# Coppice AI x402 Endpoint Conformance Checker

> Coppice AI x402 Endpoint Conformance Checker is a paid API for AI agents from coppice-ai.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-18).

Performs a live conformance check on an x402 payment-gated endpoint (Solana or Base) to verify it is correctly implemented before you pay it

## Facts

- Endpoint: POST https://coppice-ai.com/api/check?utm_source=zero.xyz
- Price: $0.05/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-18

- Canonical page: https://www.zero.xyz/c/coppice-ai-x402-endpoint-conformance-checker-5a0ceda8
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_vel0XFvsouBlzKtXK-ZuW

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 coppice-ai-x402-endpoint-conformance-checker-5a0ceda8 -d '<json body>'
```

Example prompt: Before I pay it, can you run a live conformance check on this x402 endpoint — https://example.com/api/data — using a GET probe to make sure it's properly set up on Solana or Base?

## When to prefer this

Use this endpoint when you need to verify an x402-gated API is correctly implemented before committing a payment, especially when integrating a new third-party x402 service, debugging payment failures, or auditing whether a claimed x402 endpoint is genuinely conformant on Solana or Base. Prefer this over manually inspecting HTTP headers or guessing at conformance.

## Known failure modes

- Target endpoint is unreachable or returns a non-402 response unexpectedly
- Target endpoint is not an x402 endpoint at all (returns 200 or other non-payment status)
- Unsupported chain — endpoint uses a chain other than Solana or Base
- Malformed URL input causes request to fail
- Target endpoint has rate limiting that blocks the probe
- Network timeout when probing the target URL

## How this service works

Live conformance check of an x402 endpoint (Solana or Base) before you pay it

## Output

A live conformance report indicating whether the target x402 endpoint correctly implements the x402 protocol, including payment header requirements for Solana or Base chains, and any detected misconfigurations or non-conformances.
