EstiBot

What it is

EstiBot (estibot.com) is a long-standing automated domain-name appraisal and research service for domain investors. It estimates value from search volume, CPC, comparable sales, extensions and more.

Key features

• Domain appraisal returning about 100 data points per domain.
• Bulk appraisal (paid levels).
• Lead generator, drop lists, zone-file differences (paid levels).
• API — available only to Advanced and Expert accounts; up to 200 domains per submission; cache vs live modes.

How to use it

1. Visit estibot.com (a bot check may appear).
2. Enter a domain as a guest — guests must now verify with Google, Facebook or Apple instead of a captcha.
3. Register for higher limits and bulk tools.

The full toolset (estibot.com, 2026-10-15)

• Domain Appraiser — automated valuation; bulk upload accepts text or CSV files with one domain per line.
• Lead Generator — finds end-user buyers (companies using the same keyword) to pitch a domain to.
• Whois Checker, Drop Lists and Expiring Domains — spot names about to drop or go to auction.
• Bid Tool, Word Parser and Trademark Analyzer — helps check if a name splits into real words and flags trademark risk.
• Domain Sales data, Portfolio Monitor, Idea Tool and Site Links.

How the appraisal works

EstiBot combines previous sales data, keyword data, CPC, type-in data and a statistical algorithm (see its methodology page). An API response includes a retail appraised value, a wholesale value, a monetization value, a value ignoring trademarks, a value without sales data, a category, language, word split and which other extensions (.net, .org, .info…) are already taken. The wholesale figure is the more realistic number when selling to other investors.

Automated vs professional appraisal

Automated appraisals come from the algorithm. EstiBot also sells professional appraisals done by human appraisers, and itself recommends ordering one if you need the true value of a specific domain. For portfolios of 5,000 to 100 million domains it offers portfolio appraisals.

API details

The API returns normalized JSON and is limited to Advanced and Expert accounts. Supported tools: Appraise, Lead Generator, Drops and Zone Difference. Query modes are live, cache or auto (cache is fastest). API queries count against your normal query limits. Current documentation has moved to GitHub (github.com/domainret/estibot-api), written for both humans and AI agents.

Pricing

Current plan prices sit behind the account-type comparison and could not be confirmed publicly.

Pros & cons

Pros

• Established, data-rich appraisals; API for automation.

Cons

• Automated values often differ from real sale prices — use as one signal only.
• Current pricing not publicly visible; free usage is very limited.

Best for

Domain investors who appraise and screen many names and want API access.

Alternatives

Verdict

Useful for screening domains at scale, but confirm current pricing in your account and never price a domain on an automated estimate alone.
