Search and enrich people and companies, and manage contacts, accounts, deals, sequences, tasks and lists in Apollo.io's sales intelligence and engagement platform.
Apollo ships in the w6w first-party pack. It declares 44 actions, 3 health checks, and the host runs its code in a sandbox that never sees the credential.
io.w6w.apolloApollo is a sales intelligence and engagement platform: a database of over 240 million contacts and 30 million companies, plus the CRM-style records (contacts, accounts, deals) and outreach machinery (sequences, tasks) sales teams run on top of it.
This app covers both halves. The database half is search and enrichment — find net-new people and companies by title, location, technology and dozens of other filters, or enrich a person or company you already have a name, email or domain for, individually or up to ten at a time. The CRM half is the records your team already tracks — create and update contacts, accounts and deals, move them through stages, enroll contacts in outreach sequences, and manage tasks and saved lists.
Every search endpoint accepts its filters as bracket-style query parameters even though it is a POST request (person_titles[]=CEO&person_titles[]=CTO), which is not how the rest of the API works and is easy to get wrong from outside a generated client. Enrichment and CRM-write endpoints take an ordinary JSON body instead.
Three routes to the same 44 actions. The Workflow tab is generated from Apollo'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-create Save a new company to your Apollo instance. No deduplication is applied — see the action's notes.
account-stage-list List every account stage configured for your team, for use with account-create/update and account-search.
contact-stage-list List every contact stage configured for your team, for use with contact-create/update, contact-stage-update and contact-search.
credit-usage-stats-get Read this team's credit balances for the current billing cycle.
deal-stage-list List every deal stage configured for your team's pipeline, for use with deal-create/update.
list-add-records Add contacts or accounts to one or more lists, creating any list name that doesn't already exist.
list-create Create a new list ("label"). The name must be unique for the given record type.
list-list Every list ("label") in your team's account — contacts, accounts, and sequence folders alike.
organization-bulk-enrich Enrich up to 10 companies in one call by domain, LinkedIn URL, name or website.
organization-enrich Look up and enrich one company's data by domain, LinkedIn URL, name or website.
organization-get Fetch one company from Apollo's database by its Apollo organization ID.
organization-job-postings-list List an organization's active job postings — a signal for hiring/growth.
organization-search Search Apollo's database of 30M+ companies. Costs 1 credit per page (up to 100 results/page).
people-bulk-enrich Enrich up to 10 people in one call by name, email, domain, LinkedIn URL or Apollo ID.
people-enrich Look up and enrich one person's data by name, email, domain, LinkedIn URL or Apollo ID.
people-search Search Apollo's database of 240M+ people for net-new prospects. Costs 0 credits and returns no email/phone — enrich a match afterwards to reveal contact details.
sequence-activity-list List a contact's sequence activity events (opens, clicks, replies, steps sent).
sequence-remove-contacts Mark contacts finished, remove them, or stop their progress across one or more sequences.
usage-stats-get Read this team's per-minute/hour/day usage and limits for every API route.
user-profile-get Fetch the identity of the user who owns this connection's API key.
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 Apollo'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 Apollo, 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 Apollo. 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.apollo#account-create",
"input": {
"name": "<name>"
}
}
}
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 Apollo 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.
Apollo'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. Apollo itself is MIT, and the runtime that executes it is source-available (FSL).
Apollo declares its own checks, so its health is a property of the app rather than something the host guesses at.
Monitor status from status.apollo.io (Better Stack): the web app and the async email/phone delivery pipeline that backs waterfall enrichment. No monitor is named for the REST API itself, so this is informational context, not a verdict on api.apollo.io.
Team-wide credit balances for the current billing cycle, from POST /usage_stats/credit_usage_stats — every credit type the plan meters, read generically.
Per-minute/hour/day headroom for GET /users/api_profile, read from Apollo's own x-rate-limit-*/x-*-requests-left response headers. Scoped to that one endpoint — see the module doc for why a blanket figure isn't available.
