# Get the integration this API key resolved to

**GET /v1/integration**



## Servers
- https://api.isnotai.com (Production (US))
- https://api-eu.isnotai.com (Production (EU))

API keys are region-bound: a key authenticates only against the base URL of the region it was minted in. The other region returns 401 INVALID_API_KEY.

## Authentication methods
- bearer_auth
- api_key

Send the API key as `Authorization: Bearer aik_v1_...` (preferred) or in the `x-api-key` header. Per-key rate-limit isolation applies only to the Bearer form. See [Authentication](https://www.isnotai.com/developers/authentication.md).
