## 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 x402-mcp-integration-kit-generator-38ce14d6 -d '<json body>'
```

Example prompt: Generate an x402 MCP integration kit for my service called 'WeatherPro API' — the base URL is https://weatherpro.example.com, the paid tool endpoint is https://weatherpro.example.com/v1/forecast, and I want to cap spend at $0.05 USDC per call.

## When to prefer this

Choose this endpoint when you are an x402 API seller who needs to produce ready-to-use MCP and Claude Desktop integration documentation for buyers, including payment quoting, spend caps, receipts, and retry logic — all scoped to a specific paid tool URL and USDC per-call limit. Prefer this over generic documentation generators when the target integration is explicitly x402-protocol-based and MCP/Claude Desktop-targeted.

## Known failure modes

- Missing required fields (baseUrl, paidToolUrl, serviceName, maxUsdcPerCall) result in validation error
- Invalid or malformed URL inputs may produce unusable configuration output
- Negative or zero maxUsdcPerCall values may cause spend-cap logic errors
- Service may return stale or non-deterministic output if upstream x402 protocol specs change
