Overview
spark-api-open.xf-yun.com is the OpenAI-compatible HTTP endpoint (/v1/chat/completions) for iFlytek's Spark LLM; you must create an app and obtain an APIPassword in the iFlytek Open Platform console (xfyun.cn) before calling it, and Spark Lite is free long-term.
Free quota
Spark Lite (model=lite) has been officially 'permanently free' since May 2024 with unlimited tokens but QPS caps; new users can also claim one-off free token packs for other tiers (commonly around 2M tokens, subject to current console promotions). Free access requires real-name registration and app creation on xfyun.cn.
Free models
Spark Lite (model=lite)Spark Pro/Max/4.0 Ultra (one-off free token packs only; paid after depletion)Pros
- First-party vendor endpoint (iFlytek, a listed Chinese company)—not a third-party relay, no stolen-upstream-key risk
- Spark Lite is officially declared permanently free with unlimited tokens, suitable for sustained low-cost use
- OpenAI-compatible HTTP endpoint (spark-api-open.xf-yun.com/v1/chat/completions) alongside the legacy WebSocket API
- Low latency from mainland China (164ms probed), complete Chinese docs, clear legal entity
Cons
- This host is only an API endpoint and returns 401 on probe; you must register, complete real-name verification, and create an app on xfyun.cn to get an APIPassword
- Spark Lite is a lightweight, weaker model; stronger tiers (Pro/Max/4.0 Ultra) become paid once the gifted tokens run out
- The free tier is QPS-limited (typically ~2 concurrent streams), unsuitable for high-concurrency production
- Requires a mainland-China phone number/real-name KYC; anonymous or overseas use is constrained, and content is subject to domestic compliance monitoring
Risk flags
- This host is a bare API endpoint returning 401 unauthenticated; registration happens on the xfyun.cn console
- Only the Lite model is free; gifted tokens for Pro/Max/4.0 Ultra convert to pay-as-you-go once exhausted—watch console balance
- Real-name verification is required in mainland China; privacy and content compliance follow domestic regulation, so avoid sensitive data
- The free policy is set unilaterally by the vendor; 'permanently free' terms have historically been revised across vendors
Community reputation
The iFlytek Open Platform is a mainstream first-party Chinese LLM platform; many community tutorials (CSDN, Zhihu, cnblogs) treat Spark Lite as the go-to entry-level 'free LLM API' and confirm it is permanently free for lightweight tasks such as summarization and RAG. Negative feedback centers on Lite's limited capability, low QPS, and KYC requirements—not on exit-scam or key-theft risks.
Recommendation
As a first-party Chinese vendor free tier, it suits lightweight Chinese-language workloads (summarization, classification, RAG Q&A) and personal projects; create an app on xfyun.cn to obtain the APIPassword, mind the Lite-vs-paid quota split, QPS caps, and KYC/compliance requirements, and don't treat gifted tokens as a long-term guarantee.
