A new home on Comfy. For supported endpoints, switch the base URL and API key. Keep your request paths, parameters, and response handling. Check your endpoints before changing your integration. PREPARE YOUR SWITCH [CREATE API KEY](https://platform.comfy.org/profile/api-keys) Not every existing Stability AI route is supported. View endpoint list THE TRANSITION ## Keep your integration. Change the URL and key. Stability AI’s Image Services and 3D APIs are now available on Comfy. Check the endpoint list below first. Compatibility depends on the route and parameters your application uses. ### IMAGE SERVICES Generate with Stable Image Core, Ultra, SD3.5, and SDXL. Edit with Inpaint, Outpaint, Erase, Search and Replace, Search and Recolor, and Remove Background. Control composition and style, or upscale an image. ### 3D APIS Stable Fast 3D and Stable Point Aware 3D routes are supported. Review the reference below. ## Prepare in two steps. Get your Comfy account ready, then review the URL and authentication changes. 1. 01 ### Create your Comfy API key Use the Comfy workspace you plan to bill for API requests. 1. Sign in to Comfy Platform and open API Keys. 2. Click + New, enter a name, then click Generate. 3. Copy the key and save it securely. It is only shown once. 4. Go to [Settings → Billing](https://platform.comfy.org/settings/billing) and click “Add credits” to top-up (min. $5). [OPEN API KEYS](https://platform.comfy.org/profile/api-keys) [READ THE API KEY GUIDE](https://docs.comfy.org/development/api-development/getting-an-api-key) 2. 02 ### Review the migration changes Replace the base URL and use your Comfy key. Check the endpoint reference before migrating any call. **FROM** https://api.stability.ai **TO** https://stability.comfy.org **AUTHENTICATION** Authorization: Bearer The compatibility endpoint accepts Bearer authentication, not X-API-Key. Keep credentials in your environment or secret store, not in a coding-agent chat. REVIEW ENDPOINTS ## Check every endpoint you use. This is the supported route list. All routes below use POST. Check your integration against this list before switching. SDXL (3) - /v1/generation/stable-diffusion-xl-1024-v1-0/text-to-image - /v1/generation/stable-diffusion-xl-1024-v1-0/image-to-image - /v1/generation/stable-diffusion-xl-1024-v1-0/image-to-image/masking IMAGE GENERATION (3) - /v2beta/stable-image/generate/core - /v2beta/stable-image/generate/ultra - /v2beta/stable-image/generate/sd3 IMAGE EDITING (6) - /v2beta/stable-image/edit/erase - /v2beta/stable-image/edit/inpaint - /v2beta/stable-image/edit/outpaint - /v2beta/stable-image/edit/search-and-replace - /v2beta/stable-image/edit/search-and-recolor - /v2beta/stable-image/edit/remove-background IMAGE CONTROL (4) - /v2beta/stable-image/control/sketch - /v2beta/stable-image/control/structure - /v2beta/stable-image/control/style - /v2beta/stable-image/control/style-transfer UPSCALING (2) - /v2beta/stable-image/upscale/fast - /v2beta/stable-image/upscale/conservative 3D (2) - /v2beta/3d/stable-fast-3d - /v2beta/3d/stable-point-aware-3d ### CHECK THE LIMITS SD3 generation accepts sd3.5-* models. Use samples=1, except on v1 routes with Accept: application/json. Async-only routes such as Creative Upscale (/v2beta/stable-image/upscale/creative), results polling, /v1/user/*, /v1/engines/list, and other v1 engines are not supported. Audio stays with Stability AI. ### ACCOUNT SETUP DOCUMENTATION The API-key guide is available now. [READ API KEY SETUP](https://docs.comfy.org/development/api-development/getting-an-api-key) ## Q&A Image generation, editing, control, upscaling, and the listed 3D routes are available on Comfy. Use the endpoint reference above to check each call. Audio APIs stay with Stability AI; not every existing Stability route is supported. Yes. Create your Comfy API key, add credits to the same workspace, and check every route you use against the endpoint reference. Then switch the base URL and key. The transition includes a 30-day grace period after go-live; confirm the dates in Stability AI’s customer notice. For a supported call, change the base URL to [https://stability.comfy.org](https://stability.comfy.org/) and replace your Stability key with a Comfy key in the Authorization: Bearer header. Keep the same path, parameters, and response handling. Check the route and parameter limits first. There is no automatic redirect. Yes. Create a Comfy API key in the workspace you will use, then add credits to that same workspace before your first call. Your Stability key does not authenticate with Comfy. Billing for requests on Comfy runs through your Comfy workspace. Confirm the price of each endpoint before switching. This page does not promise that existing Stability credits transfer to Comfy. [Talk to the Comfy team](https://comfy.org/contact/) about your endpoints, volume, and migration plan. ## Find your path forward. Plan your image and 3D API transition with Comfy, or explore self-hosting in your own environment. Enterprise ### Running at scale? Talk to the Comfy team about volume, pricing, and support for your integration. [TALK TO COMFY](https://comfy.org/contact/) Your environment ### Prefer to self-host? If self-hosting is a better fit for your team, deploy Stability AI models in your own environment with a Self-Hosted License.
