What polymarket-tennis does

Open-source Python toolkit that lines up Polymarket's tennis markets with the matches they are about. It lists open tennis markets from Polymarket's public Gamma API, pairs each one with a live match or fixture and refuses to guess when the pairing is ambiguous, then prints the market price next to the score, the server and a break-point flag, with the age of each feed. It never places orders and holds no wallet or key; it is a data layer for a bot you write yourself. The scores come from Live Tennis API, the paid service of the same team, whose free key allows 100 requests a day. MIT-licensed at github.com/livetennisapi/polymarket-tennis.

• Finds open tennis markets through Polymarket's Gamma API, filtered to match markets and moneylines
• Pairs each market with a live match by player names and date, handling reversed order, accents and shared surnames
• Returns nothing rather than a guess when two candidates are close, only one player agrees or the date is off by more than a day
• One snapshot per market: both outcome prices beside the score line, the server, a break-point flag and the age of each feed
• pmtennis command line for discover, match and watch, and the same functions as a Python library

• The code does what it says, and it says honestly what it is not. The README discloses that the toolkit is written by the team selling the score feed and calls it “vendor-authored tooling”, and the boundary is plain: no order code, no wallet, no keys, and an arena whose rules state that a paper rank says nothing about real trading, where fees, fills and latency exist. The hard part it solves is the identity problem, deciding which live match a market is about, and the matching rules are written out and covered by tests. Its own budget table is candid too: watching once a minute spends one request a poll, so the free key lasts about 100 minutes a day.
• The popularity is not what it looks like. On Nov 9, 2026 the repo showed 256 stars and 217 forks, while the organisation's 29 other repositories had between none and two stars each. Of the 294 forks GitHub listed, all but two were made between Aug 18 and Aug 31, 2026, in daily bursts of up to 72, and 77 of their owners' accounts no longer exist; those still up mostly carry generated names such as a person's name with a number and a suffix. The two issues that prompted a code change came from accounts of the same kind. The package had 40 downloads from PyPI in the month to Nov 9. We read this as a paid boost, not a user base, and the star count should be ignored.
• Read it as a well-made sample for a data product. Everything past the snapshot, deciding when to trade and placing the order, is left to you, and a live strategy would need a faster score feed than the free tier, which is where the paid plans come in. The arena's first season was the 2026 US Open; the repo and its site publish no results as of Nov 9, 2026.
