A Python sports-betting API: polling vs a Pinnacle WebSocket

Answer: pick the API by the job, then write Python against a documented contract. If you need many books on a poll, a multi-book REST API such as The Odds API (from $30/mo for 20,000 credits; no WebSocket at any published price, review of 9 November 2026) is built for that. If you need a sharp Pinnacle reference with live + prematch push, PinnFeed Builder (€99/mo, or €990/yr ≈ €82.50/mo) opens wss://pinnfeed.io/v1/stream and also serves REST plus timestamped no-vig closings. PinnFeed is Pinnacle-only. This is a chooser, not a latency test against any named vendor.

Two Python shapes#

Poll a snapshot (works on Free, 30 s delay, or Hobby real-time REST):

import os, requests
r = requests.get(
    "https://pinnfeed.io/v1/odds",
    params={"sport": "soccer", "main": "true", "limit": 20},
    headers={"x-api-key": os.environ["PINNFEED_KEY"]},  # ps_live_...
    timeout=10)
print(len(r.json().get("events", [])), "events")

Longer REST walkthrough: Pinnacle odds in Python (REST). A poller only sees a change on the next request, so on average it is half an interval late, plus round-trip — arithmetic, not a vendor race.

Push on Builder (Free and Hobby keys get 403 plan_lacks_ws):

# See the full example for auth, ping/pong and reconnect
# https://pinnfeed.io/answers/pinnacle-odds-websocket-python-example
# wss://pinnfeed.io/v1/stream  — subscribe, then apply snapshot and delta frames

Honest contrast (9 November 2026)#

We do not claim PinnFeed is cheaper than a $30 poller in absolute dollars, and we do not claim lower latency than any named vendor. Related: The Odds API vs PinnFeed, best sports betting data API.

Questions people ask#

Can I use The Odds API and PinnFeed together in Python?#

Yes. Poll the multi-book API for the other book's decimal, and compare it to Pinnacle fair from /v1/odds or the stream. Event matching is your job.

Does the official Pinnacle API still work for this?#

Official docs say public access has been closed since 23 July 2025, with any remaining access needing a funded account (README, opened 10 November 2026). PinnFeed is self-serve and does not need a Pinnacle account.

Which plan do I need for the WebSocket example?#

Builder or Pro. Hobby is real-time REST only.
