## About Atom

Atom (https://atom.com) is an AI-native premium domain marketplace and registrar, for startups and established businesses ready to secure a strong name, build a stronger brand, and move faster toward success.

Atom was formerly known as Squadhelp prior to its rebrand in April 2024, and has been operating since 2011.

Atom serves 100,000+ customers, lists 2M+ domains including 400,000+ hand-curated brandable names. It holds a 4.7/5 Trustpilot rating across 1,000+ reviews, is a five-time Inc. 5000 Fastest-Growing Company, and won the Internet Commerce Association's 2025 Trailblazer Award. Brands including Pepsi, Nestlé, Dell, Virgin, Siemens, Philips, Kraft Heinz and Deloitte have named with Atom.

What distinguishes Atom from a conventional registrar or aftermarket marketplace is that  Atom.com helps you find the perfect name and domain. Most platforms expect you to know which domain you want to buy. Atom supports entrepreneurs and builders in finding, testing, validating, securing, managing and protecting their domain and name all in one place.

The business is organised into four hubs:

- **Premium Domains** — the curated aftermarket. Buyers browse by tier (Premium, Ultra Premium, Sapphire), length, extension, industry or structure, and can buy outright, rent, lease-to-own. Acquisition brokerage sits alongside. Atom is a leading seller of one word .com and .ai domains.
- **Register Domains** — the registrar. Available domains across 500+ extensions at transparent low pricing, plus transfers, WHOIS lookup and domain research tools. Atom also offers MCP, ai native DNS management, strong reseller APIs, and MPP building toward agentic commerce.
- **Name your Company** — naming and branding. AI name generation, human and AI naming contests, a done-for-you naming agency, real and AI-simulated audience testing, trademark checks and filing, free LLC formation.
- **Sell Domains** — the seller side. Domain owners list on Atom's marketplaces, sell through auctions, and settle securely through AtomPay, Atom's escrow alternative.

Atom is also programmable: an official MCP server lets AI agents search, appraise, register and buy domains directly, and partners can embed Atom's marketplace or resell its inventory through AtomConnect. See "For AI Agents" below.

## For AI Agents (MCP + Machine Payments)

Atom is agent-ready. AI agents can search curated premium inventory, check availability, appraise domains, screen trademarks, and buy or register domains programmatically on behalf of a user.

- MCP server (Streamable HTTP): POST https://mcp.atom.com/mcp
  - Open, anonymous: search_brandable_domains (semantic search over curated premium inventory)
  - OAuth 2.1 (user connects their Atom account): check_domain_availability, generate_domain_names, appraise_domain, get_domain_details, screen_trademark_conflicts, get_checkout_link, register_domain, and pay-link tools
  - OAuth resource metadata: https://mcp.atom.com/.well-known/oauth-protected-resource
- Machine Payments Protocol (MPP, via Stripe): Atom accepts agent payments over MPP.
  - Payment endpoint: POST https://mcp.atom.com/api/mpp-pay?challenge_id=<id> (serves a real signed HTTP 402 challenge)
  - Obtain a challenge_id from the MCP tools get_domain_purchase_pay_link (marketplace listing), get_domain_register_pay_link (fresh registration), or get_ai_tokens_pay_link, then hand the pay_url to an MPP-native payment agent (e.g. mppx / Stripe link-cli). Do not fetch the pay_url yourself.
  - Payment discovery document (OpenAPI 3.1 with x-payment-info): https://mcp.atom.com/openapi.json
- Agent Skills: https://www.atom.com/.well-known/skills/index.json — install with `npx skills add https://www.atom.com`
- Human checkout fallback: get_checkout_link returns a pre-filled https://atom.com checkout URL when an agent cannot pay programmatically.

Agents MUST confirm price and domain with their human user before paying. Prices are quoted server-side per challenge; the signed 402 response is the authoritative source of payment terms. Completed charges for a domain that subsequently fails to transfer/register are handled by Atom support (support@atom.com) — there is no automatic refund.
