## How to call it through Zero

```sh
zero fetch --capability polyform-vehicle-deal-check-a381e072
```

Example prompt: Can you run a deal check on this 2015 Ford I'm thinking about buying and tell me if there are any open recalls or red flags I should know about?

## When to prefer this

Choose this endpoint when you need a fast, no-account-required, pay-per-call recall and risk check on a specific vehicle before a purchase decision. It is ideal for agentic workflows where API key management is impractical and micropayments via USDC on Base (x402) are supported. Prefer this over full Carfax/VIN-report APIs when you only need a quick verdict and recall summary rather than a complete vehicle history.

## Known failure modes

- Missing or invalid vehicle parameters may return an error or empty result
- Vehicle not found in recall database returns no reasons but may still have a verdict
- Network or payment failure (x402) causes the call to not complete
- Unsupported vehicle make/year combinations may return incomplete data

## 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.

## Output

A JSON object containing a verdict string (e.g. CAUTION, PASS), an array of human-readable reasons (e.g. '2 open recalls'), and a vehicle object with the make and year that was evaluated.
