PARAMETERS

get_bulk_block_deals parameters
Name	Type	Required	Default	Description
`query`	`string`	Yes	—	Company name, NSE symbol, BSE code or ISIN.
`deal_type`	`string`	No	—	"bulk" or "block"; omitted returns both.
`days`	`integer`	No	90	Trailing lookback window, clamped 1–1825.
`limit`	`integer`	No	100	Max rows, newest first, clamped 1–500.

RESPONSE DATA

deals — trade_date, client_name, buy_sell ("BUY"/"SELL"), quantity, price, remarks (bulk only).
One row per counter-party + direction, not a matched buyer/seller pair — NSE doesn't publish that pairing.

NOTES

Only NSE's most-recently-published trading day is fetched upstream (no reachable historical bulk/block archive) — coverage starts from whenever the nightly refresh job began running, not further back.

Also available via REST: /stocks/{q}/bulk-block-deals
