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 open-source AI gateway for 100+ LLM providers
Call 100+ providers and 1,800+ models using one request format, so you can swap models without changing application code.
Issue scoped keys per team, project or app, set monthly spend caps and see exactly who is driving usage and cost.
Distribute traffic across deployments, retry on failure and automatically fall back to another model or provider when one goes down.
Dashboards for request volume, tokens and cost per model, with support for logging and analytics integrations.
