Tripo API for Production-Ready 3D Models

The Tripo API is Tripo AI's interface for turning text prompts and single images into production-ready 3D models. On Atlas Cloud it powers the Tripo H3.1 Text-to-3D and Image-to-3D endpoints, each returning a textured mesh with PBR materials. You reach both through one Atlas Cloud API key with pay-as-you-go pricing.

From a single sentence or one reference image, Tripo generates game characters, mechanical parts, props, and product visuals as complete 3D meshes. Because the output ships with PBR textures, assets move straight into game engines, AR scenes, and 3D commerce pipelines without a manual rebuild.

Sign in to Atlas Cloud, create your API key, and send a prompt or image to the Tripo H3.1 endpoint through the same interface you use for other models. Generation runs asynchronously, and the response returns a downloadable GLB file once the model is ready. Start building today.

Both endpoints accept text descriptions or a single image, with the Text-to-3D model taking prompts up to 1024 characters. Results return as GLB, the glTF 2.0 based binary format that opens directly in Blender, Unity, Unreal Engine, and Three.js.

Tripo H3.1 Text-to-3D and Image-to-3D each cost $0.10 per generation on Atlas Cloud, and you are billed only for the calls you make. There are no subscriptions or seat fees, so spend scales directly with how much you generate.

Several parameters let you tune the result: PBR materials, texture quality set to standard or detailed, and geometry quality for finer surfaces. Quad mesh topology is available too when animation or sculpting workflows need clean edge loops rather than a triangle mesh.

Latency depends on the settings you choose, since detailed textures and higher geometry quality take longer than standard runs. Improved generation speed was one of the core upgrades in H3.1, and because requests process asynchronously your app can submit a job and poll for the finished model.

Rather than generating geometry token by token, H3.1 builds shapes natively in 3D probabilistic space, which keeps structure coherent and edges sharp. Against earlier releases it improves input alignment, geometry precision, and texture consistency, reducing the manual cleanup needed before assets reach production.
