AFN API documentation

One funnel for every fabrication process: quote → refine → checkout → track. Live processes: fdm_print and resin_print (3D printing), cnc, sheetmetal, laser_cut, decal (custom stickers), print (paper — cards, flyers, posters), and apparel, US shipping. AFN speaks UFP — the Universal Fabrication Protocol. The canonical schema reference is the protocol spec; the machine-readable version is openapi.json.

For fdm_print: spec.file_id is an STL or STEP (converted server-side); optional material (pla|petg|asa), color, quantities.

For print: spec.file_id is print-ready artwork (PDF preferred, PNG/JPEG accepted); optional product (business_cards|flyers|posters — omit to quote every kind the artwork fits), free-form size ("letter", "24x36"), free-form paper ("matte", "glossy", "recycled"), sides (single|double), quantities. Deadline, budget, and durability constraints filter print offers like any other process; product kinds, sizes, and stocks are discoverable via GET /v1/capabilities.

For sheetmetal: spec.file_id is a DXF flat pattern or STEP model; free-form material (canonical mild_steel|aluminum_5052|stainless_304 — "steel", "5052", "stainless" resolve), optional thickness_in (quoted at the nearest stocked gauge), optional units (mm|in, DXF only, default mm), optional bend_count (> 0 prices CNC bending), free-form finish (as_cut default, deburred, powder_coat), quantities. Filterable criteria: outdoor_rated drops bare mild steel (it rusts) while aluminum/stainless pass — and upgrades unpinned mild steel to a protective powder_coat finish; submersible matches nothing (no vendor claim); deadline and budget narrow as usual. Material attributes, per-material thicknesses_in, and finishes are discoverable via GET /v1/capabilities.

Auto-routing

Omit process and AFN detects the file kind — artwork (png/jpg/svg/pdf), stl, step, dxf — and quotes every process that can make it, fanning out over a small default material set per process. The response adds a routing object: {detected_file_kind, candidates, also_possible, viewer_mesh_url}. also_possible lists processes AFN can't quote yet (e.g. pcb) with a reason; each is logged as a demand signal that drives vendor sourcing. viewer_mesh_url (mesh/BREP uploads only) serves a face-classified binary viewer mesh (AFVM v1) that derives lazily — poll it until 200. Passing process explicitly behaves exactly as before.

Checkout

POST /v1/checkout
{
  "offer_id": "of_...",
  "shipping_option_id": "express",          // from the offer's shipping_options
  "ship_to": { "name": "...", "street1": "...", "city": "...", "state": "TX", "zip": "78701" },
  "contact": { "email": "buyer@example.com" },
  "coupon_code": "AFN-XXXXXX"               // optional — only if the user gave you one
}
# → { "order_id": "ord_...", "checkout_url": "https://checkout.stripe.com/...", "total_cents": 4230 }

Hand checkout_url to your user — never collect card details yourself. AFN is the merchant of record and places the vendor order automatically after payment. Lifecycle: pending_payment → paid → placing → placed → in_production → shipped → delivered.

Connect your agent (MCP)

AFN speaks standard MCP over Streamable HTTP — one endpoint serves ChatGPT, Claude, Gemini, Cursor, Copilot, and every other MCP client. Tools: get_fabrication_quote, refine_quote, create_checkout, get_order_status, list_orders, leave_review. ChatGPT additionally renders an embedded offer-comparison widget; every other client gets the same results as complete text.
