Question 1

How do I authenticate with this API?

Accepted Answer

All requests go through the JoJ API gateway using your JoJ API key (X-JoJAPI-Key header). No separate account with MasterA AI is needed — subscribe to a plan and the gateway handles authentication to our backend automatically.

Question 2

Which models and GPUs power this API?

Accepted Answer

Requests run on our own NVIDIA RTX GPUs (5090, 5080, 4070 Ti Super) in the EU — no third-party cloud. Available models: Flux.1-Schnell and SDXL-Turbo for text-to-image, and LTX-Video / LTX-2 for text-to-video. Each request lands on whichever GPU has capacity, so there are no queues.
