Replace example values with the user’s requested inputs, respecting the schema; do not execute an example merely to test a connection. ```json { "tool_id": "fal/fal-ai-hidream-i1-full", "input": { "prompt": "a cat holding a skateboard which has 'fal' written on it in red spray paint", "image_size": { "width": 1024, "height": 1024 }, "num_images": 1, "num_inference_steps": 50, "guidance_scale": 5, "negative_prompt": "", "enable_safety_checker": true, "loras": [], "output_format": "jpeg" } } ``` ## Execute and retrieve Inspect again before execution, explain the price and obtain the required authority. Use MCP run_tool or POST /v1/run with this tool ID, valid input and an idempotency key. Save the returned run ID and follow the actual state. If Agentik answers that the tool is temporarily unavailable, do not retry it blindly; use discovery to propose an alternative. This tool uses deferred settlement. Follow its returned task/run instructions; preserve the existing reservation until the result is reconciled. A partial or uncertain result can still have consumed provider resources. Consult [billing](/docs/billing.md), [idempotency](/docs/idempotency.md) and [asynchronous results](/docs/async.md).
