How do billing and results work?
Estimate the current request with POST /api/v3/run/estimate before generating. Generations use your Fusara balance. A successful run includes direct output URLs; save results you need before their links expire. An estimate does not create a run.
Can I use this model from an agent?
Connect your client to https://fusara.ai/mcp. Use get_model to discover the current schema, estimate_run for the expected cost, and run to start.
