Frequently asked questions (FAQ)
Account and Sign-In
Q: I registered but never got the verification email. A: Check your spam folder; make sure the email address is correct; if it still doesn't arrive, contact support (support@kuaiapi.net) for manual activation.
Q: What if I forgot my password? A: On the sign-in page, click "Forgot Password" and reset it via email; if that option isn't enabled on the site, contact support (support@kuaiapi.net).
Q: Can I change my sign-in email? A: Yes, in your profile. After the change, sign in with the new email.
Quota and Charges
Q: Why does it ask me to top up when my balance is 0? A: The platform bills by usage. With a balance of 0 you can't make API calls; top up or redeem to continue.
Q: Can I use a subscription and my balance at the same time? A: Yes. The subscription covers the group's quota, while the balance is charged by usage. They don't conflict; just make sure the group matches.
Q: Can a redemption code be refunded? A: Virtual goods are generally non-refundable. See the site policy for details.
API Errors
Q: What does a 401 mean? A: The key is invalid, disabled, or written incorrectly. See 401/403.
Q: Is a 429 rate limiting? A: Not necessarily. Insufficient balance or exhausted quota can also return 429. See 429 troubleshooting.
Q: Getting a 404 for the model? A: Go by the model names listed in the group; don't copy them from other platforms.
Clients
Q: Can Claude Code connect to this site? A: Yes. The key must be bound to an Anthropic platform group. See Claude Code for setup.
Q: How do I connect Codex? A: Bind the key to an OpenAI group and set the Base URL to https://kuaiapi.net/v1. See Codex.
Q: Can one key be used for both Claude and GPT? A: No. Each key is bound to a single group (one platform). If you need multiple platforms, create multiple keys.
Security
Q: What should I do if my key leaks? A: Disable or delete it and create a new one immediately; check your usage records for anything unusual.
Q: I lost my Two-Factor Authentication device. A: Sign in with a recovery code. If you didn't save one, contact support (support@kuaiapi.net) to reset it.
Other
Q: Can I use the API for automation? A: Yes. Keep concurrency and request rates under control, and follow the usage policy.
Q: Who do I contact if I have a problem? A: Support support@kuaiapi.net; when you submit feedback, attach the request ID / order number / screenshots.
