Using it via the API
Once AxForge deploys seedvr2-comfyui for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (seedvr2-comfyui below is illustrative; you get the exact model name on deployment.)
$ curl -sS https://api.axforge.ai/v1/videos/generations \
-H "Authorization: Bearer $AXFORGE_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"seedvr2-comfyui","prompt":"a drone shot over a forest"}'
