JavaScript runs first, so docs sites and single-page apps that a plain fetch returns empty come back complete. $0.009 per call (x402 on Arc/Base/Solana/X1): the full text and every outbound link. Without a payment the call returns the price and every rail we accept. Refuses private and reserved addresses and our own hosts, so it cannot be used as a proxy into a network. Sites that put a bot wall in front of their pages (Cloudflare, DataDome and the like) answer with a challenge rather than the page: the call then FAILS with `http-403` or `bot-challenge` and says so, rather than charging you for a spinner.",

Same host only; robots.txt is obeyed and anything it disallows is skipped and named. FREE: the crawl PLAN - exactly which pages would be fetched and what robots.txt allows - so you can see what you would get before paying. PAID ($0.14, x402 on Arc/Base/Solana/X1): every page rendered and returned. It costs more than one page because it is up to 25 real browser renders, not a lookup. If a bot wall on the site lets the first page through but blocks the rest, the call fails with `poor-yield` and names every page it could not render, instead of billing you for a list of failures.",
