One AI API key for text, image, video, and code models
Call many different models through one base URL and one API key, so existing OpenAI-style clients and SDKs usually need only minor changes.
Access text and reasoning models alongside image, video, and audio/music generation endpoints from the same integration.
Route routine traffic through a value tier to reduce spend, and move critical workloads to an official tier when stability matters more than cost.
Manage credentials and usage in one place instead of juggling separate accounts, quotas, and invoices across vendors.
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.
