Not to be confused with stabledomains.dev, an unrelated product run by a different company.[2]

StableDomains (also written StableDomains.net) is an online domain name registrar that sells, renews and manages ICANN domain names paid for in the USDC and USDT stablecoins, or by card. It describes itself as an "agent-first" registrar: every action available on its website is also exposed to software and AI agents through a REST API, the x402 payment protocol and a Model Context Protocol (MCP) server.[1][2] Domains are registered through an ICANN-accredited registrar partner.[2]

Overview

StableDomains offers registration in 432 domain endings, including .com, .net, .org, .ai, .io, .xyz and .co.uk.[1][8] Customers can buy as guests without creating an account, or sign in with an email link, a passkey or an Ethereum wallet (Sign-In with Ethereum).[1][8] The service is aimed at "AI agents and the developers who build them, and anyone who would rather pay for a domain in stablecoins than with a card".[2]

The company states that it is not affiliated with stabledomains.dev, and that its only website is stabledomains.net.[2] It lists web hosting, email hosting, SSL certificates and Bitcoin payments as outside its scope.[8]

History

StableDomains is based in England.[2] Its public changelog was introduced in an update dated 29 October 2026, which also added a one-request x402 registration endpoint (POST /api/v1/register), expanded the MCP server to 37 tools and published the /pricing and /agents.md pages.[11] As of November 2026 the API and MCP server were at version 2.5.0.[9][10] The company has announced a monthly "State of Agent Domains" report on domain drop statistics, with the first edition (covering November 2026) planned for early December 2026 under a CC BY 4.0 licence.[8]

Registration and renewals

A buyer searches for a name, which is checked for live availability and price. Creating an order locks the quoted price for 60 minutes and returns an exact amount and payment address; registration starts automatically once payment is confirmed.[1] Per-TLD registration, renewal and transfer prices are published in US dollars, payable at 1 USD = 1 USDC/USDT; as of November 2026 a .com cost US$16.99 for the first year and US$20.99 to renew.[3] Premium names are priced at the registry premium plus 12%.[8] Renewals can be paid per order or automatically from a per-domain "auto-renew vault" funded in USDC, which renews a name for one year when it is 30 days or less from expiry.[8] Domains can also be transferred in with an EPP authorisation code (adding one year), and up to 20 names can be registered with a single payment through a bulk cart.[8]

DNS, forwarding and DNS templates

Registered domains include hosted DNS (A, AAAA, CNAME, MX, TXT and NS records), custom nameservers and free 301 URL forwarding. One-call DNS templates configure a domain for Vercel, Netlify, GitHub Pages, Google Workspace, Microsoft 365 or Zoho Mail. SRV, CAA and ALIAS records are not offered on the hosted DNS.[8]

Privacy and checkout data

WHOIS privacy is included free on every registration where the registry allows it.[2] The company's guide to anonymous registration states that checkout has no registrant contact fields and supports guest purchases; buyers may add an email address to receive a receipt and recover orders.[1][8]

Expiring domains and Drop Radar

StableDomains publishes a feed of expiring, pending-delete and just-dropped domains (see domain name lifecycle), checked against live RDAP data and archive history. Its "Drop Radar" ranks names with a quality score drawn from sampled Wayback Machine snapshots, Common Crawl presence, brandability and spam heuristics, and offers presets, JSON and RSS feeds, and signed webhook alerts.[2][8]

Tools and guides

Free tools include a name generator, a domain value estimator, a WHOIS/RDAP lookup, a DNS and email-security checker (SPF, DKIM, DMARC) and a drop-date checker.[2] The site also publishes buying guides, including guides to choosing a TLD, buying a domain by card with an AI agent and registering a domain anonymously, plus a monthly domain-ending price report.[8]

Agent-first design

StableDomains is designed so that "everything a person can do in the UI an agent can do over the API or MCP".[2] Its interfaces include:

Agents can obtain a guest API key instantly without a form or email. The documented operating policy asks agents to re-check availability before buying, show the human the domain, price, token, chain and lock expiry, and obtain explicit confirmation before paying; card and Stripe Link payments always require a person's approval.[8][9] Account holders can set monthly spend caps, issue scoped read-only or no-purchase API keys and receive signed webhooks.[9] The site also hosts a moderated directory of AI agents and MCP servers.[4]

Payments

Orders can be paid in USDC or USDT on seven blockchains: Base, Ethereum, Arbitrum, Polygon, HyperEVM, BNB Chain and Solana. USDC is accepted on all seven and USDT where the token exists; payments of the exact amount to the order address are detected on-chain automatically.[1][2] On Base, USDC can also be paid gaslessly through an x402 payment header.[2] Card payments are taken through Stripe Checkout, with a card fee added at checkout, and agents can request payment through Stripe Link using the Machine Payments Protocol.[1][8] A prepaid USD balance can be topped up and used for registrations, renewals and auto-renewal.[2] See also buying a domain with crypto, x402, and the AI agent economy.

Affiliate programme

The StableDomains affiliate programme pays 30% of the company's margin (retail price minus wholesale cost) on paid registrations, renewals and transfers by referred customers within a 30-day attribution window, whether paid by card or in crypto; the card fee is excluded. Earnings of US$5 or more are batched each Monday, reviewed by an administrator and paid in USDC on Base. Self-referrals are blocked, the earliest referrer keeps the credit, and the programme is open to AI agents, which can pass a referral code in API and MCP order calls. A toolkit of banners, links and an embeddable search widget is provided.[7] The programme is compared with other registrars' schemes in Domain affiliate programs.
