## 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-property-energy-performance-certificate-lookup-4ce28026
```

Example prompt: Can you pull up the energy performance certificate data for the postcode E1 6AN — I want to know what EPC bands the properties there have and what share are rated C or better?

## When to prefer this

Choose this endpoint when you need official UK government EPC data for a specific postcode without requiring API key signup — ideal for agents that need pay-per-use property energy data in USDC via x402, real estate research tools, compliance checks, or sustainability analysis pipelines where occasional lookups don't justify a subscription.

## Known failure modes

- Invalid or malformed postcode returns an error or empty result
- Postcode with no registered EPC certificates returns count of 0 and empty arrays
- Very rural postcodes may have sparse or no data
- Payment failure via x402 protocol prevents data retrieval
- Rate limiting or temporary upstream EPC register unavailability

## How this service works

Pay-per-call UK company, property and crypto market data for AI agents via x402. Official sources, no signup, no API keys, failed calls never charged.

## Output

A JSON object containing the queried postcode, total certificate count, local council name, an array of individual EPC certificates (each with address, band, registration date, and certificate number), a band distribution map (e.g. {A: 3, B: 12, C: 45}), and the share of properties rated band C or better as a decimal fraction.
