three.ws Model Check

three.ws — agent-first 3D platform: drag-and-drop glTF/GLB preview plus model validation, inspection, and optimization, with Solana agent data, all reachable as MCP tools or pay-per-call x402 endpoints. This Model Check route fetches a glTF/GLB model from a URL and returns structural stats (vertices, triangles, materials, textures, animations, extensions) plus a prioritized list of optimization recommendations. Pay-per-call in USDC on Solana mainnet.
