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 short: Live Tennis API pays 51% of every payment for the life of the subscription (early partners 60%, at our discretion).
The cookie runs 30 days, the referral code doubles as a 10%-off code, and payouts are monthly via PayPal/Wise from $20.
The placements that work
READMEs and package pages. This is for anything tennis-, sports- or betting-adjacent you maintain 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 and let it compound. (Ours is here, and 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 free API 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. 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.
