JSON is a lightweight, text-based format that represents data as key-value pairs and arrays. Because it's easy for both humans and machines to parse, JSON is the default payload for most modern APIs.
Why JSON matters for data collectors
Compact: Smaller than XML—less bandwidth when scraping through proxies.
Native in JavaScript: Works seamlessly with Node.js and browser automation.
Schema-flexible: Lets APIs evolve without strict contracts.
Tip: When polling high-volume JSON endpoints, route each request through Proxied's 4G/5G mobile IPs to avoid API rate-limit bans and geoblocks.
