Free tools for Pinnacle odds
Answer: PinnFeed's free tools work in your browser without an account. The no-vig calculator turns the two or three prices of one market into fair odds, fair probabilities and the margin, using the same proportional method as the PinnFeed API. The pages below give the formulas and code for margin, arbitrage and Kelly sizing, so you can check every number yourself.
Want the numbers for live markets instead of typing them? Get a free key: no card, REST delayed 30 seconds, fair, fairProb and margin on every main market.

Live data in your own code#
The tools above use prices you type in. For live markets, the Free plan returns the same fields over REST with a 30-second delay. The WebSocket, which pushes each change as it happens, starts at Builder (€99/mo, 3 WebSocket connections, all 13 sports; 3-day trial, a card is required and it is charged after day 3 unless you cancel). Start with the docs.
Questions about the tools#
Do the tools cost anything?#
No. The calculator and the formula pages are free and need no account. The API has a Free plan too; paid plans are listed on pricing.
Is my data sent anywhere?#
No. The no-vig calculator computes everything in your browser. It does not send the prices you type to PinnFeed.
Will you add more tools?#
Possibly. We only list tools that exist and work today; this page is updated when one ships.
Are these betting tips?#
No. The tools do arithmetic on prices. Content is educational and for adults (18+); no outcome or profit is guaranteed.
