Use Cases for one-api

Unified LLM Gateway

Put OpenAI, Anthropic Claude, Gemini, DeepSeek, ChatGLM and other providers behind one OpenAI-compatible base URL so existing clients only need their endpoint changed.

Load Balancing Across Providers

Register several upstream channels and let requests spread across them automatically, or pin a specific one by appending its channel ID to the token.

Metered Team Access

Issue tokens carrying an expiry date, a spending quota, allowed IP ranges and per-model restrictions, then review consumption in the quota detail log.

Reseller Billing

Generate redemption codes in batches so users can top up their own balance, with per-group rate multipliers charging different prices to different tiers.
