Download the dataset

Get the full dataset as one CSV or JSONL file. If the data is older than maxAgeHours, it is refreshed automatically first. The key needs the datasets:export scope.

At its current 153,221 rows, this download costs $91.98, down to $22.995 in volume (1,533 credits) when the data is fresh enough, or $183.96, down to $45.99 in volume (3,066 credits) when it has to be refreshed first.

This is a Standard dataset: 1 credit per 100 rows cached and 2 credits live, charged on the rows in the dataset when the download becomes ready. A failed refresh is not charged. The file stays downloadable for 24 hours. See pricing.

Start a run

To get exactly the targets you want, send the parameters below as input. The call returns 202 with the run; the key needs the scrapers:run scope and the account a positive credit balance.

curl -X POST "https://api.pandorlabs.com/v1/scrapers/insider-filings-jp/runs" \  -H "Authorization: Bearer $PANDORLABS_KEY" \  -H "Content-Type: application/json" \  -d '{    "input": {      "since": "2020-01-01",      "lookbackDays": 7,      "until": "2024-12-31",      "maxFilings": 0    }  }'

A run is billed at the live rate once it finishes: 2 credits per 100 rows it collected ($1.2, down to $0.3 in volume per 1,000 rows). A run that collects nothing costs nothing.

Run, poll, read rows

The run is asynchronous. Poll it until it reaches a terminal status and its billing is paid, then page through its rows. Until then the rows endpoint answers 409 (still queued or running) or 402 (payment required).
