AI/ML API is a unified gateway that gives developers one API key and one OpenAI-compatible endpoint for 1000+ AI models covering chat, image, video, audio, and embeddings.
About
AI/ML API is a unified inference gateway that lets developers call more than 1000 AI models from many providers — including OpenAI, Anthropic, Google, DeepSeek, ByteDance, Mistral, Cohere, and Alibaba Cloud — through a single API key and a single bill. Instead of signing up with each vendor separately and maintaining different integrations, teams point their existing OpenAI-style requests at the service and switch models by changing one string in the request.
The platform covers a wide range of modalities: chat and reasoning models, code generation, image generation, video generation, voice and speech-to-text, music, embeddings, 3D generation, OCR, and safety and moderation. Developers authenticate with a bearer token, use standard endpoints such as /v1/chat/completions and /v1/images/generations, and manage keys through a web dashboard. A browser-based playground lets users test models before writing code, and an MCP endpoint connects the same model catalog to agents and tools like Claude, Claude Code, and Cursor.
Key Features
Pricing & Fees
- Pricing: Usage-based, per 1M tokens, with volume discounts. Examples from the pricing page include Claude Sonnet 5 at $2.60 input / $13 output, DeepSeek V4 Flash at $0.39 / $1.56, and Chat GPT 3.5 Turbo at $0.65 / $1.95. Current rates are at aimlapi.com/ai-ml-api-pricing.
- Free tier: A free playground tier is available for trying models without committing to paid usage.
- Single billing: One key and one bill cover every provider in the catalog, simplifying vendor management.
- Agent compatibility: The service states compatibility with popular agents, and the MCP endpoint documents setup steps for Claude Desktop, claude.ai, Claude Code, and Cursor.
Who It's For
AI/ML API is aimed primarily at developers and engineering teams building AI-powered applications — chatbots, content generation pipelines, agent frameworks, transcription and voice features, or image and video tooling — who want to compare or switch models without managing many provider accounts. Indie builders and startups benefit from the single key and free playground when prototyping, while larger teams can use volume discounts and the enterprise options mentioned on the site. It is a developer API rather than an end-user app, so some programming knowledge is expected.
FAQ
What is AI/ML API?It is a unified gateway that provides access to 1000+ AI models from providers such as OpenAI, Anthropic, Google, DeepSeek, and ByteDance through one API key and one bill, using an OpenAI-compatible request format.
Is there a free tier?Yes, the platform offers a free playground tier for testing models, and a "Try For Free" sign-up option; paid usage is billed per token.
How much does it cost?Pricing is usage-based per 1M tokens and varies by model — for example, $0.39 input for DeepSeek V4 Flash versus $6.50 input for Claude Opus 5 — with volume discounts listed on the official pricing page.
Does it work with agents and tools like Claude or Cursor?Yes, AI/ML API offers an MCP endpoint at mcp.aimlapi.com with documented setup instructions for Claude, Claude Code, Cursor, and other MCP clients.
How is authentication handled?REST requests use an `Authorization: Bearer` header with a key from aimlapi.com/app/keys, while the MCP endpoint supports OAuth 2.1 with PKCE and dynamic client registration or a bearer-token header.
