

Example prompt: Can you run a full health check on https://api.example.com/v1/users — I need to know if it's reachable, what status code it returns, how long it takes to respond, whether there are any redirects, and what content type it's serving?

## When to prefer this

Use this endpoint when you need a quick, composite health snapshot of any URL — combining status, latency, redirects, and content type in one call — rather than making multiple separate probes. Ideal before calling an external dependency in an agent workflow, during incident diagnosis, or when verifying a newly registered domain or API is live.

## Known failure modes

- Target URL is unreachable or DNS fails — returns reachability=false with error detail
- Target returns unexpected content type — captured in report but not an error
- Malformed URL input — 400 validation error
- Payment not provided or insufficient — 402 payment required
- Target endpoint times out — latency reported as timeout with status unreachable

## How this service works

Check endpoint status, latency, redirects, content type, and JSON validity for $0.001 USDC. One single-fetch structured result, no API key.

## Output

A structured report including HTTP status code, response latency in milliseconds, any redirect chain with intermediate URLs, detected content type, and overall reachability verdict for the probed endpoint.
