Overview

AI-generated overview

Searches a deduplicated directory of US and Australian expert witnesses and medico-legal assessors by specialty, region, country, and source.

What it does: Wraps the Mamba Labs Expert Witness Directory actor on Apify and exposes one tool, find_expert_witnesses. The tool filters records from 18 public US and Australian sources by specialty taxonomy codes, region, country, and source, returning one deduplicated row per person with all matching sources listed. Optional feed mode returns only new, changed, returned, or removed records since the last run, and an optional NPPES check adds NPI and status fields to US records.
When to use it: Use it when you need to locate expert witnesses or medico-legal assessors in the United States or Australia and want results filtered by specialty or region. It suits research, litigation support, and directory lookups where a single normalized taxonomy across sources is useful.
Requirements: Runs locally via npx as an npm package over stdio, so Node.js is needed. Requires an Apify account and an APIFY_TOKEN environment variable. Runs are billed per event on Apify, and feed mode needs a named key-value store in that account.

Before you install

Runs cost money on Apify: per expert record, per published email returned, per NPPES check, and a small actor-start charge. The APIFY_TOKEN is a secret. Several sources publish terms restricting automated collection, reproduction, commercial use, or soliciting listed people; the actor reports those terms but does not decide for you. Only US and Australian records are available, and uncapped runs may exceed the run timeout.

Coverage

The actor returns records for the United States and Australia only.
It reads 18 public sources: 7 in the US and 11 in Australia, counting ABIME once in the US. ABIME lists experts in several countries; the actor keeps only its US and Australian records.
UK and Canadian records are not offered. The country input accepts US and AU only, because the public actor refuses any other country and stops the run with an error.
The same person on several directories comes back as one record listing every source.
Every source's own specialty tags map to one taxonomy, so "Forensic Psychiatry" and "Psychiatrist, general adult" filter together.
Australian panel sources print the panel's contact details, not the doctor's, so those records carry a name, specialty, and state but no email.

Emails

The actor never guesses an email. published_email is empty unless a source page printed an address, and email_source names the page.

Source terms

Several sources publish terms that restrict automated collection, reproduction, commercial use, or soliciting the people they list. The actor README gives the terms posture of each source as it was published when the actor was built. The actor reports the terms; it does not decide for you. Make your own call for your use case, and take legal advice where it matters.

Tool

`find_expert_witnesses`

Find expert witnesses and medico-legal assessors in the United States and Australia, filtered by specialty, region, country, and source.

Input	Type	Required	Notes
`specialty`	array	no	Taxonomy codes, for example `medicine.psychiatry` or `engineering.structural`. A parent code also matches its children: `medicine.psychiatry` includes `medicine.psychiatry.forensic`. Empty returns every specialty. 55 codes.
`region`	array	no	State or region as the source prints it, for example Queensland, California, New South Wales. Case and accents are ignored. Empty returns every region.
`country`	array	no	`US`, `AU`, or both. Empty returns both. No other value is accepted: the public actor refuses a UK or Canadian request and stops the run.
`sources`	array	no	Directories to read. Empty reads the 18 implemented sources: `abime`, `lacourt-panels`, `sfbar`, `cccba`, `isba`, `lsba`, `aaimco`, `medilaw`, `lexmedicus`, `aushub`, `medicolegal-specialists`, `index-medicolegal`, `themis`, `integrityml`, `vmls`, `lime`, `mag-directory`, `workcover-wa`. The other 17 values the actor offers are planned or not covered; the actor skips them and names them in its `RUN_SUMMARY` record.
`mode`	string	no	`list` (default) returns every matching expert. `feed` returns only experts that are new, changed, or returned since the last run on the same persistent store, plus removed rows. Unchanged experts are not emitted and cost nothing.
`verifyNppes`	boolean	no	Off by default. Checks each US record against the free NPPES monthly file and adds `npi` and `nppes_status`. NPPES carries no email.
`maxItems`	integer	no	Stop after this many output rows. Default 100. `0` means no cap. A capped run never marks listings as removed.
`persistStoreName`	string	no	Named key-value store in your Apify account that keeps expert records between runs. Default `expert-witness-directory-store`. Reuse the same name for feed mode.

Nothing is required. A call with no inputs reads all 18 sources and returns up to 100 experts.

A run with maxItems: 0 reads every listing on every source at one request per 2 seconds per host. It has not been timed, and it may pass the 3,600 second run timeout this wrapper sets. Set maxItems for an interactive call.

Pricing

Expert Witness Directory is pay per event on Apify. Four events are billed.

Event	Charged for	Price	Fires when
`expert-record`	Expert record	$0.004	Once per deduplicated expert row written to the dataset. In feed mode, once per new, changed, returned, or removed row; unchanged experts are not emitted and cost nothing.
`email-found`	Email returned	$0.01	Once per row that carries a published email a source page printed. Removed rows never charge it.
`npi-verified`	NPPES check	$0.002	Once per US row checked against the NPPES monthly file. Only when `verifyNppes` is on.
`apify-actor-start`	Actor start	$0.00005	Charged by Apify when the run starts, one event per GB of memory. One event at the 1024 MB default.

Actor

Actor ID LIpwlgfE3LaQBaXd4. The wrapper calls the actor by that immutable ID rather than by its Store slug, so a Store rename never breaks it.

Built by Mamba Labs.
