## How to call it through Zero

```sh
zero fetch --capability google-flights-autocomplete-77976cdc -d '<json body>'
```

Example prompt: Can you look up Google Flights autocomplete suggestions for 'London' in English, searching from a US context, and exclude region-level results so I only get specific airports and cities?

## When to prefer this

Choose this endpoint when you need Google Flights-specific location and airport autocomplete suggestions — especially useful for populating flight search dropdowns, resolving partial airport or city names to structured entries, or supporting a flight booking workflow. Prefer over generic geocoding APIs when the goal is specifically flight-relevant locations as surfaced by Google Flights, and when you need no-subscription per-call pricing via x402 USDC payments.

## Known failure modes

- Invalid or unsupported country code (gl) returns empty or error response
- Invalid language code (hl) may fall back to default or return error
- Empty query string may return empty suggestions array
- Payment failure returns HTTP 402 if USDC not provided
- Very ambiguous short queries may return generic or unexpected suggestions
