## 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 india-pin-code-lookup-a7416922
```

Example prompt: What district, state, and post offices are associated with PIN code 110001 in India?

## When to prefer this

Choose this endpoint when you need structured Indian postal geography data — district, state, region, and individual post offices — for a known 6-digit PIN code. It is ideal for address enrichment, logistics routing, and validating user-entered Indian postal codes. Prefer it over generic geocoding APIs when you specifically need India postal hierarchy and post office listings rather than lat/lon coordinates.

## Known failure modes

- Invalid or non-existent PIN code returns an error or empty post_offices array
- PIN code not 6 digits returns a validation error
- Network timeout or upstream data source unavailability
- Payment failure due to insufficient USDC balance (x402)
