## 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-crawler-monetization-kit-generator-get-4e741c68
```

Example prompt: Generate an x402 monetization kit for my documentation site at docs.myapi.io — call it 'MyAPI Docs', set the premium paths to /reference and /guides, keep /changelog free, price first access at $0.01, include the MCP payment flow and a Cloudflare worker config, and use Base network.

## When to prefer this

Use this endpoint when you need to scaffold an x402 payment-gating strategy for a content, docs, API, or MCP site without executing real payments or needing private keys. Prefer this GET variant when calling from an AI agent, crawler, or wallet that handles query parameters more naturally than a JSON request body. It is the right choice when you want a complete, ready-to-deploy monetization blueprint including edge configuration, MCP flow, and discovery assets in a single deterministic response.

## Known failure modes

- Missing required 'site_url' or 'site_type' query parameter returns a validation error
- Invalid price values outside allowed range (0.000001–1000) cause schema rejection
- Malformed URL in 'site_url' may result in an unparseable input error
- Network or gateway timeout returns a 5xx error with no kit generated
- Boolean flags passed as strings instead of true/false may cause parameter parsing failures

## How this service works

Generate a deterministic x402 monetization kit for content sites, documentation sites, API publishers, and MCP services that want AI crawlers or buyer agents to pay before accessing premium routes. Includes protected route tiers, discovery assets, robots/llms copy, Cloudflare-style edge notes, MCP/agent payment flow, spend caps, launch checklist, and conversion metrics without using private keys or making payments. GET variant for agents, crawlers, and wallets that prefer query parameters over a JSON body. Pay up to $0.019 per request with x402 USDC on Base.

## Output

A deterministic, structured monetization kit containing protected route tier definitions, discovery assets (robots.txt/llms.txt copy), Cloudflare-style edge worker notes, MCP/agent payment flow configuration, spend cap recommendations, a launch checklist, and conversion metrics — all scoped to the provided site and pricing parameters, returned as a JSON object without requiring private keys or live payments.
