Why KuaiAPI

Less integration hassle, focus on your product

Provider adapters, model switching, and usage management — all handled by a single gateway.

One key for all models

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.

Multi-channel routing with automatic failover

Each model runs behind multi-channel intelligent scheduling — instant failover and automatic load balancing. Session stickiness keeps long tasks uninterrupted and output style consistent.

Fully transparent pricing

Every model bills at "official price × group multiplier"; input/output are listed separately and visible on the public model plaza, with no hidden fees.

Works out of the box with major tools

Codex, Cursor, Cline, Continue, NextChat, and any client that supports a custom Base URL — two settings and you are ready.

Usage-based billing, fully auditable

Pay for what you use. Every call logs token usage and cost, with quota limits so team usage stays clear.

What we do not sell

  • No shared accounts — every customer gets their own account and their own API keys.
  • No cookies or sessions — we sell API access only, never third-party login sessions.
  • No keys of unknown origin — every channel is probed automatically and its health is published in real time.
  • No vague charges — every request comes with token counts, cost and a request ID you can audit yourself.
FAQ

Before you begin, you may want to know

Is it fully compatible with the official APIs?
Yes. Fully compatible with the standard OpenAI protocol (/v1/chat/completions, /v1/responses) and native Anthropic (/v1/messages): keep your existing SDK and simply point the Base URL at https://kuaiapi.net/v1 (OpenAI) or https://kuaiapi.net (Anthropic).
How is pricing calculated? Are there any hidden fees?
Billing uses "official price × group multiplier"; each group's multiplier is public on the model plaza, and input/output/cache are billed separately. Every charge has a detailed record — transparent rules, no hidden fees.
How do I top up?
The Recharge page supports international Visa/Mastercard cards, Apple Pay and Google Pay, processed by a licensed payment provider — we do not store card data. Note the billing unit: 1 USD = 6.8 balance units, and price lists are quoted in balance units per 1M tokens; please convert accordingly. Note: if your card is a domestic-only card without international payments enabled, your issuing bank may decline the charge — enable international payments or use another card. If it still fails, email support@kuaiapi.net.
Which tools work with it?
Codex, Cursor, Cline, Continue, NextChat, LibreChat, Cherry Studio, Dify, and any program using the OpenAI SDK. If you use Claude Code, point it at our Anthropic endpoint; Claude models carry their own group multipliers — check the price list first.
How is stability ensured?
Each model sits behind multi-channel intelligent scheduling: automatic failover, load balancing, and 24/7 live probing. Group health is published in real time on the Status page — honest and transparent.
Who do I contact if I have an issue?
Email us at support@kuaiapi.net for sales, support or feedback — we read every message and respond promptly. You can also refer to the documentation for step-by-step guides.
