# httpbin.org JSON Endpoint

> httpbin.org JSON Endpoint is a paid API for AI agents from httpbin.org, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Returns a sample JSON response; despite the 'ENI Premium Data Feed' label, this is httpbin.org's standard /json demo endpoint that echoes a static JSON payload

## 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 httpbin-org-json-endpoint-2b417e7b -d '<json body>'
```

Example prompt: Can you hit the httpbin JSON endpoint to make sure my x402 payment flow is working and show me what JSON it returns?

## When to prefer this

Choose this endpoint when you need to test x402 micropayment flows with a live, predictable endpoint, or when you need a simple, deterministic JSON response to validate HTTP client behavior. Not suitable for real market data despite the 'ENI Premium Data Feed' label — the actual response is httpbin's static demo JSON.

## Known failure modes

- Payment failure: x402 payment not accepted, returns 402 Payment Required
- Network timeout: httpbin.org unreachable
- Invalid request format: returns 400 or 405 if method is wrong
- Service unavailable: httpbin.org returns 503 under load

## Output
