API key authentication

Send the assigned API key in the X-API-Key request header for every protected request:
Utexo rejects requests with a missing or invalid API key.
Examples use BASE_URL_PLACEHOLDER. Obtain the environment-specific API base URL and API key from the Utexo team before integration. The base URL includes the /v1 version prefix.

Request requirements

Include X-API-Key on every protected endpoint. Utexo rejects requests with a missing or invalid key. Do not expose the API key in client-side applications or public repositories.
