One base URL and key work with virtually any app, SDK or self-hosted chat client that supports a custom API address.
Route requests to OpenAI models, Claude, Stability diffusion, Azure TTS and vector database services from a single account.
Consumption is metered in points with a published multiplier, so you pay for what you use rather than a flat subscription.
Identical request bodies return cached answers for free for 24 hours, and a header can disable caching when freshness matters.

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.
