🔧 Input reference

Field	Type	Default	What it does
market	string (KOSPI, KOSDAQ, all)	"all"	Which Korean equity market to sweep. KOSPI = large-cap board; KOSDAQ = SME / growth board; 'all' covers both. KONEX is excluded by default (negligible short balance reporting).
ticker_filter	string	""	Restrict output to one specific 6-digit Korean ticker (e.g. '005930' = Samsung Electronics, '373220' = LG Energy Solution). Leave blank to scan the whole market. When set, the min…
min_short_position_pct	integer	1	Skip stocks whose reported short balance ratio (잔고비율) is below this percent of outstanding shares. KRX requires disclosure when net short positions reach 0.01% of float, so 0.5%+…
date_from	string	"2025-12-01"	Start date of the date range, ISO YYYY-MM-DD. Defaults to 30 calendar days before today. Only Korean trading days are queried (Mon–Fri, excluding KRX holidays — empty days are ski…
date_to	string	"2025-12-05"	End date of the date range, ISO YYYY-MM-DD. Defaults to today (UTC). The newest trading days are scraped first so a small max_records cap surfaces the most recent balances.
max_records	integer	200	Hard cap on the number of short-balance records to emit. Each record = one (stock, trading-day) pair after filters. Smoke tests run cheap at 5–20; production sweeps usually want 5…

💰 Pricing

Event	Price (USD)	When it is charged
Actor Start (apify-actor-start)	$0.005	Charged when the Actor starts running. Number of events charged depends on Actor memory (one event per GB, minimum one event).
Short record (short-record)	$0.1	Per Korea KRX short selling balance record (FSCMA Article 180-2)

Pay-per-event: you pay only for what the run delivers. A run that delivers nothing bills no result events (only the actor-start event, when the actor defines one). Example: a run that delivers 100 results costs 100 × $0.1 = $10.00 plus the start fee.
