OpenAI-compatible developer API

One API. Every model.

Add leading text and media models to your product with the SDK you already use. Discover live models first, then pay only for what your application consumes.

  • Works with OpenAI SDKs and familiar chat-completion calls
  • Use GET /v1/models so unsupported models never reach production
  • Prepaid usage, exact cost reporting and no automatic renewal

Questions, answered

Everything you need to start

Clear answers about models, files, API access and usage limits.

Which AI models can I use?

The picker shows only models currently supported by the site's verified provider keys, with the strongest available choices first.

Can developers inspect the API before signing up?

Yes. The public API documentation covers authentication, model discovery, chat completions, streaming and errors before you create an account.

Can it create PDFs and work with images?

You can upload files and images, request image edits, and receive finished PDF or Word downloads directly in the conversation.

How can I control usage?

Paid plans include unlimited messages on included models. High-usage models and media share one rolling 5-hour credit pool, and you can set a lower personal safety limit.

How it goes

  1. Type your question

    The box above already works. Your first message opens a chat — nothing to sign up for first.

  2. Change model whenever you like

    Ask Claude, then hand the same conversation to GPT. The thread stays; only the model changes.

  3. Keep it with an account

    Signing up saves your chats and unlocks file uploads, images and video.
