How this service works
The exchange-reported short-interest history for a US-listed stock: total shares sold short, average daily volume, and days-to-cover for each bi-weekly FINRA settlement date, most recent first. A core short-squeeze and bearish-positioning signal. Tune how many settlements to return with `?limit=` (default 12). From x402stock, a market & economic data API (x402, USDC).
Output
Returns an ordered list of bi-weekly FINRA settlement records for the requested ticker, each containing: settlement date, total shares sold short, average daily trading volume, and days-to-cover ratio. Results are sorted most recent first, with up to 100 records (default 12) controlled by the `limit` parameter.
Example use cases
Short squeeze candidate screening
“Get me the last 12 FINRA short interest settlements for AMC so I can see how days-to-cover and shares short have been trending — I'm trying to spot a potential short squeeze setup.”
Bearish positioning research
“What does the recent short interest history look like for TSLA? Show me the last 8 bi-weekly settlements with shares sold short and days-to-cover.”
Portfolio risk monitoring
“Pull the most recent short interest data for RIVN — I want to know how heavily shorted it is right now and whether the short interest has been increasing or decreasing over the past few months.”
Technical details
Endpoint
GEThttps://agents.x402stock.xyz/api/v1/short-interest/:tickerWhen to prefer
Choose this endpoint when you need structured, historical short interest time-series data (shares short, daily volume, days-to-cover) for a US-listed stock across multiple bi-weekly FINRA reporting periods. It is ideal for short squeeze analysis, bearish sentiment trend monitoring, and quantitative screening. Prefer it over real-time price feeds when the goal is understanding short positioning dynamics rather than current price. Payment via USDC x402 makes it suitable for autonomous agent workflows without pre-registration.
Side effects
- Invalid or unknown ticker symbol returns an error or empty result
- Requesting a non-US-listed or OTC security may return no data
- limit parameter out of range (≤0 or >100) returns a validation error
- Ticker for a recently delisted stock may have incomplete or no history
- FINRA data lag means most recent settlement may be up to 2 weeks old
