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 OpenAI-compatible API key for 500+ AI models
Replace separate OpenAI, Anthropic and Google credentials with a single key and switch models by changing one line of code.
Route text, reasoning, coding, image, audio and video workloads through one OpenAI-compatible base URL without rewriting your app.
Line-item pricing per model with discounts below official vendor rates, pay-as-you-go with no monthly subscription or minimum spend.
A real-time dashboard tracks spend, latency and call volume so you can set budget alerts and compare models side by side.
