# Google Flights API
The Google Flights API provides real-time access to structured flight search results, enabling users to find flights based on various criteria.
## Get Your API Key
Sign in at [hasdata.com](https://app.hasdata.com/sign-in), go to your account settings, and copy your API key.
All requests must include your key in the `x-api-key` header.
## Request Cost and API Credits
Each request to the Google Flights API consumes **API Credits** from your account balance.
* **Cost per request:** 15 API Credits
* Credits are deducted only for successful requests.
* Your total available credits depend on your active plan.
You can use your credits across all HasData APIs. The same credit balance is shared platform-wide.
**Unused credits do not roll over.** Any remaining credits expire at the end of the current billing period.
To monitor your credit usage and remaining balance, sign in to your account dashboard at [app.hasdata.com](https://app.hasdata.com/sign-in).
