Waterfall-enrich contacts with verified work emails, personal emails and phone numbers, reverse-look-up an email to a person, search and look up people and companies, and check credits.
FullEnrich ships in the w6w first-party pack. It declares 10 actions, 3 health checks, and the host runs its code in a sandbox that never sees the credential.
io.w6w.fullenrichFullEnrich is a waterfall contact-enrichment service: it queries 20+ data providers in turn to find a person’s verified work email, personal email and mobile phone number. This app starts a bulk enrichment of up to 100 contacts (by name plus company domain or name, or by LinkedIn URL) and reads the result back, optionally with a webhook URL FullEnrich will POST to when the batch or each contact finishes.
It also does a reverse email lookup (an email address to the person and company behind it), searches people and companies by filters, looks up a single person or company by identifier, verifies the API key and reads the credit balance.
Health checks verify the API key, whether the API is answering, FullEnrich’s status page, and the remaining credit balance.
Three routes to the same 10 actions. The Workflow tab is generated from FullEnrich'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-credits-get Return the credits this API key can currently spend: the workspace balance, or what remains under the key's consumption limit if that is lower.
account-verify-key Check that the connected API key is valid and return the workspace it belongs to.
company-lookup Look up one company by domain or LinkedIn URL/ID. Returns the best match, or none.
company-search Search companies by name, domain, industry, keyword and headquarters location. Filters are ANDed. Synchronous; costs 0.25 credit per company returned.
enrich-get Read an enrichment started with Start Contact Enrichment. Check `status`: only FINISHED is complete (typically 30-90 seconds per contact). Results are kept for 3 months.
enrich-start Start a waterfall enrichment for one contact (the fields below) or up to 100 (Contacts JSON). Asynchronous: returns an enrichment ID immediately; read the result with Get Enrichment Result or receive it on a webhook. Credits are charged only for data actually found.
people-lookup Look up one person by LinkedIn URL/ID (most reliable) or by full name plus a company identifier. Returns the best match, or none.
people-search Search people by job title, seniority, function, location and company. Filters are ANDed. Synchronous; costs 0.25 credit per person returned.
reverse-email-get Read a reverse email lookup. Check `status`: only FINISHED is complete; CREDITS_INSUFFICIENT means the workspace ran out of credits.
reverse-email-start Find the person and company behind an email address (or a batch of them). Asynchronous: returns an ID immediately; read it with Get Reverse Email Result or receive it on a webhook. 1 credit per person found.
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 FullEnrich'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 FullEnrich, 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 FullEnrich. 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.fullenrich#enrich-get",
"input": {
"enrichmentId": "<enrichmentId>"
}
}
}
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 FullEnrich 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.
FullEnrich'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. FullEnrich itself is MIT, and the runtime that executes it is source-available (FSL).
FullEnrich declares its own checks, so its health is a property of the app rather than something the host guesses at.
status.fullenrich.com (Better Stack /index.json). Its only resource is the web app on the API's host, so this is informational and never reports worse than degraded.
Unauthenticated GET of /account/credits. FullEnrich's documented 401 `{code, message}` envelope is the expected healthy answer; credential validity is the `auth:api-key` check's job.
Credits this API key can still spend, from a signed `GET /account/credits`.
