Stability AI

Stability AI on xpay — Image generation without the signup friction

Stability AI is the team behind Stable Diffusion, the open-source image generation model that democratized AI art. Developers and builders reach for Stability AI when they need to generate, edit, or upscale images programmatically—whether for product mockups, content creation, design automation, or creative workflows. Rather than managing a separate Stability AI account and billing, xpay wraps their API as an MCP tool you invoke directly from Claude Code, Cursor, or any MCP-compatible agent.

Visit Stability AI to learn more about their models and research.

What's available

• stability_ai_sdxl ($0.01/call) — Stable Diffusion XL (SDXL) for high-resolution image generation with fine-grained control over prompts, aspect ratios, and sampling parameters.

When Stability AI is the right tool

• You need to generate images programmatically from text descriptions in your agent or workflow.
• You want fine-grained control over image dimensions, guidance scale, and sampling steps.
• You're building a design or content creation tool that requires batch image generation.
• You prefer open-source model lineage and transparency over proprietary black-box APIs.
• You want to avoid managing a separate Stability AI account and billing relationship.

When to choose something else

• You need photorealistic human faces or highly specialized domains (e.g., medical imaging)—consider OpenAI's DALL-E or Anthropic's Claude vision for different trade-offs.
• You require real-time video generation or animation—Stability AI's current offerings focus on static images.
• Your use case demands extremely low latency (<1 second)—image generation inherently takes time; batch workflows may be more suitable.
• You need image editing or inpainting as your primary feature—while Stability AI supports this, dedicated image editors may be more cost-effective for that specific task.

Quickstart

To connect Stability AI's SDXL tool to Claude Code:

claude mcp add --transport http stability-ai "https://stability-ai.mcp.xpay.sh/mcp?key=YOUR_XPAY_KEY"

Replace YOUR_XPAY_KEY with your xpay API key (get one free at https://xpay.tools after email or Google signup).

Once connected, your agent can invoke the tool by name—just ask Claude to "generate an image of [description]" and it will call stability_ai_sdxl with your prompt and parameters.

Alternatively, to access Stability AI alongside all other xpay providers in one connection:

claude mcp add --transport http xpay "https://mcp.xpay.sh/mcp?key=YOUR_XPAY_KEY"

Then use xpay_discover("stability ai") or xpay_run("stability-ai/stability_ai_sdxl", {...}) to invoke tools.

Why route Stability AI through xpay?

• No Stability AI signup — xpay holds the upstream credentials; you authenticate once with your xpay API key.
• Pay-per-call, no subscription — You're billed only for the calls you make, starting at $0.01 per image. No monthly minimums or unused credits.
• MCP-native — Invoke Stability AI tools directly from Claude Code, Cursor, Windsurf, Cline, or any MCP-compatible agent without custom integrations.
• Unified billing — If you use multiple providers (Tavily, Apollo, Anthropic, etc.), one xpay bill covers them all.
• Transparent pricing — See exactly what each call costs before you run it; no surprise charges or rate-limit overages.
