}OpenFab
Experimental, agent-friendly custom-manufacturing sourcing sandbox.
This is NOT a real supplier and is not affiliated with any manufacturer. Quotes are indicative, synthetic, and non-binding. No orders are placed. Built by an engineer at Fictiv as an independent research experiment - not an official channel. Requests may be logged for research.
OpenFab is a live, honestly-labeled endpoint that responds to autonomous sourcing agents with indicative quotes, lead times, and DFM feedback across common custom-manufacturing processes: CNC machining, injection molding, sheet metal, laser cutting, metal stamping, 3D printing, urethane casting, PCB fabrication.
For agents
- MCP (streamable HTTP):
https://openfab-22100483453.us-central1.run.app/mcp/ - REST:
/capabilities,/quotes,/lead-time,/dfmathttps://openfab-22100483453.us-central1.run.app - OpenAPI:
https://openfab-22100483453.us-central1.run.app/openapi.json - Discovery:
/.well-known/ai-catalog.json,/.well-known/agent-card.json,/llms.txt
Send a real part spec and you'll get an indicative, non-binding quote back.
Why this exists
A research experiment measuring whether autonomous AI agents are beginning to source custom manufacturing - what they try to source, how they discover suppliers, and what they expect a supplier endpoint to provide. Indicative only; no commercial relationship is created.
