OnAPI
What is OnAPI?
OnAPI is a one-stop AI model API gateway that gives developers a single key to handle text, image, video, and code across every major frontier model—GPT, Claude, Gemini, Sora, Veo, Banana, and more. Turn models into products. Ship ideas. Two channels, you're in charge: send everyday traffic to the high-performance value tier and stretch every dollar; flip mission-critical calls to the official tier, backed by real paid keys hitting the providers directly. No reselling tricks, no smoke and mirrors, no substituting cheap models for premium ones—just a reliable safety net when it counts. Fully OpenAI-compatible. Change one line—your base_url—and you're done. Works out of the box with the OpenAI SDK, LangChain, Claude Code, Cursor, Cline, and Cherry Studio. No international credit card required, no juggling bills across half a dozen vendors. Pay with Alipay, WeChat Pay, or crypto, billed by usage, with credits that never expire.
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.
