CSM (Common Sense Machines) APICreate 3D assets and multi-part kits from images via async REST sessions (image-to-3D, retopology).API key
API key created from Cube webapp user profile, sent as bearer/header token		—Unavailable: service appears discontinued—Async session-based API; monitor completion via webhook (recommended) or polling. The vendor's Blender MCP repo (github.com/CommonSenseMachines/blender-mcp) now returns 404; no maintained MCP server found.—
Hyper3D Rodin APIGenerate 3D meshes from text or images (sketch/regular/detail quality tiers) via an async REST job API.API key
Authorization: Bearer <RODIN_API_KEY>		—Paid only: API access requires the Business plan ($120/mo, $96/mo billed annually) or Enterprise; direct credits $1.5 eachBase URL: https://api.hyper3d.com/api/v2
Free plan: none ↗
Async jobs: POST /rodin returns uuid + jobs.subscription_key; poll POST /status, then POST /download with task_uuid ↗		Async task-based API: submit generation, then poll or use webhooks to retrieve the finished asset.—
Meshy APIGenerate, retexture, rig, and animate 3D models from text or images via REST API or official MCP server.API key
Authorization: Bearer <msy-...>		officialPaid only: creating API keys requires a paid plan (Pro $20/mo+); Free accounts get only a built-in test key for the Playground (free web plan 100 credits/mo)Base URL: https://api.meshy.ai/openapi/v1
Free plan: none ↗
Rate limits: 20 requests/s on Pro-Ultra (Enterprise 100); concurrent queue tasks 10 (Pro) to 100 (Ultra); 429 when exceeded ↗
Data policy: Generated files retained for 3 days on non-Enterprise plans ↗
Async jobs: POST returns task id; poll GET task until SUCCEEDED, or use SSE streaming or webhooks ↗
MCP tools: 24: meshy_text_to_3d, meshy_text_to_3d_refine, meshy_image_to_3d, meshy_multi_image_to_3d, meshy_creative_lab, meshy_remesh … ↗		Free web accounts get only a limited built-in Playground key; creating/managing your own API keys requires a paid subscription.GitHub 48★ meshy-dev/meshy-mcp-server
Sketchfab Data APISearch, download, and upload 3D models on Sketchfab programmatically via the REST Data API v3.API key / OAuth
Authorization: Token <API_TOKEN> (personal token) or OAuth2 Authorization: Bearer <access_token>; legacy v2 endpoints are deprecated		communityFree: no key needed for search and model listing (GET /v3/search, /v3/models); downloads (/v3/models/{uid}/download) need a free account tokenBase URL: https://api.sketchfab.com/v3
Free plan: free_tier ↗
Rate limits: Calls can be throttled to limit abuse; throttled clients get 429 Too Many Requests (no numeric limit published) ↗
Example call: search 3D models: GET https://api.sketchfab.com/v3/search?type=models&q={keywords} ↗
MCP tools: 3: sketchfab-search, sketchfab-model-details, sketchfab-download ↗		This is an asset hosting/marketplace API, not a generative AI model; downloading models generally requires an authenticated Sketchfab account (and often the uploader's permission/license). Use v3 endpoints; v2 is deprecated.GitHub 40★ gregkop/sketchfab-mcp-server
Stability AI 3D (Stable Fast 3D / SPAR3D) APIConvert a single 2D image into a textured 3D mesh (GLB) via the v2beta/3d REST endpoints.API key
