One OpenAI-compatible key for discounted GPT, Claude and Gemini access
The catalogue spans over 90 models across LLMs, image, video, audio and embedding endpoints, individually priced per million tokens.
Each listed provider passes an LLM fingerprint test intended to confirm you receive the exact model you paid for, with no silent substitution.
If a routed channel goes down, requests are automatically routed to the next verified provider, so production calls keep running without manual key rotation.
Use one key and one prepaid balance across every model, with an OpenAI-compatible base URL for tools like Cursor, LangChain and LiteLLM.
Zhipu AI's open platform for GLM large models, multimodal APIs, and agent building
Unified access to GLM large language models plus vision, OCR, speech, image, and video endpoints through one account.
Build tool-using agents and expose or consume MCP services to connect models to external systems.
Create managed knowledge bases and retrieval pipelines so models can answer with your own documents.
Tune models on your data and prototype prompts interactively in the browser before shipping.
