## 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 uk-vehicle-emissions-lookup-f90b7f02 -d '<json body>'
```

Example prompt: What are the CO2 emissions, engine size, and fuel type for the UK car with registration plate AB12CDE?

## When to prefer this

Choose this endpoint when you need vehicle emissions, engine size, or fuel type data for a specific UK-registered vehicle by its number plate. It is distinct from the property-focused sibling endpoints on the same host and is the right choice for automotive, fleet, environmental compliance, or vehicle tax band queries — not for property price, rental yield, or stamp duty questions.

## Known failure modes

- Invalid or unrecognised registration plate returns an error or empty result
- Registration plate for a vehicle not in the DVLA database returns no data
- Malformed registration string (wrong format) may return a validation error
- Vehicles registered before emissions testing requirements may have no CO2 data
- Payment failure via x402 protocol results in 402 response and no data returned

## How this service works

Production API for UK sold prices, rental yields, and stamp duty. Paid via x402 protocol. Designed for AI agent consumption.

## Output

A JSON object containing the vehicle's CO2 emissions in g/km, engine displacement in cubic centimetres, fuel type (e.g. PETROL, DIESEL, ELECTRIC), and the registration plate as confirmed by the lookup.
