ScrapingBee render_js defaults to TRUE - static pages silently cost 5 credits unless you opt out

TL;DR

Set renderjs=false explicitly for plain HTML targets. Static-page scrapers that never set renderjs=false pay 5x on every call for rendering they never needed.

Steps

1. ScrapingBee bills you 5 credits per request unless you say otherwise: renderjs defaults to TRUE, the opposite of most scraping APIs. Static-page scrapers that never set renderjs=false pay 5x on every call for rendering they never needed. Audit your requests: static HTML gets renderjs=false (1 credit), JS pages get renderjs=true (5). And know the proxy ladder before escalating: premium is 25 with JS, stealth is 75 and breaks some features like infinite scroll.

Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.

Source: ScrapingBee gotcha (documented in proxlane's integration docs): renderjs defaults to TRUE at 5 credits per request - the opposite default from ScraperAPI. If you omit it on static pages, every request silently costs 5 credits instead of 1. Set renderjs=false explicitly for plain HTML targets. Related cost tiers from the same docs: premiumproxy is 25 credits with JS (10 without), stealthproxy is 75 credits and requires JS - and stealth is incompatible with some features like infinite_scroll.
