The first $100 is the milestone that matters in any recurring-commission program, because it is not a one-off — the same referrals that got you there keep paying every month. This is the shortest honest route to it.
The terms, up front
- 51% of every payment, every month, for the life of the subscription. Refer a developer once; earn on them for as long as they stay subscribed.
- Your audience gets 10% off — the link gives, it doesn't just take.
- 30-day attribution cookie.
- Monthly payouts via Stripe (automatic, with 1099s), PayPal or Wise.
- Free to join, at affiliates.livetennisapi.com.
Right now there is also an early-adopter window: the first affiliates lock in a boosted 60% rate, on a limited number of spots, and the window closes September 17, 2026. Details on the program page.
The math: two referrals is the whole game
Plans run $9.99 (Basic), $29.99 (Pro) and $99.99 (Ultra) per month. Developers building something real most often land on Pro at $29.99, so use that as the working case:
| Referrals | At 51% | At the 60% launch rate |
|---|---|---|
| 1 Pro | $15.29/mo | $17.99/mo |
| 2 Pro | $30.59/mo | $35.99/mo |
| 1 Ultra | $50.99/mo | $59.99/mo |
Two Pro referrals pay $30.59 every month — cumulative $100 arrives inside four months, and inside three at the launch rate. One Ultra referral gets you most of the way on its own. That is the entire model: not a hundred clicks, two developers who genuinely need live tennis data.
To be clear about what this is: arithmetic on list prices, not a promise. What you earn depends on who you reach — which is the next section.
The three audiences that convert
Betfair-trading audiences. People who trade tennis markets need live scores and market prices their tools can react to. The API serves both over REST and WebSocket — a concrete upgrade over refreshing a scoreboard.
Tennis-stats readers. If you write a newsletter or blog about tennis numbers, your readers include the people who want the data behind the analysis. "Here is the API I pull this from" is the most natural affiliate sentence ever written.
Betting-bot developers. Anyone building a model or a bot needs a feed their code can consume: official Python and JavaScript SDKs, a WebSocket stream, and an MCP server for AI agents. Developers convert on docs, so link the docs.
Start with the audience you already have
The first sale almost never comes from a new website. It comes from surfaces you already own:
- the README of a tennis or betting repo you maintain
- your newsletter, where a one-paragraph honest mention fits naturally
- a Discord or Telegram community where you already answer questions
- YouTube descriptions under videos your audience already watches
- an old blog post that still ranks — add the section it was missing
One honest paragraph in front of people who already trust you outperforms a site built from zero every time.
Promote it honestly
- Disclose the relationship, every time. "This is an affiliate link" costs you nothing with an audience that trusts you — hiding it costs everything.
- Claim only what the docs show, and link them. If you're unsure whether the API does something, check before you write it.
- No earnings promises to your audience, and none from us to you — the table above is arithmetic, your results depend on your reach.
- Post where you already contribute. A helpful answer with a relevant link is promotion; the same link pasted cold is spam, and it converts like it.
Honest promotion is not just the condition of staying in the program — it is what actually converts developers, who check claims by profession.
The kit does the production work
The portal's Assets page ships everything pre-built: banners and social cards in standard sizes with copy-paste embed codes, a swipe-copy library, email templates, DM openers and an API value cheat sheet — each with your referral link already filled in. Producing the creative is not the work; choosing where to place it is.
The two-week mindset
- Day 1 — sign up, grab your link and the kit.
- Days 1–3 — place the link on every surface you already own (README, newsletter footer, video descriptions, community profile).
- Week 1 — publish one honest piece: a review, a tutorial, or "how I use it" with real code.
- Week 2 — one follow-up, plus one genuinely helpful community answer where the link belongs.
Starting from an existing audience, a first sale inside two weeks is a realistic target. After that the model works for you: the same two referrals that make the first $100 keep paying at 51% — for life.
