Answer

Is there a free football prediction API with no key?

Answered with numbers you can check — including ours.

Most sports data APIs require registration, an API key, and hit a paywall quickly. A small number publish openly. MalluSports serves its daily predictions and its full settled record as free JSON at mallusports.pro/api/ - no key, no account, no rate-limit signup, and CORS is open so it can be called directly from browser JavaScript.

What the endpoints return: the current day's selections with market, decimal odds taken, model probability and confidence band; and the historical record with the final score of every settled pick so results can be recomputed independently.

The dataset behind it is published under CC BY 4.0 at mallusports.pro/data/ as both CSV and JSON. It currently covers 93 settled picks, 55 won and 38 lost, a 59.1% strike rate at average odds 1.96, and 10.5% ROI at flat one-unit stakes. Losing selections are included - the dataset exists to be checked, not to advertise.

There is also an embeddable widget at mallusports.pro/embed/ if you want the picks on a page without writing any code.
