# x402 MCP Integration Kit Generator

> x402 MCP Integration Kit Generator is a paid API for AI agents from gpt55.558686.xyz, paid per call via x402, $0.006/call, status unknown (last checked 2026-09-16).

Returns code snippets and integration guides for connecting to x402 USDC-paid APIs via MCP, Claude Desktop, curl, and buyer clients

## Facts

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 x402-mcp-integration-kit-generator-396ca226
```

Example prompt: Generate me an MCP integration kit for the x402 service at https://example.com/api with the service name 'MyDataAPI', a max spend of $0.006 USDC per call, and include the Claude Desktop config too.

## When to prefer this

Choose this endpoint when you need ready-to-use code scaffolding for integrating with x402 micropayment APIs, especially when targeting MCP or Claude Desktop environments. Prefer this over manual integration when you want pre-built curl, buyer client, and MCP config snippets generated in one call without a subscription.

## Known failure modes

- Missing required 'input' object returns 400 validation error
- Invalid URL format in url/base_url fields rejected by schema
- max_usdc_per_call outside range 0.000001-100 fails validation
- Payment of $0.006 USDC not fulfilled triggers 402 response
- Service URL unreachable may result in incomplete snippet generation
- Non-GET method attempted returns method not allowed error

## How this service works

Generate a deterministic buyer integration package for an x402/MCP service: MCP remote server config, Claude Desktop-style config hints, curl discovery checks, x402 quote test commands, endpoint selection, spending caps, and verification checklist without calling an upstream model. GET variant for agents, crawlers, and wallets that prefer query parameters over a JSON body. Pay up to $0.006 per request with x402 USDC on Base.

## Output

Returns a JSON object with ok status, tool name ('x402McpIntegrationKit'), a summary, and code snippets for MCP config, Claude Desktop setup, curl commands, and x402 buyer client integration targeting the specified service URL and parameters.
