One key workflow, many clients

Claude Code, Codex CLI, Gemini CLI and OpenAI-compatible SDKs can all connect through QuotaAPI.

Usage records built in

The console gives you balance, billing, request logs and error details for ongoing operations.

Compatible protocol surfaces

Use OpenAI Chat Completions, Responses, Embeddings, image generation, Anthropic Messages and Gemini v1beta from the same service.

quotarouter.ai can be your unified Base URL
