# DomainFind.ai

> The agent-first domain discovery gateway: real-time domain availability via RDAP,
> registrar price comparison across 5 registrars, and semantic name generation —
> exposed as a public Model Context Protocol (MCP) server, a keyless REST API,
> and a web search. Operated by AI Venture Holdings LLC.

Key facts:
- MCP server endpoint: https://domainfind.ai/api/mcp (streamable HTTP; tools: check_domain, search_domains, suggest_domains, get_tld_pricing)
- REST API base: https://domainfind.ai/api/v1 (keyless free tier: 50 req/day/IP; free keys: 500/day)
- Availability verification: RDAP primary (confidence >= 0.97), DNS-over-HTTPS fallback (~0.75); every answer labels its method
- Privacy: no identity-linked search logs, no query resale, no domain front-running
- Supported TLDs include: com, ai, io, app, dev, net, org, co, xyz, tech, so, gg, sh, me

## Use cases

- [Domain Registration Inside AI Coding Agents](https://domainfind.ai/use-cases/ai-coding-agents): Give your coding agent the ability to check, price, and hand off domain registration as a native step in automated project kickoff — over the Model Context Protocol.
- [Domain Search for Digital Agencies](https://domainfind.ai/use-cases/digital-agencies): Stop screen-sharing registrar tabs with clients. Run availability sweeps, price comparisons, and name generation through one API your project tooling can call.
- [Naming a Startup in the Agent Era](https://domainfind.ai/use-cases/startups): Describe the company in one sentence. Get back names you can register today — with honest pricing, .ai registry rules included, and zero front-running risk.
- [Programmatic Discovery for Domain Investors](https://domainfind.ai/use-cases/domain-investors): Sweep candidate names across TLDs programmatically, verify at the registry, and monitor pricing spreads — through an API built for volume.

## Glossary

- [RDAP (Registration Data Access Protocol)](https://domainfind.ai/glossary/rdap): The modern, HTTPS-based successor to WHOIS that returns structured JSON registration data.
- [WHOIS](https://domainfind.ai/glossary/whois): The legacy port-43 protocol for querying domain registration records, now superseded by RDAP.
- [Model Context Protocol (MCP)](https://domainfind.ai/glossary/model-context-protocol): An open standard that lets AI models call external tools and data sources through a uniform interface.
- [.ai Domain](https://domainfind.ai/glossary/ai-domain): Anguilla's country-code TLD, adopted globally as the signature extension for AI companies.
- [ccTLD (Country-Code Top-Level Domain)](https://domainfind.ai/glossary/cctld): A two-letter TLD assigned to a country or territory — some repurposed as global brands.
- [gTLD (Generic Top-Level Domain)](https://domainfind.ai/glossary/gtld): Extensions like .com, .net, .app, and .dev operated under ICANN policy.
- [Domain Front-Running](https://domainfind.ai/glossary/domain-front-running): The practice of registering a domain someone searched for before they can buy it.
- [Premium Domain](https://domainfind.ai/glossary/premium-domain): A domain priced above standard registration — by the registry or an aftermarket seller.
- [Domain Availability](https://domainfind.ai/glossary/domain-availability): Whether a domain can be registered right now at standard pricing.
- [Registry vs. Registrar](https://domainfind.ai/glossary/registry-vs-registrar): The registry operates a TLD's database; registrars sell registrations to the public.
- [Agentic Workflow](https://domainfind.ai/glossary/agentic-workflow): A multi-step process executed autonomously by AI agents calling tools, with humans supervising outcomes.
- [DNS-over-HTTPS (DoH)](https://domainfind.ai/glossary/dns-over-https): DNS resolution wrapped in HTTPS, used as a fast secondary availability signal.
