How we rank

What the ranking is built on

Every provider here has a person enrichment endpoint in the looot catalog.
We rank by the cheapest price per lookup among a provider's person enrichment endpoints, read live from the catalog. A cheaper lookup ranks higher.
Some providers bill per call and some per person matched. One lookup returns at most one person, so the two prices compare, but a per-match provider charges nothing on a miss.
Free endpoints are not ranked, because a zero price says nothing about coverage.
The catalog does not publish a measured success rate for these endpoints, so this page does not rank by one and quotes none.
Providers outside the looot catalog are not ranked. Company enrichment from a domain is ranked on its own page.
