Higgsfield now has an API you can connect directly to Codex, giving you access to video and image models with usage-based pricing.
In this video, I walk through creating the API key, storing it safely in your .env file, running a first generation, and using a free Codex skill to handle model settings and cost tracking. I also compare outputs and prices across Seedance, Kling, and MiniMax so you can see why testing the same prompt across models matters.
