How it works
2. Choose your plan
Choose a plan during the launch period. Pay through Stripe.
3. Start building
Get your API key, then send requests to any available model through Chat Completions or the Responses API.
Know the boundaries
What are the request limits?
Plus includes 250 requests per day. Priority includes 2,000 requests per day. Founder and Performance are truly unlimited. Fair-use and abuse-prevention controls protect the service; service-protection limits may apply. We may raise the Priority cap as demand grows. No throughput, uptime, concurrency, or model guarantee is offered.
What does the API support?
Text Chat Completions and the Responses API are supported, including native tool calling, parallel tool calls, structured output (response_format), streaming, and configurable reasoning effort. Available models are listed on this page and on the docs. All models are text-only. No image input, audio, embeddings, transcription, file storage, assistants, batch, or fine-tuning endpoints are offered.
Can I recover an API key?
No. Keys are revealed once. Rotate a lost key after reauthentication; rotation invalidates the previous key.
Can I cancel anytime?
Yes. Cancel through the Stripe customer portal. Cancellation stops renewal at the end of your current billing period.
