Overview
Moonshot AI's official international Kimi API Platform, offering OpenAI-compatible pay-as-you-go APIs for Kimi K3 / K2.7 Code / K2.6; the only free element is a one-time trial voucher for new users.
Free quota
Not permanently free: the official help center says new users registering with a mainland China mobile number get a one-time RMB 15 voucher (valid 3 months from issue, consumed before top-up balance). The international site's homepage shows no free credit; third-party sources say a minimum $1 top-up is required before calls work, plus promos like 'spend $5, get a $5 voucher'. The probed '$3.00' is K3's input price ($3 per million tokens), not a free credit.
Free models
UnknownPros
- Official first-party platform from Moonshot AI, not a relay, so no risk of misused upstream keys
- OpenAI-compatible API with formal docs and a developer console for generating API keys
- Flagship Kimi K3 supports 1M context; K2.6 / K2.7 Code are cheap ($0.95/$4 per million tokens)
- Built-in tools such as web search, code execution and file analysis
Cons
- No ongoing free quota; once the trial voucher is used up or expires it is pure pay-as-you-go
- The RMB 15 voucher targets users registering with mainland China phone numbers; overseas users likely get no free credit
- The international homepage shows no free credit; third-party sources say a minimum $1 top-up is needed to call the API
- Flagship K3 is relatively expensive ($3 input / $15 output per million tokens)
Risk flags
- No ongoing free quota: only a one-time new-user trial voucher (RMB 15, valid 3 months); listing it as a 'free API' may be misleading
- Free voucher only for users registering with mainland China phone numbers; international users may need to top up first (third parties say $1 minimum)
- The probed quotaHint '$3.00' is actually K3's input price, not a free credit, and is easy to misread
- Operated by a mainland China company; data compliance falls under Chinese law, and it is not explicitly stated whether API data is used for training
- Models are retired periodically (e.g. older kimi-k2 series), so model names may stop working
Community reputation
Moonshot AI is a leading Chinese LLM vendor, and the Kimi API is widely regarded in developer communities (Zhihu, CSDN, Reddit, etc.) as a legitimate, stable first-party commercial API, with discussion focused on pricing and K-series model capability. On the free side, most sources agree there is only a one-time new-user voucher and no permanent free tier, so listing it as a 'free API' can be misleading.
Recommendation
Suitable as a legitimate paid API for developers who need Kimi K3's long context or the low-cost K2.x coding models. If your goal is free usage, the new-user trial voucher is only good for debugging and should not be treated as a free source. Mainland China users can claim the RMB 15 voucher via platform.moonshot.cn.
