## 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 7it-solutions-7maps-x402-preflight-check-5f04ef6c -d '<json body>'
```

Example prompt: Before calling the 'search_web' tool on the registry at https://mcp.example.com, do an x402 preflight check to see what payment is required — pass empty arguments for now.

## When to prefer this

Use this endpoint when you need to discover x402 payment requirements for an MCP tool call before committing to payment — ideal for agent workflows that gate tool execution on cost checks, or when building payment-aware orchestration layers that need to validate pricing before spending USDC.

## Known failure modes

- Unknown tool name returns an error or empty preflight response
- Invalid server URL causes connection failure or 402 rejection
- Malformed arguments object may result in validation error
- Server does not support x402 protocol, returning unexpected response format
- Network timeout if the target server is unreachable

Returns a JSON response containing x402 payment preflight details such as required payment amount, accepted currency, payment channel information, and any authorization metadata needed to proceed with the actual tool call.
