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.
One API key for hundreds of AI models from every major provider
Six hundred plus models for text, image, video, audio, transcription, embeddings, and reranking behind one OpenAI-compatible API.
Requests are rerouted to another provider on outages or rate limits by default, so you don't write custom retry logic.
The auto-router selects a model and provider per request using live marketplace performance and pricing data.
Track spend, tokens, and usage per model, provider, and team member in one place, including bring-your-own-key usage.
