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. - **Value for money: B.** Everything 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. - **Free plan and trial: A.** All listed APIs and tools are free outright, with no plan or trial to run out. - **Features: D.** Bot 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. - **Ease of use: C.** No store rating on record. Lists are easy to read, but using them as an API means calling them from your own code. - **Platforms and integrations: C.** Web pages and simple APIs only, with no integrations listed. These are ToolGPA's own grades. Graded from this listing, whose facts were read from SEOAPI.com's own page on 13 November 2026.

And it is not the kind of software a weekend replaces. - You could not: Speed tests run from real browsers on a schedule. - You could not: An API that other software can build on.
