Overview

Seamless.AI is a B2B sales-intelligence database: contacts with verified emails and direct phone numbers, and the companies they work for. This app covers its public API end to end.

The core path is search, then research. Searching contacts or companies by title, seniority, location, company size, revenue, technology or funding returns lightweight results; researching the ones you pick enriches them into full records. Research is asynchronous - one action starts it and returns request IDs, and a second polls until each record is done - so a workflow can fan out a lead list and collect the enriched rows when they land.

Around that sit the records your organization already owns - researched contacts and companies listed by date window and sorted into lists - plus saved searches, engagement campaigns and their metrics, tasks, templates, call logging and the activity feed. Credit balances are readable at any time, and a health check tracks the balance so a workflow can see the pool running dry before a 422 stops it.

Authentication is a single API key created under Settings > Public API in Seamless.AI.

Build with Seamless.AI

Three routes to the same 45 actions. The Workflow tab is generated from Seamless.AI'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.

List Activity

activity-list

The engagement activity feed: emails, calls and other events, optionally for one contact or campaign.

List Call Dispositions

call-dispositions-list

The dispositions a logged call can carry.

Log Call

call-log

Record a call against a contact.

List Call Sentiments

call-sentiments-list

The sentiments a logged call can carry.

Run Campaign Action

campaign-action

Start, pause, resume, complete, archive, unarchive or delete a campaign. START begins sending to its contacts.

Add Contacts to Campaign

campaign-contacts-add

Enroll researched contacts in a campaign.

List Campaign Contacts

campaign-contacts-list

List the contacts enrolled in a campaign.

Remove Contacts from Campaign

campaign-contacts-remove

Check research requests started by companies-research. A result is complete when its status is `done`; other states are `researching`, `missing` and `error`.

Search Companies

companies-search

Search the Seamless.AI company database by name, domain, location, size, revenue, funding and more. Spends credits: the vendor bills search results against your Seamless.AI credit balance.

List Contact Statuses

contacts-research-poll

Check research requests started by contacts-research. Poll every 2-5 seconds; a result is complete when its status is `done`.

Search Contacts

contacts-search

The user the API key belongs to: email and name.

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 Seamless.AI'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 Seamless.AI, 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 Seamless.AI. The Workflow tab is where this app's real ids are.

Install
npm install @w6w/sdk
yarn add @w6w/sdk
pnpm add @w6w/sdk
deno add npm:@w6w/sdk

import { W6wClient, isActionRun } from "@w6w/sdk";

const client = new W6wClient();

const envelope = await client.run({
  urn: "conn_YOUR_CONNECTION_ID",
  action: "call-log",
  payload: {
    contactId: "<value>",
    // toNumber: "<value>",

Give an AI agent Seamless.AI — without giving it Seamless.AI's credentials. 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.seamlessai#call-log",
    "input": {
      "contactId": "<contactId>"
    }
  }
}

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 Seamless.AI connections to sign with, and refuses rather than guesses when the answer is ambiguous.

What the agent gets

Credentials it can't read

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.

A tool surface scoped to the caller

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.

A durable workflow in one call

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.

Health-aware discovery

Seamless.AI'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. Seamless.AI itself is MIT, and the runtime that executes it is source-available (FSL).

Request MCP access

Health checks

Seamless.AI declares its own checks, so its health is a property of the app rather than something the host guesses at.

service

Seamless.AI platform status

No machine-readable status surface: status.seamless.ai is Cloudflare-gated (403) and seamless.statuspage.io is the unclaimed Statuspage shell.
