# Introduction

> MCP, REST, and CLI tools for LinkedIn automation, signal detection, email finding, and centralized auth + billing, metered in credits and billed centrally.

## What is GTM Tools?

GTM Tools is an API platform that gives AI agents the building blocks of a modern go-to-market motion: LinkedIn automation, Reddit engagement, buying-intent signals, SMTP-verified email finding, and centralized auth + billing. We handle the sessions, proxies, providers, and metering so you can focus on the agent loop.

**GTM agents** can:

* Qualify accounts on real buying signals instead of guesses
* Find the right decision-maker and a verified way to reach them
* Read and write on LinkedIn and Reddit through a real logged-in account
* Pay for exactly what they use, with no human in the loop

Five tool categories, 64 tools, one auth boundary:

| Category       | What it does                                                    |
| -------------- | --------------------------------------------------------------- |
| **Billing**    | API keys, credit balance, card top-ups, auto-reload, invoices   |
| **LinkedIn**   | Search, profiles, companies, posts, jobs, DMs, invitations      |
| **Reddit**     | Read threads, post + comment, vote, DM via Reddit Chat          |
| **Enrichment** | Professional email (SMTP-verified), social handles, coordinates |
| **Signals**    | Buying intent: hiring, Trustpilot, social spikes, tech stack    |

## The problem with naked agents

Your agent can write outreach, schedule meetings, and qualify leads. But the moment it needs real data (a prospect's LinkedIn URL, a verified email, evidence a company is hiring SDRs), it stalls. The GTM stack was built for humans with seats and browsers:

#### No API for the GTM surface

LinkedIn's write API is gated to approved partners. Reddit blocks unauthenticated reads from datacenter IPs. Public data your agent can see in a browser is unreachable from a server.

#### Per-seat pricing

Sales-intelligence tools bill per seat per month on annual contracts. Agents don't have seats, and they don't run at human volume.

#### Human-shaped auth

Cookies, OAuth consent screens, 2FA prompts, sessions that expire mid-run. None of it was designed for a process to hold on its own.

#### Fragmented plumbing

A scraper here, an SMTP verifier there, a job board, a review site. Six vendors means six API shapes, six keys, six rate limits, and no MCP anywhere.

## The solution

GTM Tools is an API-first GTM provider designed for agents. Think of it as the stack you'd otherwise assemble yourself, with:

#### Agent-native infrastructure

**One key, three interfaces**: the same tool over [MCP](/integrations/mcp), plain HTTP (see the [API Reference](/api-reference)), or the [CLI](/integrations/cli).

**Usage-based credits**: \$1 = 100 credits, \$5 minimum, 100 free to start. Plans add an included monthly pool; usage beyond it draws the balance.

**Pooled browser sessions**: the [browser extension](/extension) shares your real logged-in LinkedIn, Reddit, and Google sessions, encrypted at rest, refreshed automatically.

**Self-registration**: agents bootstrap their own credentials through [auth.md](/integrations/agent-onboarding), no human signup.

**A uniform error contract**: every failure is an HTTP status with a documented recovery, including an explicit retry signal. See the [Error Reference](/errors).

#### GTM-native capabilities

**Buying signals**: hiring, Trustpilot sentiment, follower spikes, and tech-stack detection, each one both a reason to reach out now and the angle to write about.

**Read and write**: not just lookups. `send_linkedin_message`, `send_linkedin_invitation`, `create_reddit_comment`, and `send_reddit_message` act as your own account.

**Verified emails**: `get_email` speaks SMTP up to `RCPT TO` and never sends mail, flagging catch-all domains so your agent knows when to trust the result.

**Boolean title filters**: `"(VP OR Director OR Head) AND \"customer success\" NOT intern"` narrows an employee search before you spend credits hydrating it.

**Agent Skills**: [three published skills](/skills/outbound-sales) teach an agent the whole workflow, not just the endpoints.

Get a key with `get_api_key` (or `gtm-tools admin login`) and the first call works immediately: new accounts start with 100 free credits. Email [support@gtm-tools.sh](mailto:support@gtm-tools.sh) if you run into anything.
