## 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 polyform-logistics-route-brief-api-15ccc39a
```

Example prompt: Give me a quick route brief for driving from Denver, CO to Salt Lake City, UT — I want to know if it's clear, how long it'll take, the distance, and a rough fuel cost estimate.

## When to prefer this

Choose this endpoint when you need a lightweight, instant route summary with a clear verdict, drive time, distance, and fuel cost — paid per call with no API key or account required. Ideal for AI agents making one-off logistics decisions or cost estimates without needing a full turn-by-turn navigation service.

## Known failure modes

- Missing or malformed query parameters may result in a 400 error
- Payment not received or insufficient USDC results in a 402 Payment Required response
- Unsupported route (e.g. non-drivable locations) may return an error or empty result
- Network timeouts if upstream routing data sources are unavailable

## How this service works

Pay-per-call data endpoints for AI agents. USDC on Base via x402. No account, no API key — one micropayment per call.
