Find, enrich and prospect B2B contacts and companies, track buying signals, and manage signal webhooks through the Lusha API.
Lusha ships in the w6w first-party pack. It declares 24 actions, 3 health checks, and the host runs its code in a sandbox that never sees the credential.
io.w6w.lushaLusha is a B2B contact and company data platform used by sales and recruiting teams to find the right person at the right company and reach them. This app connects a workflow to the Lusha v3 API with an API key.
A workflow can look up contacts and companies by identifier (Lusha id, LinkedIn URL, email, name plus company, domain) to get a free non-PII preview, then reveal emails and phone numbers or extra firmographics for the ones it wants, or do both in one call. It can prospect for contacts and companies against an ideal customer profile with Lusha’s filters (and list the valid filter values), find lookalikes of a set of seed contacts or companies, read job-change and company signals such as hiring surges, headcount and IT-spend moves, and subscribe a webhook to signal events. When Lusha’s data waterfall hands back a job instead of a final answer, the app polls it.
Enrichment spends credits, so the app exposes the account’s remaining credits, rate-limit windows and per-action pricing, and its health checks track the credit and request headroom next to the API’s own status.
Three routes to the same 24 actions. The Workflow tab is generated from Lusha's own manifest and carries its real ids, so it is copy-pasteable; the Code and CLI examples are the same call for any action on any app, so every app-specific value in them is a blank you fill in.
account-usage Credits (total, used, remaining), daily/hourly/per-minute rate-limit windows, plan, and the credit price of each action. Limited to 5 requests per minute.
company-enrich Full company data for companies found by Company Search (up to 100 ids), plus optional paid extras (headcount breakdowns, competitors, intent, IT spend, parents).
company-filter-list The filter types Prospect Companies accepts, and whether each needs a search query.
company-filter-value-list Valid values for one company filter type, for building Prospect Companies filters.
company-lookalike Find companies similar to 5-100 seed companies (Lusha ids, domains or LinkedIn URLs).
company-prospect Find companies matching firmographic, technology, intent and signal filters. Page through with page/size.
company-search Look up companies by Lusha id, name or domain. Returns a preview with what can be revealed.
company-search-and-enrich Find companies and reveal their full data in one call. Spends credits.
company-signals Hiring, headcount, web-traffic, IT-spend and LinkedIn-intent signal events for up to 100 companies.
contact-enrich Reveal emails and/or phones for contacts already found by Contact Search (up to 100 ids). Spends credits; may return a `job` to poll with Get Contact Enrich Job.
contact-enrich-job-get Poll the async Data Waterfall job returned by Enrich Contacts. Poll every `retryAfter` seconds while status is processing; stop on complete, expired or failed. Polling is free.
contact-filter-list The filter types Prospect Contacts accepts, and whether each needs a search query to list its values.
contact-filter-value-list Valid values for one contact filter type, for building Prospect Contacts filters.
contact-lookalike Find contacts similar to 5-100 seed contacts. Seeds can be Lusha ids, LinkedIn URLs, emails, or name + company objects.
contact-prospect Find contacts matching an ideal-customer profile with contact and company filters. Page through with page/size. Use the filter-list actions to discover valid filter values.
contact-search Look up contacts by identifier (Lusha id, LinkedIn URL, email, or first + last name + company). Returns a non-PII preview with what can be revealed; no credits are spent on emails or phones.
contact-search-and-enrich Find contacts and reveal their emails/phones in one call. Same identifiers as Search Contacts. Spends credits.
subscription-create Subscribe a webhook URL to signal events for up to 25 contacts or companies.
subscription-delete Delete up to 25 webhook subscriptions by id; partial success is reported per id.
subscription-list Webhook subscriptions for signal notifications, newest first.
A workflow step names the app and the action, and the editor fills in the
connection when you pick one. This is the Step shape from the
workflow spec, carrying Lusha's real ids.

Every app-specific value here is a blank you have to fill in. An
app action is reached through the connection that authenticates it, so the
address is a connection id, not the app id — and connections belong to your account,
so a public page cannot know yours. Create one for Lusha, then fill in
the three blanks: conn_YOUR_CONNECTION_ID, the action key, and the
parameters that action declares. The call itself is real — the shape is transcribed
from the studio's own snippet builder, which prints the same kind of blanks — but
nothing in it is specific to Lusha. The Workflow tab is where this app's
real ids are.

One MCP endpoint exposes every app, function and workflow the caller is entitled to, as tools it can discover and run. Access is granted per team while we onboard.
One tool call{
"name": "w6w_invoke",
"arguments": {
"ref": "app:io.w6w.lusha#company-enrich",
"input": {
"ids": "<ids>"
}
}
}
Every tool names its target with a single ref. The
app: form above doesn't name a connection at all — the
host resolves which of the caller's Lusha connections to sign
with, and refuses rather than guesses when the answer is ambiguous.
The token is attached host-side, at the moment of the call. It is never a tool argument, never in the model's context, and never in a transcript — so a prompt injection has nothing to exfiltrate.
Tools are derived per end user from what that person has actually connected and is entitled to — not one shared bot identity carrying the union of everyone's access.
Multi-step work runs on the workflow engine and returns a run handle the agent can poll — retries, branching and state survive the conversation that started them.
Lusha's declared health checks are on the surface too, so an agent can tell "the vendor is down" from "your credential expired" before it burns a retry on either.
The MCP surface is part of the hosted platform. Lusha itself is MIT, and the runtime that executes it is source-available (FSL).
Lusha declares its own checks, so its health is a property of the app rather than something the host guesses at.
The `Lusha API` and `Prospecting` components of status.lusha.com.
Unauthenticated GET of /v3/account/usage. Lusha's documented JSON 401 is the expected healthy response; key validity is the `auth:api-key` check's job.
