## 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 quartermaster-x402-router-76d35d00
```

Example prompt: Use Quartermaster's router to figure out if 0x1234abcd5678ef90 is a contract on Base — just send the goal as a plain-English question and let it pick the right tool.

## When to prefer this

Use this endpoint when you don't know which specific Quartermaster tool to call, or when you want a single unified entry point for any x402, Base blockchain, crypto-price, or web/AI task. Ideal for agents that need to handle diverse user queries without hardcoding per-tool routing logic.

## Known failure modes

- Ambiguous or unrecognizable goal in q results in no tool match and an error response
- Goal references an unsupported domain outside x402/crypto/web toolkit
- Network or upstream tool failure returns an error indicating which sub-tool failed
- Malformed query string or missing q parameter returns a 400-level validation error
- Payment not completed results in 402 Payment Required response

## How this service works

The x402 Router: send a plain-English goal in q (e.g. 'audit https://api.example.com/paid', 'price of eth', 'is 0x… a contract', 'verify settlement 0x…') and Quartermaster picks the right tool from its full toolkit, runs it, and returns the answer plus which tool it used. One endpoint for anything x402, crypto-on-Base, or web/AI.

## Output

Returns the answer to the requested goal along with metadata indicating which underlying tool was selected and executed, in structured JSON.
