Questions & Answers

As answered by people managing Diffyn and Live Tennis API.

What makes your product unique?

Diffyn's answer

Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.

Live Tennis API's answer:

Most sports-data APIs hand you a score every few seconds. Live Tennis API hands you the match point by point — server, game and set state, tiebreaks — with a model win-probability on every point, over one REST + WebSocket feed.

It covers the whole professional tour: ATP, WTA, Challenger and ITF, singles and doubles, not only the main-tour matches. And the same key opens the historical layer: point-by-point tapes back to 2023, match-winner market odds, as-of-match rankings for backtests, and shot-by-shot charting for 11,000+ matches going back to 1960.

Why should a person choose your product over its competitors?

Diffyn's answer

Diffyn is the platform that specializes on both change management and multi-model analysis.

Live Tennis API's answer:

  • Depth: point-level live data, in-play statistics and win-probability, not just scores.
  • Coverage: ATP, WTA, Challenger and ITF — including the lower tiers many feeds skip.
  • Price: a free tier with no card, paid plans from $9.99/month, and Ultra at $99.99/month with 500k requests/day and the WebSocket feed.
  • Developer experience: OpenAPI 3.1 spec, official Python and JavaScript SDKs, an MCP server for AI agents, instant keys, and upgrades prorated in place on the same key.
  • Honesty about coverage: a /history/coverage endpoint states the measured completeness per tour and season instead of promising 100%.

Which are the primary technologies used for building your product?

Diffyn's answer

React, Next.js, POSTGRESQL

Live Tennis API's answer:

  • Python (Flask, SQLAlchemy, scikit-learn) for the API and the win-probability model
  • PostgreSQL for match, point and odds storage
  • Redis and Centrifugo for the real-time WebSocket push feed
  • Cloudflare in front of the API; Stripe for billing
  • OpenAPI 3.1 spec, with official Python and JavaScript SDKs and an MCP server

How would you describe the primary audience of your product?

Diffyn's answer

Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.

Live Tennis API's answer:

Developers and small teams building tennis products: live-score apps and dashboards, betting and trading models, fantasy and prediction tools, and AI agents that need structured tennis data.

A second group is researchers and quants who want point-by-point history, as-of-match rankings and shot-level charting for backtests.

The pricing is aimed at individual developers and startups rather than broadcasters.

What's the story behind your product?

Diffyn's answer

I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.

Live Tennis API's answer:

Live Tennis API started in 2026 as the data layer behind the founder's own tennis trading research: a point-by-point live feed with a win-probability model for every professional match, including Challenger and ITF.

Rather than keep it internal, the feed, the model and the historical tape were opened as a public API in July 2026, with a free tier so developers can try it without a card. It is operated by JSB Holdings LLC, a small Delaware company.
