## 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-gateway-4b926be1 -d '<json body>'
```

## When to prefer this

Choose this endpoint when you need a single, no-signup gateway to access a wide variety of AI agent tools and x402 services without managing individual API keys or wallets — ideal for agents that need to chain multiple capabilities or dynamically discover and call services paying per call in USDC.

## Known failure modes

- Invalid or unrecognized tool/service path returns 404
- Upstream x402 service unavailable returns 503
- Malformed request payload causes 400 bad request
- Payment facilitator timeout causes transaction failure
