Algorithmic sports betting with a Pinnacle odds API

Updated 10 November 2026 · PinnFeed · 2 min read

Answer: an algo stack that uses Pinnacle as the sharp reference usually has four data jobs: ingest live prices, keep a local book, attach timestamped no-vig closings as labels or features, and keep every feature strictly earlier than the close. PinnFeed fills the first and third: wss://pinnfeed.io/v1/stream on Builder for live + prematch deltas, and GET /v1/closing?date=YYYY-MM-DD for the UTC-day close with fair / fairProb. It does not place bets, and it is not a multi-book feature store. This page is educational (18+). We do not promise an edge, and we do not claim a deeper closing history than other Pinnacle feeds.

Where Pinnacle sits in the stack#

Ingest — subscribe on /v1/stream (Builder) or poll /v1/odds. Store event.id, market, decimal, fair, fairProb, margin, maxStake and a timestamp.
State — apply snapshot then delta frames; drop on remove. Protocol: snapshot vs delta.
Labels / features — join GET /v1/closing only at instants your model would already have had. Training on the result, or on a close your bot would not have seen, is look-ahead. Narrower recipe: ML on Pinnacle closing odds, backtesting / CLV.
Risk and execution — a maxStake floor around 100 is a common thin-line filter. Execution, if any, is on a licensed book and is out of band. PinnFeed is odds data only.

import os, requests
r = requests.get(
    "https://pinnfeed.io/v1/closing",
    params={"date": "2026-11-03", "sport": "soccer", "main": "true", "limit": 100},
    headers={"x-api-key": os.environ["PINNFEED_KEY"]}, timeout=10)
# Each row is that UTC day's Pinnacle close — use fairProb as a label
# and keep only features timestamped strictly before the close.

The closing archive is a UTC-day snapshot, not tick-level history, and it grows from the day it started — see REST docs for the earliest date. Related: bot architecture, Python sports-betting API chooser.

Closing endpoints need Builder (€99/mo, or €990/yr ≈ €82.50/mo) or Pro. Hobby (€29/mo) is real-time REST only, with no stream and no closing archive.

Try it#

Start a 3-day Builder trial (€99/mo, VAT incl. where applicable) or get a free delayed REST key to inspect the live schema. Paid plans: 3-day trial; a card is required and it is charged after day 3 unless you cancel. Pricing.

Questions people ask#

Will this make a profitable model?#

No promise. The page is a data architecture. Edges vanish, limits move, and look-ahead will fool a backtest.

Is this the same as the ML closing-odds page?#

That page is the labelling pattern. This one is the wider algo stack — ingest, state, closings, risk — still without an execution cookbook.

Which plan includes closings and the WebSocket?#

Builder or Pro.
