API Rate Limiting Best Practices for Esports Apps

// Bad: 10 requestsfor (const playerId of playerIds) {  await api.get(`/players/${playerId}`);} // Good: 1 requestconst players = await api.get('/players', {  params: { ids: playerIds.join(',') }});

// Instead of polling every 30 secondssetInterval(fetchLiveMatches, 30000); // Use webhooks (Starter plan and above)app.post('/webhook', (req, res) => {  const { event, data } = req.body;  handleMatchUpdate(data);  res.status(200).send('OK');});

const response = await api.get('/account/usage');console.log(`Used: ${response.data.requests_used}`);console.log(`Limit: ${response.data.requests_limit}`);
