Developer content has a property no other channel has: it keeps working. A README badge, a tutorial that ranks, a package page — each keeps referring for years after you wrote it. Combined with a recurring program, that is the best risk-adjusted deal in affiliate marketing for a technical audience.
The program in one line: Live Tennis API pays 51% of every payment for the life of the subscription (early partners 60%, at our discretion), 30-day cookie, referral code doubles as a 10%-off code, monthly PayPal/Wise payouts from $20.
The placements that work
READMEs and package pages. If you maintain anything tennis-, sports- or betting-adjacent on GitHub, PyPI or npm, a one-line "powered by / works with" link with your referral code reaches exactly the people who buy API plans.
Tutorials. "How to get live tennis scores in Python" is the query your audience types; the official Python and JS SDKs make the code section short. Write the tutorial once, let it compound. (Ours is here — yours can rank too.)
MCP and agent integrations. LLM agents can call the API through the open-source MCP server — agent-tooling posts and awesome-lists are an audience nobody else is serving yet.
WebSocket demos. A live-updating scoreboard in a CodePen or a short video demos better than any static JSON. The WebSocket guide is the reference.
The mechanics
- Sign up free at affiliates.livetennisapi.com/signup; your link and code appear on the dashboard immediately.
- Use the link in prose, the code in code comments and READMEs — the code attributes without a cookie.
- Disclose the relationship (a "referral link" note is enough — and in docs, readers respect it).
- The terms are short: no spam, no brand-bidding, no misleading claims.
Why the free tier does the selling
A developer audience does not convert on a landing page — it converts in the terminal. The API's free key needs no card, the docs are public, and a first live score is a few lines of Python. Your content's job is only to get them to that first request; the product either holds them or it doesn't — and when it does, you earn 51% of every month that follows.
FAQ
How much does the Live Tennis API affiliate program pay developers? 51% of every payment, recurring for the life of each referred subscription. Referrals pay 10% less; your cut of what they pay is $13.77/mo per Pro referral and $45.90/mo per Ultra. Early partners are stamped at 60%, at the program's discretion.
Can I put a referral link in an open-source README? Yes — disclose it as a referral link. The referral code also works as a 10%-off coupon, which attributes even when the visitor arrives without your cookie.
Is there a free tier my readers can start on? Yes — a free API key with no card, public docs, and official Python/JS SDKs. Tutorial-shaped content converts precisely because readers can run the code immediately.
