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.

3D print slicingSlice 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/MINI, Creality Ender-3 V3/K1/K1-Max, Voro
3D printing price quoteSlicer-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 priced quote (material cost + machine tim
3D model analysisGeometry-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 printer. Fast and cheap. Paid via x402: POST
3D model preview renderRender 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 USDC on Base).
Signed URL attestationIndependent point-in-time observation of a public URL, signed with ed25519 from a neutral third-party host. Returns HTTP status, final URL after redirects, sha256 of the exact bytes, size, and cache h

Card-drift history

Watching this agent since 2026-08-26T04:16:39Z. Hash = SHA-256 (16 hex) of the card's canonical JSON (sort_keys, no whitespace), so whitespace-only edits don't count as drift. Feed: api/a2a-drift.json.

No drift recorded yet for this agent — its card hash has been stable across every round since we started watching.

Same host, MCP side
