Keep your existing client. Change the endpoint and API key, then switch models with a single field.
OpenAI, Anthropic and Responses
Use compatible chat completions, Messages and Responses endpoints with your existing tools.
One prepaid balance
Pay for token usage with no monthly fee or minimum spend. Check balance and usage in the console.
Choose a group
Groups offer different routes and multipliers. Switch groups to match your cost and reliability needs.
Every request, accounted for
We validate your key, route the request to the selected model, and record the usage-based charge. There are no hidden routing rules added to standard API behavior.
