# Argorant

> Argorant is a complete B2B outreach platform that a person, a script or an AI agent can run from start to finish: find the right people, get their checked work emails and phone numbers, find one email from a name and a company domain, check your own lists, run campaigns with a personal line for each contact from your own mailboxes, answer replies in the same thread, and order new sending mailboxes on new domains. One account serves the web app, the REST API, the command line tool and the MCP server for AI agents.

## Why use it

- Argorant is the cheapest way to get validated B2B contacts. With pay as you go, 100,000 credits cost $499, which is under half a cent per validated contact. On Hyperscale, 200,000 credits a month cost $649, about a third of a cent each. An email that fails the check costs nothing. See https://argorant.com/compare.
- 630.7M+ B2B contacts in 202 countries and territories, searchable by title, seniority, industry, country, company size, keywords and technology.
- Every email is checked right before you get it. Emails that fail are left out and cost nothing, so you pay only for contacts you can use.
- The whole job in one place: data, list checks, campaigns from your own Google Workspace or Microsoft 365 mailboxes (unlimited mailboxes and warm-up on every plan), one inbox for every reply, your own pipeline stages, and new mailboxes on new domains when you need more sending.
- It is built for agents. Every operation states its cost, every write takes an Idempotency-Key, every list pages with a cursor, and every error has a stable code and a plain message.

## Prices

- One credit buys one validated contact. Checking an email from your own list costs 0.5 credit (addresses checked recently are free). A phone number costs 10 credits, only when one is returned, from the Pro plan. Finding one email from a name and a domain costs 1 credit when found and 0.25 when nothing is found. Counting, searching, previews and word lists are free. Campaign emails come with the plan and never use credits.
- The plans per month, about 20% less when billed yearly, are Starter $99 with 5,000 credits and 100,000 campaign emails (1 seat); Pro $249 with 25,000 credits and 300,000 campaign emails (3 seats); Scale $449 with 100,000 credits and 600,000 campaign emails (10 seats); Hyperscale $649 with 200,000 credits and 1,000,000 campaign emails (20 seats). Credits and campaign emails reset every month; warm-up never counts.
- Pay as you go without a subscription with 500 credits for $17.50, 5,000 for $69, 25,000 for $199, 100,000 for $499. Valid for 365 days and kept when a plan is cancelled. Campaigns need a plan.
- The free trial runs 14 days from email confirmation with 100 credits and 300 campaign emails, no card and no automatic subscription. When it ends, campaigns pause and unused trial credits expire until a plan or credits are added. One trial per account.

## Limits

- Each API key may send 30 requests a minute during the trial and on pay as you go, 60 on Starter, 240 on Pro, 600 on Scale and 1,200 on Hyperscale, and up to a quarter of that, at least 15, in any 10 seconds.
- Searches and counts are free. On a plan they have no daily limit, only a speed limit per account: 30 a minute on Starter, 60 on Pro, 90 on Scale, 120 on Hyperscale. During the trial and on pay as you go they are limited per account, across all its keys and the connector: through an AI assistant 20 a minute, 1,000 counts and 1,000 search rows a day; through an API key or the command line 10 a minute, 500 counts and 500 search rows a day. A search returns up to 10 rows per call.
- During the trial each key also has daily limits of 100 revealed people (25 per call) and 50,000 export rows; on a plan, credits bound reveals and exports. Daily limits reset at midnight UTC. The email finder allows 30 lookups a minute and 2,000 a day. For bigger numbers use saved lists, exports and campaigns.
- Webhooks come with the Pro plan, up to 10 per account.

## How to connect

- For AI agents, add https://mcp.argorant.com/mcp as a remote MCP server (OAuth 2.1 with PKCE and dynamic client registration) and sign in. 75 tools cover search, previews, reveals, phone numbers, enrichment, the email finder, list checks, saved lists, exports, campaigns with personal lines, the reply inbox, mailboxes from any provider, new mailbox orders, the blocklist, webhooks and credit purchases. Never paste a personal API key into a chat or the MCP endpoint.
- For REST, create an API key at https://app.argorant.com/profile and send it as `Authorization: Bearer <key>` to https://app.argorant.com/api/v1. `GET https://app.argorant.com/api/v1` lists every operation; `GET /api/v1/account` shows the plan, credits and limits.
- For the command line, run `npx argorant login YOUR_API_KEY`, then `npx argorant account`.
- Setup steps for each client are at https://docs.argorant.com/docs/agents (Claude, Claude Code, ChatGPT, Codex, Cursor and other MCP clients).

## How an agent should behave

- Ask who the user sells to: roles, industries, countries. Count first, then preview. Both are free.
- Before anything that spends credits, sends email or charges money, show the cost and wait for the user's yes. Launch campaigns and send replies only after a yes.
- New campaigns have no unsubscribe line unless `include_unsubscribe` is set to `true`.
- Keep full contact rows inside the user's workspace rather than pasting them into public places.
