Point an OpenAI or Anthropic SDK at
https://api.antarah.dev and change the model name. Everything else works as in those APIs: streaming, tool calling, structured output, images, and reasoning.
On top of that, Antara adds:
- Policies. Write a yes/no question (“Does this response reveal an API key?”). Antara checks requests or responses against it and records a decision, or blocks the request.
- Credits. Usage is billed in USD from a prepaid balance, with monthly spend limits per organization and project.
- Rate limits by tier, per key, project, and organization.
