SEO APIs sell metrics, crawls, and keyword rows as endpoints. Buy one if you are building a product. Do not buy one if you still do not know what to fix on your own site.
What an SEO API is for
An API fits a company that will store the response, design a UI, and maintain the integration. Rank tracking, backlink pulls, and keyword volumes are reasonable API jobs. You are becoming a light SEO vendor. Budget for that.
What people actually needed
The search for a best SEO API often starts because a suite felt heavy. An API is heavier. Someone has to call it, handle errors, and explain the JSON. The page is still broken at the end unless you write that layer.
The diagnosis instead
Fix SEO Today does not offer a public SEO API. The product crawls your site and writes the fix list. If you are building a platform and truly need endpoints, keep shopping for an API. If you need the site fixed, start the check.
No public SEO API. If you need a feature inside the product, email hello@fixseotoday.com. We ship product features in 2 days. We do not promise a developer platform.
Which SEO API is best in 2026?
The one whose data you will actually store and whose terms allow your use. That is a build decision. It is not a substitute for a crawl of your site.
Why is Fix SEO Today cheaper?
SEO APIs from Ahrefs, Semrush, and Moz are extremely expensive. You rent credits for an index. Fix SEO Today is cheaper because you pay for the diagnosis. A free peek, then $19 a month for one project or $99 a month for unlimited projects. That covers the crawl and the plain-English fix list, including GEO. It leaves out the backlink index, the rank-tracker seats, and the ads module.
