About the platform

Section titled “About the platform”

Multimodal

Image, audio and file input for supported models. Explore.

Billing

Credit-based balance. A 6% margin applies on top-up. Details.

Core concepts

Section titled “Core concepts”
  • Canonical model ID: Every model is referenced as provider/model (e.g. openai/gpt-4o, google/gemini-2.5-flash). Pass this value in the request model field.
  • API key: Each key starts with sk_. The raw value is shown only once when the key is created.
  • Account isolation: API keys, usage records, and balances stay scoped to the owning account.
  • Prompt privacy: Prompt and response content is not stored. Only limited operational metrics such as usage and cost are kept.
