Looking for a tennis odds API? Here's the honest version.
We don't sell bookmaker odds — and we won't pretend to. What we sell is the data layer that makes odds make sense: results, rankings, head-to-heads, and form, back to 1968.

Most teams hunting for a tennis odds API are actually building one of two things: a product that displays prices, or a model that evaluates them. For the first, you need a licensed odds vendor. For the second, the odds are the easy half — the hard half is deep, clean historical performance data to price against. That half is this API.
The evaluation layer
Closing-line analysis, surface-adjusted expectations, fatigue features from recent-form windows, head-to-head asymmetries: all of it starts from complete results and point-in-time rankings. One key gives you 1.7M results and every ranking Monday since the 1970s to build it on.
If you need both halves
Pair a licensed odds feed with this data layer. They answer 'what's the price?' — we answer 'what should it be, given 58 seasons of evidence?'
