KuaiAPI is an AI API gateway for developers. It supports GPT, Claude, DeepSeek, Grok, and more, and works with Codex, Cursor, Cline and any OpenAI-compatible SDK. Keep your familiar SDK — just point the Base URL at us.
from openai import OpenAI client = OpenAI( api_key="YOUR_API_KEY", base_url="https://kuaiapi.net/v1" # only change this line ) resp = client.chat.completions.create( model="gpt-5.6-sol", messages=[{"role": "user", "content": "Hello"}] )
Designed for heavy coding use with low first-token latency. Sign up for a $0.30 trial (≈500K tokens) to test full-strength GPT before you commit.
Provider adapters, model switching, and usage management — all handled by a single gateway.
No need to register, top up, and maintain balances across multiple platforms. One API key reaches every connected model; it is natively OpenAI-SDK compatible, so your existing code works as-is.
Each model runs behind multi-channel intelligent scheduling — instant failover and automatic load balancing. Session stickiness keeps long tasks uninterrupted and output style consistent.
Every model bills at "official price × group multiplier"; input/output are listed separately and visible on the public model plaza, with no hidden fees.
Codex, Cursor, Cline, Continue, NextChat, and any client that supports a custom Base URL — two settings and you are ready.
Pay for what you use. Every call logs token usage and cost, with quota limits so team usage stays clear.
From sign-up to your first request in just a few minutes.
Register on KuaiAPI and sign in to the console. New users automatically receive a $0.30 trial (≈500K tokens).
On the "API Keys" page, create a key, choose the model group to bind, and save it.
Keep your existing SDK and call logic; simply point the address at us and start.
All available models, their groups, and live prices — public and viewable without sign-up.
Sign up, generate a key, and complete your first multi-model call in minutes.
