China A-Stock Data API Platform

A subscription-based API service providing real-time and historical data for Chinese A-Share stocks across multiple data sources. Target Chinese traders, financial analysts, and algorithmic trading firms who need reliable, aggregated market data.

Retail algorithmic trading in China has grown significantly alongside platforms like Futu and Tiger Brokers normalizing self-directed quant strategies, and the fragmented state of A-share data — split across Wind, Tushare, JoinQuant, and broker APIs — creates genuine aggregation value. Wind Financial Terminal is the dominant incumbent for institutional users but is priced out of reach for indie quant developers and small firms, leaving a real gap in the $50–500/month tier. The $5k–20k/mo revenue band is plausible but requires volume; at $99/month per subscriber that's 50–200 paying customers, which is achievable but demands strong distribution into Chinese developer communities like SegmentFault or WeChat groups since English-language channels won't reach this audience. The single most likely failure mode is data licensing: sourcing legitimate, redistributable real-time A-share data is legally complex under CSRC rules and exchange agreements, and getting cut off from upstream data sources — or hit with a cease-and-desist — can kill the product overnight.
