Our own Rust extraction engine. When a selector breaks, adaptive rules relocate the element by structural similarity and report confidence. Uncertain matches return no values rather than a guess.
How adaptive selectors work →Secure by default
Outbound requests are validated, DNS answers are pinned, and private, loopback and metadata ranges are blocked. Every redirect is re-checked, and robots.txt and per-domain pacing are respected.
Security model →Transparent limits
Free means quotas, not surprises: 20 units a minute and 100 a day per account. Responses state what was measured and what wasn't.
