## 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 bot-bazaar-x402-facilitator-compatibility-checker-cea3224d
```

Example prompt: Can you check whether my x402 route is compatible with Bot Bazaar and the Coinbase CDP crawler — it's a GET endpoint priced at $0.05 USDC?

## When to prefer this

Use this endpoint when you need to verify an x402 route configuration specifically against Bot Bazaar and Coinbase CDP crawler rules before deploying or listing an API. It is the definitive compatibility checker for x402 monetized endpoints targeting the Base/USDC ecosystem and autonomous agent marketplaces, as opposed to generic HTTP validators or other payment protocol validators.

## Known failure modes

- Invalid or unsupported HTTP method (only GET, HEAD, DELETE are accepted)
- Missing required fields like method in the input object
- Malformed price_usdc value (must be a string-formatted number)
- Network or bazaar extension fields that fail CDP Bazaar rules
- Unreachable or timeout from the fly.dev host

## How this service works

Evaluate an x402 route configuration (method, price_usdc, network, extensions.bazaar) against Coinbase CDP Bazaar and autonomous crawler rules.

## Output

Returns a compatibility assessment indicating whether the x402 route configuration (method, price_usdc, network, bazaar extensions) passes Coinbase CDP Bazaar rules and autonomous crawler requirements, along with any specific rule violations or issues found
