How it works

Three steps from workflow to production API.

01
Define
Write your workflow as a JSON spec. Define inputs, steps, and provider integrations.
→
02
Publish
Deploy to InvokeFast. Instantly get a REST endpoint and MCP tool.
→
03
Invoke
Any AI agent calls it. Deterministic execution, every time. Results via API.

One API call. That’s it.

Start a workflow run with a single POST request.

bash REST API
# Start a workflow run curl -X POST https://invokefast.com/api/v1/workflows/photo-to-video/runs \ -H "x-api-key: sk_live_..." \ -H "Content-Type: application/json" \ -d '{ "image_url": "https://example.com/photo.jpg", "prompt": "slow cinematic zoom, golden hour" }' # Response { "id": "run_8x7k2m", "status": "running", "workflow": "photo-to-video" }
