When does this happen?

IF Brave Local Search tool makes parallel API requests without throttling, exceeding API key rate limits.

How others solved it

THEN Implement request throttling, such as a queue with a configurable delay between calls. Monitor the rate limit headers in API responses to dynamically adjust the delay and avoid exceeding limits.

// Example throttle wrapper: const throttle = (fn, delay) => { let last = 0; return async (...args) => { const now = Date.now(); const wait = delay - (now - last); if (wait > 0) await new Promise(r => setTimeout(r, wait)); last = Date.now(); return fn(...args); }; }; const throttledGetPois = throttle(getPoisData, 1000); const throttledGetDescriptions = throttle(getDescriptionsData, 1000);
