What you get
- One API key, every model. Chat, completions, vision, and embeddings all authenticate with the same
sk-…bearer token. - Account-level credit, per-key rate limits. Your balance is shared across every key on the account; each key has its own requests-per-minute limit. Exceed either and you get an unambiguous 402 or 429 with headers explaining why.
- Dollar-denominated credits. Add a credit card, then spend down at per-model rates. No token packs, no subscriptions.
- $10 of free credit on signup so you can start evaluating right away.
OpenAI compatibility
The surface is intentionally identical to OpenAI’s for the endpoints we support. If your code runs againstapi.openai.com, swap the base_url and the model id — that’s the whole migration. See the compatibility matrix for what’s in and out at launch.
