## 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 postcode-context-uk-single-postcode-socio-economic-profile-88794fe2
```

Example prompt: Can you pull up the full socio-economic profile for postcode SW1A 2AA — I want to see the deprivation decile, census demographics, average house prices, £/sqm, EPC ratings, and broadband speeds for that area?

## When to prefer this

Use this endpoint when you need a deep, multi-dimensional socio-economic snapshot of a specific UK postcode in a single call, combining property prices, deprivation indices, census demographics, energy ratings, and broadband in one response. Prefer it over generic postcode-to-coordinates lookups or simple address validators when the goal is neighbourhood intelligence, property analysis, or social research. For bulk enrichment of many postcodes at once, prefer the batch endpoint.

## Known failure modes

- Invalid or malformed postcode returns a 400 or 404 error
- Postcode exists but has no associated data (e.g. very new or non-residential postcodes) may return empty or partial fields
- Network timeout or service unavailability returns 5xx
- Payment failure via x402 protocol blocks the request
