Introduction
The RenderThink API transforms interior images: photorealistic rendering, editing, decoration and upscaling. You call it from your server, with an API key, and it responds in JSON.
| Route | Description |
|---|---|
POST /v1/renders | Photorealistic render of a draft image. |
POST /v1/edits | Edit by mask or by written instruction. |
POST /v1/decorations | Decoration of a furnished room, with accessories. |
POST /v1/upscales | ×2 or ×4 upscaling, without changing the content of the image. |
GET /v1/generations | Lists the organization's generations. |
GET /v1/generations/{id} | Retrieves a generation's state and result. |
POST /v1/generations/{id}/cancel | Cancels a generation that has not started. |
GET /v1/styles | Lists the decoration styles. |
GET /v1/edit-materials | Lists the materials for mask editing. |
GET /v1/edit-material-categories | Lists the categories of these materials. |
- Request and response bodies are JSON (UTF-8), with field names in
snake_case. - Every object states its type in the
objectfield:list,generation,style,edit_material,edit_material_category. - Dates are Unix timestamps, in seconds (UTC).
- A creation request responds when the generation ends, or as soon as it is accepted with
"background": true(see Generations). - Every response has a
request-idheader, and every error a stablecode(see Errors). - The API is called from a server only: it does not accept CORS requests, and a key must never be exposed in a browser (see Authentication).
- Quickstart: a first render, free of charge, with a test key.
- Pricing: prices per image, charged to a prepaid balance.
- Resolutions: the
1k,2k,4kand8koutput resolutions. - Full reference: every route, generated from the OpenAPI document.
- MCP server: the API from Claude Code, Codex, Cursor, VS Code, Gemini CLI or any other MCP-compatible agent.
