# FabTally

> Pay-per-call fabrication utilities for AI agents. Give it a 3D model (STL/3MF/OBJ/STEP/PLY) and get a real, slicer-accurate slice on any of 12 calibrated FDM printers: print time, filament grams/metres, layer count, sliced g-code, a PNG preview render, model geometry, and a priced quote. Also offers signed point-in-time URL attestations. Machine-payable over x402 (USDC on Base, eip155:8453) with a free discovery document; no account, no API key. Free discovery: https://fabtally.com/agent/overview and https://fabtally.com/openapi.json .

## Skills
- **3D print slicing** — Slice an uploaded 3D model (STL/3MF/OBJ/PLY/STEP) with our production slicing engine on any of 12 calibrated FDM printers (Bambu A1/A1-mini/P1S/X1C, Prusa MK4/M
- **3D printing price quote** — Slicer-accurate FDM 3D-printing price quote (not an estimate). Upload a 3D model and optional material and quantity; returns print time, filament grams, and a p
- **3D model analysis** — Geometry-only analysis of a 3D model with no slice: bounding box (mm), volume (cm3), triangle count, watertight flag, and a fits-on-bed check for a chosen print
- **3D model preview render** — Render a base64-encoded PNG preview of an uploaded 3D model (matplotlib, headless, no slice). Paid via x402: POST https://fabtally.com/agent/v1/preview ($0.005 
- **Signed URL attestation** — Independent point-in-time observation of a public URL, signed with ed25519 from a neutral third-party host. Returns HTTP status, final URL after redirects, sha2
