Question
Can I get historical FanDuel prop lines?
Short answerYes, from when collection started: FanDuel API stores every line, price and status change of each prop with its timestamp, and GET /api/v1/props/{id}/history returns them oldest first. Nothing older than the start of collection is stored.
FanDuel API is an independent data service operated by FF API Inc. It is not affiliated with, endorsed by or sponsored by FanDuel.
In more detail
The history endpoint also returns the move summary: opening line, current line, line move, price move in no-vig probability, and when it last moved.
Example
curl "https://fanduelapi.com/api/v1/props/<prop_id>/history" \
-H "Authorization: Bearer $FANDUEL_API_KEY"
