This helps prevent server overload and ensures that all users have fair access to resources."},{question:"How do I avoid 429 Too Many Requests in Node.js?",answer:"Keep request bursts below the API limit, queue jobs with a rate limiter, batch large workloads, and retry only after honoring the Retry-After header."},{question:"How can I rate-limit Geoapify geocoding requests?",answer:'Use <a href="https://www.npmjs.com/package/@geoapify/request-rate-limiter" target="_blank" rel="nofollow noreferrer">@geoapify/request-rate-limiter</a> to wrap Geoapify geocoding calls, process them in batches, and keep the request rate within your plan limits.'},{question:"What rate limit should I use for Geoapify geocoding?",answer:"Start below the documented limit for your plan, then tune the rate based on batch size, traffic bursts, and how often you need to retry failed requests."},{question:"What does API rate limit exceeded mean?",answer:"When an API rate limit is exceeded, the client has made too many requests within a specific time window, which typically triggers a 429 Too Many Requests response."},{question:"Should I retry immediately after a 429 error?",answer:"No. Retry only after the delay specified by Retry-After, or use exponential backoff if the API does not send that header."},{question:"What is the difference between rate limiting and concurrency limiting?",answer:"Rate limiting controls how many requests you send over time, while concurrency limiting controls how many requests run at the same time. Many workloads need both."},{question:"Can I use @geoapify/request-rate-limiter with fetch or axios?",answer:"Yes. Wrap each fetch or axios call in a function that returns a promise, then pass those functions to the limiter."},{question:"How do I batch geocoding requests safely?",answer:"Split large address lists into smaller batches, save intermediate results after each batch, and make retries idempotent so you do not repeat already completed work."},{question:"Which NPM package helps with request throttling?",answer:'For Geoapify geocoding workloads, <a href="https://www.npmjs.com/package/@geoapify/request-rate-limiter" target="_blank" rel="nofollow noreferrer">@geoapify/request-rate-limiter</a> is a good fit because it handles request pacing and batch completion callbacks.'},{question:"What should I do if I still get 429 errors after throttling?",answer:"Lower the request rate further, increase batching, verify that your retries respect Retry-After, and check whether another part of your app is sending requests in parallel."},{question:"What is the 429 Too Many Requests error?",answer:"The 429 Too Many Requests error is an HTTP response status that indicates a client has exceeded the rate limit for API requests and must wait before making more requests."}]}))}var l=function(e={}){const{wrapper:t}=Object.assign({},(0,a.RP)(),e.components);return t?s.createElement(t,e,s.createElement(r,e)):r(e)};function i(e,t){throw new Error("Expected "+(t?"component":"object")+" `"+e+"` to be defined: you likely forgot to import, pass, or provide it.")}var o=n(4794),c=n(5588),p=n(8154),u=n(1574),m=n(7127),g=n(1543),h=n(3428),d=n(369),f=n(2992),k=n(3481),y=n(9911),w=n(9856),E=n(529),b=n(8818),v=n(1435),q=n(5898),I=n(2389),A=n(118),P=n(2833),x=n(9816),R=n(3008),T=n(3960),N=n(7358),_=n(6649);
