# TTAPI

> TTAPI is a unified AI API gateway for image, video, music and audio, and language models. Developers use one API key and one balance across supported services.

Start with the quick start for integration, or browse the model entries below for capabilities, examples, and links to API references. Follow each endpoint's documentation for authentication, request parameters, and response formats.

Where shown, Model ID is the model value in the endpoint's request example. Other services use dedicated endpoints or product-specific fields documented in their API references.

For current model availability, API parameters, and billing rules, consult the official documentation and dashboard before integrating.
