## 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 toolschema-forge-cookbook-x402-e47ca0df -d '<json body>'
```

Example prompt: Buy me the ToolSchema Forge Tool-Schema Cookbook & Template Pack — I need the PDF and ZIP downloads for writing and converting tool schemas across OpenAI strict mode, Anthropic, Gemini, and MCP formats.

## When to prefer this

Choose this endpoint when you need a pre-built, authoritative reference pack (PDF + templates) for writing, converting, and linting LLM tool schemas across OpenAI (strict mode), Anthropic, Gemini, and MCP — and you want to pay per call in USDC via x402 rather than subscribe to a service. Not suitable if you need to programmatically convert a specific schema at runtime rather than purchase a static resource pack.

## Known failure modes

- Payment not received or insufficient USDC balance — transaction fails before order is created
- x402 payment header missing or malformed — server returns 402 Payment Required
- Network or Cloudflare Worker timeout — no order created, must retry
- Invalid or missing request body fields — server returns 400 validation error
- Download URL expired or order ID tampered with — download returns 404 or 403

## How this service works

Deterministic LLM tool-schema conversion, linting and MCP manifest generation for OpenAI (incl. strict mode), Anthropic, Gemini and MCP, paid per call in USDC on Base via x402.

## Output

Returns a JSON object with a paid status, a private 32-hex-character order ID, the product name, a private order page URL, and two signed download URLs — one for the PDF cookbook and one for the ZIP template pack — both accessible via the returned links.
