“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 .

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of fabtally.com controls every word below.

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/MINI, Creality Ender-3 V3/K1/K1-Max, Voron 2.4 350, Anycubic Kobra 2, Elegoo Neptune 4 Max). Returns print time, filament grams and metres, layer count, model geometry and fits-on-bed; tiers add a PNG preview and/or the sliced g-code (gzip+base64). Choose printer, material (pla, pla-cf, petg, petg-cf, abs, abs-cf, asa, asa-cf, nylon, pc, pet, tpu), quality (draft/standard/fine) or explicit layer_height, infill_percent, and supports (auto/none/tree). Paid via x402: POST https://fabtally.com/agent/v1/slice ($0.005 USDC), /v1/slice/preview ($0.01), /v1/slice/gcode ($0.015), /v1/slice/full ($0.02).

Examples it gives
  • Slice this STL on a Bambu X1C in PETG at 0.20mm and tell me the print time and filament use.
  • Give me the g-code for this bracket on a Prusa MK4 with tree supports and 20% infill.

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 priced quote (material cost + machine time + setup fee, with automatic volume discounts). Paid via x402: POST https://fabtally.com/agent/v1/quote ($0.005 USDC on Base).

quotepricing3d-printingmanufacturingcost-estimatex402
Examples it gives
  • How much would 25 of these brackets cost to 3D print in PLA?
  • Quote this STL in ABS.

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 printer. Fast and cheap. Paid via x402: POST https://fabtally.com/agent/v1/analyze ($0.002 USDC on Base).

geometrymeshanalysis3d-modelbounding-boxx402
Examples it gives
  • What is the bounding box and volume of this STL, and is it watertight?
  • Will this model fit on an Ender-3 V3 bed?

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 USDC on Base).

renderpreviewpng3d-modelvisualizationx402
Examples it gives
  • Show me a preview image of this STL.

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, sha256 of the exact bytes, size, and cache headers, plus your chosen check (exists / contains a string / content hash). A verifiable record that a page said something at a specific moment. Free schema and verification key at GET https://fabtally.com/agent/v1/attest/schema . Paid via x402: POST https://fabtally.com/agent/v1/attest ($0.01 USDC on Base).

attestationurled25519witnessverificationx402
Examples it gives
  • Attest that https://example.com/pricing currently contains the string "$49/mo".
  • Give me a signed sha256 of what https://example.com/robots.txt returns right now.
