The Stability AI REST API provides endpoints for image generation, editing, upscaling, 3D model generation, and account management. The API supports both v1 (engine-based) and v2beta (stable-image) endpoint patterns. The API exposes 27 endpoints secured with bearer authentication.
Install Jentic One Beta
Connect the Stability AI API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Stability AI API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.
Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine
# On the machine that will host your Jentic One instance:
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fstability.ai%2Fstability" | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fstability.ai%2Fstability" | sh
jentic register # connects your agent to your Jentic One instanceJentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.
Capabilities
What an agent can do with Stability AI API.
Generate image using Stable Image Ultra
Upscale image using Fast Upscaler
Start Creative Upscale
Fetch Creative Upscale result
Monitor Stability AI API operational status and events
Use Cases
Patterns agents use Stability AI API for, with concrete tasks.
★ CRM Operations
Use the Stability AI API to perform crm operations programmatically. The API provides 27 endpoints covering core functionality including generate image using stable image ultra, generate image using stable image core, generate image using stable diffusion 3.
Call POST /v2beta/stable-image/generate/ultra to generate image using stable image ultra
Automated Generate Management
Automate generate operations by combining multiple Stability AI API endpoints. Agents can generate image using stable image core and then generate image using stable diffusion 3 in a single workflow.
Call POST /v2beta/stable-image/generate/core to generate image using stable image core, then verify the result
AI Agent Integration via Jentic
AI agents discover and call Stability AI API endpoints through Jentic without managing credentials directly. An agent searches for the required operation by intent, receives the matching endpoint schema, and executes the call with Jentic-managed authentication. This eliminates the need to read API documentation or handle bearer tokens manually.
Search Jentic for 'generate image using stable image ultra', load the operation schema, and execute with Jentic-managed credentials
Key Endpoints
27 endpoints — the stability ai rest api provides endpoints for image generation, editing, upscaling, 3d model generation, and account management.

Why Jentic?
What agents get from Jentic-routed access to this vendor.
Setup
Wiring the Stability AI API by hand means learning its bearer auth against api.stability.ai and polling async results for creative upscales yourself. Through Jentic you install once, import the Stability AI API from the API Directory, store the bearer token once, and your agent calls it.
Permission scoping
You can limit the agent to the operations it needs, such as generating a core image or running a fast upscale, so it produces the image types you allow and never runs inpaint edits or creative upscales unless you add those operations.
Credential isolation
Your Stability AI bearer token is stored once, encrypted, by your own Jentic One instance and injected at execution time. It never enters the agent's prompt, logs, or context.
Intent-based discovery
Agents search Jentic by intent such as 'generate an image with Stable Image Core' or 'upscale this image', and Jentic returns the matching Stability AI operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs
Specific to using Stability AI API through Jentic.
What authentication does the Stability AI API use?
The Stability AI API uses a Bearer token in the Authorization header. Through Jentic, these credentials are stored encrypted in your Jentic One instance and injected at execution time, so raw secrets never enter the agent context.
Can I generate image using stable image ultra with the Stability AI API?
Yes. Use the POST /v2beta/stable-image/generate/ultra endpoint. The API returns structured JSON responses that agents can parse and act on directly.
What are the rate limits for the Stability AI API?
Rate limits are not specified in the OpenAPI spec. Check the vendor documentation for current limits. Through Jentic, rate limiting is handled automatically with retry logic built into the execution layer.
How do I generate image using stable image ultra through Jentic?
Install the Jentic SDK with pip install jentic, authenticate through Jentic One, the self-hosted execution layer, then search for 'generate image using stable image ultra'. Jentic returns the matching Stability AI API operation with its input schema. Load the schema and execute the call - credentials are injected automatically.
How many endpoints does the Stability AI API have?
The Stability AI API exposes 27 endpoints covering generate, upscale, edit operations.
Can I limit what my agent is allowed to do with the Stability AI API?
Yes. Because you self-host Jentic One, your own rules decide which Stability AI operations and credentials the agent may use. You can scope the agent to just the calls it needs, such as generating a Stable Image Core image or running a fast upscale, so it produces only the image types you allow. It never runs inpaint edits or creative upscales unless you explicitly add those operations.
