livetennisapi #

A Dart and Flutter client for the Live Tennis API — real-time tennis scores, players, rankings, match history, head-to-heads, match-winner market prices and model win-probability for ATP, WTA, Challenger, ITF and juniors, over REST.

• Pure Dart, Flutter-friendly. Depends only on package:http; no Flutter dependency, so it runs in a server, a Flutter app, or on the web.
• Typed and null-correct. Immutable models with fromJson, a nullable Score, string points, and player-major games handled for you.
• Forward-compatible. The API ships additive changes within v1; unknown fields never break decoding and stay reachable via each model's raw map.
• Typed errors. UpgradeRequiredException (403) names the tier you need; RateLimitedException (429) carries retryAfter — and resetsAt when the daily quota is spent.

Install #

dependencies:
  livetennisapi: ^1.0.0

The latest version published on pub.dev is 1.0.0; newer versions (1.2.x) are tagged on GitHub and pending publication to pub.dev. To use the newest release in the meantime, depend on the git tag directly:

dependencies:
  livetennisapi:
    git:
      url: https://github.com/livetennisapi/livetennisapi-dart.git
      ref: v1.2.1

Usage #

import 'package:livetennisapi/livetennisapi.dart';

Future<void> main() async {
  final client = LiveTennisApi(apiKey: 'twjp_your_key');
  try {
    final page = await client.listMatches(status: MatchStatus.live);
    for (final match in page.data) {
      final s = match.score;
      final (g1, g2) = s?.gamesForSet(0) ?? (null, null);
      print('${match.tournament} [${match.tour}]: '
          '${match.p1?.name} vs ${match.p2?.name} '
          '(${g1 ?? '-'}-${g2 ?? '-'}, serving: ${s?.server ?? '—'})');
    }
  } on UpgradeRequiredException catch (e) {
    print('Needs the ${e.requiredTier} tier');
  } on RateLimitedException catch (e) {
    print('Slow down; retry after ${e.retryAfter}s');
  } finally {
    client.close();
  }
}

Authentication #

Pass your twjp_ key to the constructor. By default it is sent as Authorization: Bearer <key> (preferred); pass authHeader: AuthHeader.xApiKey to use the X-API-Key header instead. (The API also accepts ?token= for header-less contexts such as raw WebSocket connections; this client always uses headers.)

final client = LiveTennisApi(
  apiKey: 'twjp_your_key',
  authHeader: AuthHeader.xApiKey,
  timeout: const Duration(seconds: 20),
  maxRetries: 3,
);

Endpoints #

Full parity with the documented public v1 REST surface:

A call above your tier throws UpgradeRequiredException, whose requiredTier names the plan that unlocks the endpoint.

Webhooks: up to 3 per key (a 4th is a 409 ConflictException, webhook_limit); the signing secret is returned once, on creation. Webhook registration is never auto-retried, so a transient failure cannot create a duplicate. getUsage reports quota state but not the daily reset instant — that arrives only as resetsAt on a daily 429.

Deliberately excluded: anything outside the documented public v1 JSON contract — undocumented gateway alias routes, server-rendered HTML views, and static assets (fonts, images). Package file downloads (/history/packages/{period}?format=) stream as attachments; this client returns the JSON manifest and leaves the download to your HTTP tooling.

Quotas #

The FREE tier is 100 requests/day, so poll no faster than every 15 minutes on a free key; for an always-on dashboard, BASIC is the recommended floor. Every response carries X-RateLimit-Limit / -Remaining / -Reset headers. When the daily quota is spent, the thrown RateLimitedException has scope == 'day' and resetsAt — the absolute reset instant (derived from the service's local midnight, so don't assume a fixed UTC hour). An AbuseThrottledException (24-hour block for broken retry loops) is never auto-retried; fix the loop and wait until retryAt.

Reading a score #

Score.games is player-major: [[games_p1...], [games_p2...]], each side a per-set list that grows as the match plays. Use gamesForSet rather than indexing by hand:

final (p1, p2) = score.gamesForSet(0); // games in set 1, as (p1, p2)

Score.points are strings ("0", "15", "30", "40", "AD"), and Score.server is 1, 2, or null.

History, head-to-head and the tape #

// The point-by-point tape — works on live matches too. The clean sequence
// carries pointWinner per attributable row, plus per-set tiebreak scores.
final tape = await client.getMatchTape(24101, sequence: TapeSequence.clean);
print('${tape?.meta?.coverage}: ${tape?.tape.length} rows');

// Head-to-head across the archive (1968–2022) and current matches (2023→).
final h2h = await client.getHeadToHead(p1: 'alcaraz', p2: 'sinner');
print('${h2h?.p1Name} ${h2h?.totals?.p1Wins}–${h2h?.totals?.p2Wins} '
    '${h2h?.p2Name}');

// Point-in-time rankings (ULTRA per-player mode), with previousRank.
final ranks = await client.listRankings(
  players: [501],
  asOf: '2026-08-03',
  systems: [RankingSystem.atp],
);

Tape coverage is honest, not guessed — read MatchTape.meta (coverage, pointSource) before backtesting, and note archive people live in their own id space, keyed by name.

Pagination #

await for (final player in client.paginate(
  ({limit = 200, offset = 0}) =>
      client.searchPlayers(search: 'nadal', limit: limit, offset: offset),
)) {
  print(player.name);
}
