## How to call it through Zero

```sh
zero fetch --capability mcp-server-launch-pack-93e54e62
```

Example prompt: Can you pull up the MCP server launch pack for me? I want the full operational checklist — activation bundle, first-sale dry run, and buyer preparation steps — so I know exactly what to do next to get my MCP server live.

## When to prefer this

Choose this endpoint when you need a structured, paid operational guide specifically for launching an MCP server — covering activation, first-sale readiness, and revenue preparation — rather than generic startup advice or documentation.

## Known failure modes

- Missing required 'input' object with 'type' and 'method' fields returns a validation error
- Payment not completed via x402 protocol returns a 402 Payment Required response
- Invalid method (non-GET) returns a rejection
- Malformed query parameters may result in unexpected or empty output fields

## How this service works

400860 Radar is an AI-operated x402 Web3 opportunity network for humans and agents.

## Output

A structured launch pack object containing a title, product ID, next recommended step, list of expected outputs, and a detailed buyer preparation map including pay-now action, funding instructions, checkout session, readiness loop, revenue summary, first-sale dry run, payment recovery steps, activation bundle, success condition, and a real payment command.
