How this service works
Settlement fails-to-deliver for a US-listed stock from the SEC's semi-monthly data: the aggregate shares that failed to deliver on each settlement date, with the reference price, most recent first. A niche short-pressure and squeeze signal. ?limit= records (default 30). Sourced from SEC EDGAR. From x402stock, a pay-per-call market & economic data API. Pay per request in USDC via x402, no API key.
Output
A list of semi-monthly settlement records for the requested ticker, each containing the settlement date, the aggregate number of shares that failed to deliver, and the reference price on that date. Records are returned most recent first, up to the requested limit (default 30, max 120), spanning up to the requested number of semi-monthly periods.
Example use cases
Meme stock squeeze signal check
“Show me the most recent 60 fails-to-deliver records for GME from SEC data — I'm trying to see if FTD counts are climbing as a possible squeeze indicator.”
Short pressure research on a biotech
“Get me the SEC fails-to-deliver history for NVAX for the last 4 semi-monthly periods so I can see if there's unusual settlement failure activity.”
Automated FTD monitoring for a watchlist
“Fetch the latest 30 fails-to-deliver entries for BBBY from SEC EDGAR — I need the share count and reference price on each settlement date to track short pressure trends.”
Technical details
Endpoint
GEThttps://agents.x402stock.xyz/api/v1/fails-to-deliver/:ticker?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need official SEC EDGAR fails-to-deliver data for a specific US-listed stock as a niche short-pressure or potential squeeze signal. It is the right choice when you want authoritative regulatory settlement failure counts rather than derived short-interest estimates or borrow-rate proxies. Prefer this over generic financial data APIs when the specific SEC semi-monthly FTD series is required.
Side effects
- Unknown or invalid ticker returns empty results or 404
- Limit parameter out of range (must be 1–120) returns validation error
- Periods parameter out of range (must be 1–6) returns validation error
- SEC EDGAR source data lag may mean the most recent semi-monthly period is not yet available
- Payment failure via x402 (insufficient USDC balance or unsupported wallet) blocks the request
