{"jsonrpc":"2.0","id":1,"method":"tools/list"}ftd_security — Fails-to-deliver history for one US-listed security from the SEC's CNS fails-to-deliver file, by ticker symbol. Returns each settlement date with the number of shares that failed to deliver, the closing price, the security description and its CUSIP. A fail-to-deliver is a settlement failure — shares not delivered on time — and the SEC states it is NOT evidence of naked short selling; ordinary causes include processing delays, order-entry errors and illiquidity. Answers "what were the fails-to-deliver for GME", "has this stock had settlement failures recently".ftd_largest — The largest fails-to-deliver in one SEC reporting period, ranked by share count, from the CNS fails-to-deliver file. Returns ticker, security description, settlement date, shares failed and price. A fail-to-deliver is a settlement failure and is NOT evidence of naked short selling — the SEC says so explicitly; ordinary causes include processing delays and illiquidity. Answers "which stocks had the most failed deliveries this period".ftd_periods — Which SEC fails-to-deliver reporting periods are currently published, newest first. SEC posts one file per half month ("a" = 1st-15th, "b" = 16th to month end). Use this to pick a valid period argument, or to see how current the data is.Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
