How this service works
Fails to deliver of a US stock ($0.005): daily SEC data (up to 120 days), value, share of shares outstanding and the Reg SHO threshold pattern (10,000 shares and 0.5% for 5 days in a row) as a signal - THRESHOLD_LIKE, RECENT_THRESHOLD_LIKE, PERSISTENT_FAILS, OCCASIONAL_FAILS. Use before shorting or chasing a squeeze.
Output
Returns up to 120 days of daily SEC fails-to-deliver records for the requested ticker, including: raw FTD share count, dollar value of fails, FTDs as a percentage of total shares outstanding, and a classified Reg SHO signal pattern — one of THRESHOLD_LIKE, RECENT_THRESHOLD_LIKE, PERSISTENT_FAILS, or OCCASIONAL_FAILS. Returns 404 (not charged) for unknown tickers.
Example use cases
Pre-short due diligence on a stock
“Before I short BBBY, can you grab the SEC fails-to-deliver history for the last 60 days and tell me if it's showing any PERSISTENT_FAILS or threshold pattern signals?”
Identifying short squeeze candidates
“I'm hunting for short squeeze setups — pull the FTD data for AMC over the past 120 days and let me know if it's hitting the Reg SHO threshold pattern, like THRESHOLD_LIKE or RECENT_THRESHOLD_LIKE.”
Monitoring ongoing FTD pattern for a watchlist stock
“Check the latest fails-to-deliver data for TSLA — specifically whether the FTD share as a percentage of outstanding has been climbing and if there's any squeeze signal flagged in the last 30 days.”
Technical details
Endpoint
GEThttps://api.marketintelligenceapi.com/api/v1/sec/fails-to-deliver/:symbol?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need SEC-sourced, authoritative fails-to-deliver data for a specific US stock with Reg SHO threshold pattern classification built in. Prefer it over generic financial data APIs when the use case involves short-selling research, squeeze signal detection, or regulatory compliance checks — especially when you want a pre-computed pattern label (THRESHOLD_LIKE, PERSISTENT_FAILS, etc.) rather than raw FTD numbers alone.
Side effects
- 404 returned for unknown or unsupported ticker symbols (not charged)
- Ticker not in SEC FTD files (covers 17,000+ US tickers but not all symbols)
- Requested days parameter outside 5–120 range causes validation error
- Stale data if SEC has not yet published the most recent settlement cycle
- Payment failure if USDC balance is insufficient for the $0.01 per-call fee
