FanDuel change feed: every move since a cursor

Keep a local copy of the board current by reading only what changed since your last call.

Five kinds

new, line_move, price_move, status_change and removed, each with the previous and current state.

Cursor paging

since=0 starts at the oldest change kept; next_cursor continues exactly where the last page ended.

Cheap polling

A quiet minute returns an empty page, so a poll every few seconds costs one request each.

What it returns now

Endpoint and parameters

Code

curl "https://fanduelapi.com/api/v1/changes?since=0&limit=100" \
  -H "Authorization: Bearer $FANDUEL_API_KEY"

import os, requests

r = requests.get(
    "https://fanduelapi.com/api/v1/changes",
    params={"since": "0", "limit": "100"},
    headers={"Authorization": f"Bearer {os.environ['FANDUEL_API_KEY']}"},
)
r.raise_for_status()
body = r.json()
print(body["meta"])          # plan, delay_seconds, as_of, source_status
for row in body["data"][:5]:
    print(row)

Keys look like fd_.... Keep one in the FANDUEL_API_KEY environment variable on your server, never in browser code. Every response's meta says which plan answered, how far behind it is and how fresh the collection is.

Which plans include it

• FreeIncluded, 5 minutes behind
• DeveloperIncluded, real time
• ProductionIncluded, real time
• ScaleIncluded, real time

Read from the plans on the pricing page. Every request counts against the monthly and per-minute allowance; request quotas explains how.

Works well with

• Webhooks and streamStop polling: take each change the moment it is collected, on a connection or at your URL./api/v1/stream
• Line historyReplay a prop or a game line from the first time it was seen to now, move by move./api/v1/props/{id}/history
• Props feedRead the whole player prop board in one call, already normalised, with where each line opened./api/v1/props
