FAQ
Developer FAQ
Common questions about integrating with the Lyndium API.
Sign up for a Lyndium account and choose the Developer plan. Your API key will be provided upon signup. Use it in the x-api-key header with every request.
Most generation endpoints return a job ID immediately. You then poll the corresponding status endpoint until the job completes. Status values include pending, processing, succeeded, and failed. We recommend polling every 3-5 seconds.
For images: OpenAI, ModelsLab, and 4K models. For video: LTX Video, Amazon Nova, Seedance 2.0, and Veo 3.1 Lite. For faceless video scenes: OpenAI, Stability AI (SD 3.5, SD 3.5 Large, SD 3.5 Large Turbo), Amazon Nova Canvas, and Titan Image.
Faceless video voice-over supports 14 languages: English, Spanish, French, German, Italian, Portuguese, Russian, Japanese, Korean, Chinese, Arabic, Hindi, Turkish, and Dutch. Both male and female voice options are available for each language.
API usage consumes the same credits as the web interface. Your credit balance is shared across both the UI and the API. Premium plans provide more credits and higher rate limits.
