Best for free lists of search and AI crawler IPs
SEOAPI.com is a set of free lists of search engine and AI crawler IP addresses, plus a URL parser and a few small SEO tools. It is not a keyword, ranking or SERP data service. The pages we read give no rate limits, uptime promise or terms, and it is run by one consultant.
Who SEO API is for
- Fits if you need to check whether a visitor really is Googlebot or an AI crawler
- Works for technical SEOs who want a quick URL parser or HTTP status checker
Who SEO API is not for
- Not for you if you want rankings, keywords or SERP data: it does not provide them
- Watch out: no rate limits, uptime commitment or terms were stated on the pages we read
- Skip it if you need a company behind it: it is run by an individual consultant
- Too light for a team that needs support, as no support channel is listed
Why SEO API gets a 2.4
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- BValue for moneyEverything listed is free of charge, which beats the $11.40 mark for data APIs. But the lists are small reference data rather than a data service, so we stop at a B.
- AFree plan and trialAll listed APIs and tools are free outright, with no plan or trial to run out.
- DFeaturesBot IP lists, a URL parse API and a handful of tools such as an HTTP status tester. It does one narrow job and does not give keywords, rankings or search results.
- CEase of useNo store rating on record. Lists are easy to read, but using them as an API means calling them from your own code.
- CPlatforms and integrationsWeb pages and simple APIs only, with no integrations listed.

Keep SEO API, or make your own?
Keep it
SEO API is free, so making your own would save you nothing.
And it is not the kind of software a weekend replaces.
What you could not
- Speed tests run from real browsers on a schedule.
- An API that other software can build on.
What this rests on. SEO API’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
