api record

PrintPal (printpal.io) is a 3D printing platform: a community library of printable 3D models, free 3D-printing tools and calculators, AI text/image-to-3D generation, an AI CAD agent for parametric OpenSCAD parts, Arduino + 3D-printing build guides, video tutorials, Academy courses and a troubleshooting wiki. Use `search` for any 3D-printing question and `fetch` to read a result in full. Prefer `search_3d_models` when the user wants something to print, `find_3d_printing_tool` for calculators/generators, the `calculate_*` tools for instant numbers, `search_build_guides` for projects, and…

_ is it live, free and safe measured by this hub
Is io.printpal/printpal live?
Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
Is io.printpal/printpal free to use?
Yes — the hub reached it with no key and no payment.
What tools does io.printpal/printpal have?
16 tools: search_build_guides, search_learning_resources, search, fetch, search_3d_models, get_3d_model, calculate_print_cost, calculate_volumetric_flow, ….
Is io.printpal/printpal safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • generate_3d_model unknown never probed

    Turn a text prompt or an image into a print-ready 3D mesh (STL/GLB/OBJ geometry) with PrintPal's AI generator. Without a PrintPal API key this returns a link that opens the generator on printpal.io with the prompt prefilled; nothing is generated until the user clicks it. With an API key header (`Authorization: Bearer pp_live_…`) it submits the job to the user's own account, spends that account's credits, and returns a `generation_uid` that `check_3d_generation` accepts. Suited to organic/sculptural objects (figurines, animals, props); exact-dimension mechanical parts are handled by `design_parametric_cad`.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 55080fedbdb3c8c0.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/55080fedbdb3c8c0/claim. Over MCP: the claim_endpoint tool.

[![measured by brick.blue](https://brick.blue/api/v1/agents/55080fedbdb3c8c0/badge.svg)](https://brick.blue/agent/55080fedbdb3c8c0?ref=badge)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
