How to use OnAPI?

Three steps to get up and running. OpenAI-compatible—no code rewrite needed: 1. Sign up and create an API key — Email signup, no international card required. Generate a key in the console with one click. New users get $0.20 in free credit. 2. Top up your balance — Pay with Alipay, WeChat Pay, or crypto. Pay-as-you-go, no minimum, use anytime, credits never expire. 3. Swap one line of code — Point base_url to https://api.onapi.ai/v1, drop in your OnAPI key, and you're live—fully compatible with the official OpenAI SDK. 4. Call any model — Supports Chat Completions, Anthropic Messages, streaming, function calling, long context, and every other native capability. Switch models by changing the model parameter—same request format, one key for GPT, Claude, Gemini, Sora, Veo, Banana, and the rest. 5. Track usage — Monitor request volume, token consumption, spend, and error rates per key and per model in the OnAPI console, in real time.
