How this service works
Returns bi-weekly short interest and days-to-cover for a stock.
Output
A JSON object containing the ticker, a data block with count of settlements returned, the latest settlement record (settlement date, shares short, avg daily volume, days-to-cover), and a history array of those same fields ordered most-recent-first, plus a source label and as-of timestamp.
Example use cases
Short squeeze signal detection
“Show me the last 12 short interest settlement periods for GME, including days-to-cover and average daily volume — I want to see if a short squeeze setup is building.”
Bearish positioning trend for earnings play
“What's the short interest history for NVDA over the past 6 FINRA settlements? I need shares sold short and days-to-cover to gauge bearish sentiment ahead of earnings.”
Portfolio risk monitoring for shorted holdings
“Fetch the recent short interest data for TSLA going back about 10 settlements so I can track whether short sellers are increasing or unwinding their positions.”
Technical details
Endpoint
GEThttps://agents.x402stock.xyz/api/v1/short-interest/{ticker}?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need exchange-reported FINRA short interest data with bi-weekly settlement granularity for any US-listed stock, specifically when days-to-cover or trend analysis of short positioning is required. It is the right choice over generic market data endpoints because it provides the authoritative semi-monthly FINRA figures rather than estimated or inferred short interest, and supports configurable history depth via the limit parameter.
Side effects
- Invalid or unlisted ticker symbol returns an error or empty data
- Limit parameter outside 1–100 range is rejected
- Ticker with no FINRA short interest data returns null for latest and empty history array
- Payment failure via x402/USDC blocks the request
- Rate limiting or proxy errors return 402 or 5xx responses
