Overview
duiapi (DuiAPI) is a commercial paid AI relay station built on the new-api/one-api stack, marketed as 'direct connection to official models' with pay-per-token billing; it only gives new registrants roughly $2 of trial credit and is not a free public-welfare service.
Free quota
Not a free service: primarily top-up pay-as-you-go, with only about $2 of trial credit granted to new registrants (some promo channels claim posting/joining a group to leave your ID can add more, up to ~$12 total). Once the trial credit is used up, top-up is required.
Free models
UnknownPros
- Aggregates and directly connects to mainstream large models (advertised support for Qwen3-Max, GLM series, DeepSeek series, etc.) with an OpenAI-compatible interface for easy integration
- Provides a /v1 API and a console with self-service key generation, suitable for interface testing and product prototyping
- New users get a small (~$2) credit to run real scenarios before deciding whether to top up
- Marketing emphasizes billing transparency, traceable call records, and direct official model sources
Cons
- Not a free service: core model is top-up pay-per-use with a tiny grant, so it does not fit the project's main target of 'free callable API'
- /v1/models requires authentication (401); without login the actual available models and true upstream source cannot be verified
- Operator is anonymous and the site is newly launched (short uptime), with no independent third-party reputation or long-term stability record
- Relay stations broadly carry systemic risks of stolen/shared upstream keys, model degradation, peak-time downgrading, and exit scams
- The homepage returns 403 to anonymous crawling, so public information is limited and transparency is hard to verify independently
Risk flags
- Anonymous operator, no real-name/company information, blank independent reputation
- Recently launched new site lacking long-term stability and payout history; exit-scam risk
- As a relay, it may use stolen or shared upstream official keys, possibly violating upstream terms of service
- Industry-common risks of model degradation, peak-time downgrading, and fake models
- Requests pass through the relay gateway in plaintext, creating privacy/compliance risk of prompt/business data being logged or resold
- Not free: core is top-up pay-per-use with a small grant; refunds are difficult after topping up
- /v1/models requires auth, so upstream model source and real availability cannot be verified without login
Community reputation
Apart from the promotional listing in the source directory zzsting88/relayAPI and secondhand mentions on Zhihu/self-media, no independent real-user reviews or complaints about duiapi were found on V2EX, Linux.do, NodeSeek, GitHub, or Reddit. It is described as a commercial paid relay emphasizing direct official connections, transparent billing, a 50%-off new-site promo, and a ~$2 signup credit. Overall it is a reputation-blank, anonymously operated new relay that must be viewed cautiously in light of the industry's common exit-scam, degradation, stolen-key, and data-compliance risks.
Recommendation
duiapi is a commercial paid relay station, not a free public-welfare API service, and is not a main target of this project. If you only want to try it, use the small new-user credit for limited testing; do not top up large amounts, and do not route sensitive prompts/code through it. Provided for information and risk awareness only, not an endorsement.
