Find expert witnesses and medico-legal assessors in the United States and Australia. Reads 18 public directories (7 in the US, 11 in Australia, ABIME counted once), merges the same person across directories into one record, and maps every source's specialty tags to one taxonomy. Each row carries name, specialty, state or region, country, firm, practice site, phone, listing URL, and the sources that list the person. country accepts US and AU only: the public actor covers the United States and Australia and refuses a UK or Canadian request, so the run stops with an error on any other value. published_email is filled only when a source page printed an address; the actor never guesses an email. Several sources publish terms that restrict automated collection, reproduction, commercial use, or solicitation; the actor README lists each source's terms posture, and the use decision is yours. mode list returns every matching expert; mode feed returns only experts new, changed, returned, or removed since the last run on the same persistent store. Charges $0.004 per expert record, $0.01 per row with a published email, $0.002 per US row checked against NPPES when verifyNppes is on, and $0.00005 per actor start per GB of memory (one event at the 1024 MB default). Requires an APIFY_TOKEN and consumes Apify credits. Read only against the directories; it writes only to the named key-value store in your own Apify account.
