from livetennisapi import LiveTennisAPI

with LiveTennisAPI() as client:                       # reads LIVETENNISAPI_KEY
    for match in client.list_matches(status="live"):
        print(match.tournament, match.score.sets)

import { LiveTennisAPI } from 'livetennisapi';

const { data } = await new LiveTennisAPI().listMatches({ status: 'live' });

Both ship a livetennis CLI and a reconnecting WebSocket client. The MCP server gives Claude, Cursor and other LLM agents 24 read-only tools over the same data.

Every response is JSON. Authenticate with Authorization: Bearer (preferred) or an X-API-Key header — either works. A free key ($0, no card) covers everything below:

curl https://api.livetennisapi.com/api/public/v1/matches?status=live \
  -H "Authorization: Bearer $LIVETENNISAPI_KEY"

{
  "data": [
    {
      "id": 18953,
      "tournament": "ATP Wimbledon",
      "surface": "grass",
      "round": "R16",
      "status": "live",
      "players": { "p1": { "name": "…", "ranking": 3 }, "p2": { "name": "…" } },
      "score": { "sets": [1, 1], "games": [[6, 3, 2], [4, 6, 1]], "points": ["40", "30"], "server": 1 }
    }
  ],
  "meta": { "limit": 50, "offset": 0, "count": 1, "total": 1, "has_more": false }
}

¹ Bulk paging of completed matches (GET /matches?status=completed) needs the BASIC tier or any History plan; a single completed match by id (GET /matches/{id}) is FREE. ² Or any History plan — History plans work on top of a free core key. ³ Or History Pro and above.

¹ Also unlocked by any History plan, on top of a free core key.

Start free — a FREE key is fine to use from browser code (CORS is open, GET-only, no credentials mode); keep paid keys server-side.

Calling above your tier returns 403 {"error":"upgrade_required"} — never a silent empty result. Upgrade any time at livetennisapi.com/subscribe/upgrade.

• Base URL — https://api.livetennisapi.com/api/public/v1
• Timestamps — UTC ISO 8601 with a Z suffix, everywhere.
• Lists return {data, meta}; single resources return the object directly.
• Pagination — limit (default 50, max 200) and offset; page while meta.has_more is true (meta.total may be null).
• Score shape — sets is [sets_p1, sets_p2]; games is [games_p1, games_p2] where each side is a per-set list, so [[6,3,2],[4,6,1]] reads 6-4, 3-6, 2-1.
• Forward compatibility — ignore unknown fields. Additive changes land within v1, so clients should not reject responses carrying fields they don't recognise.
• Errors — 401 unauthorized · 403 upgrade_required · 404 · 429 (honour Retry-After; the body's resets_at and the X-RateLimit-Reset header give the exact UTC instant your quota resets).

• docs.livetennisapi.com — interactive API reference
• Plain-HTML reference — the same content with no JavaScript, readable by any client or crawler
• OpenAPI 3.1 specification — generate a client in any language
• llms.txt — a machine-readable summary for answer engines

Direct is cheapest, has the only free tier, and issues a key instantly. The API is also listed on the marketplaces you may already be billing through:

The API is live and serving. Anything published in this organisation is tested against the production endpoint before release — see each repository's contract tests.
