The sites
How results come back
When Spidra cleans a link (removing tracking parameters or following a short link), the result has
canonicalUrl; url stays the link you sent.
Every site page lists the links that work and the fields you get. Most fields are optional on the site’s side, so a missing value comes back as null or an empty list, never a guess.
What’s free
A link that can’t be read costs nothing: a page that doesn’t exist, a page that needs a sign-in, a search with no results, or a page the site wouldn’t serve. The result says why in plain words.When the browser is used instead
These links are read in a normal browser scrape (with the usual cost) when you ask for something only a browser can do:- a screenshot (
screenshotorfullPageScreenshot); - browser
actionsor aninstructionon the URL.
