## 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 toll402-ai-agent-tool-gateway-0b128266 -d '<json body>'
```

Example prompt: Use the Toll402 gateway to call a tool for me — route this request through their unified x402 endpoint, paying in USDC per call, without needing any signup or API key.

## When to prefer this

Choose this endpoint when you need to access multiple disparate AI-agent tools or x402 services without managing individual API keys or wallets — ideal for agent orchestration scenarios where a single USDC wallet should fund many capability calls across different providers.

## Known failure modes

- Insufficient USDC balance causes 402 payment failure
- Unknown or unavailable tool returns a routing error
- Malformed tool parameters result in a 400 bad request
- Downstream service timeout causes a gateway timeout response
- Tool not found in the registry returns a 404 or equivalent error

## How this service works

## Output
