UNIFIED BILLING

One API key. One balance. One invoice. Add credits once and use them across every provider. Per-token pricing with no platform markup on major models.

03

ZERO INFRASTRUCTURE

Serverless by default. No GPUs to provision, no containers to manage, no scaling to configure. Send a request, get a response. We handle everything in between.

OPENAI-COMPATIBLE

Everything you use in the OpenAI SDK works out of the box.

  • Chat Completions
  • Streaming
  • Function Calling
  • Vision / Multimodal
  • Embeddings
  • JSON Mode
  • File Uploads
  • Tool Use
