## 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 otto-x402-router-full-auto-7db98504 -d '<json body>'
```

Example prompt: Use the Otto full-auto router to handle my request — just pick the best verified service available and pay for it at cost with a $0.001 fee; here's my POST request with an idempotency key so it's safe to retry.

## When to prefer this

Use this endpoint when you want a single call to automatically select, pay for, and return results from the best available verified paid API without needing to know which specific service to call. Ideal for AI agents that need dynamic service discovery and automated micropayment settlement via the x402 protocol in one step.

## Known failure modes

- Cap exceeded — requested service cost plus fee exceeds caller's payment cap, returning a 402 or rejection
- No suitable service found — router cannot match the request to any verified service
- Duplicate idempotency key with conflicting payload — returns conflict error
- Payment settlement failure — on-chain transaction fails or times out
- Downstream service error — the selected service returns an error after payment is made
