Keyword Tool API vs Keywords Everywhere (2026): which should you pick?

Pick Keyword Tool API if

• Fits if you want Google and Bing search volumes pulled into your own tools or warehouse
• Works for long-tail research on YouTube, Amazon and TikTok as well as Google

Look elsewhere if

• Not for you if you want to try it first, as there's no trial, only a 30-day money-back guarantee
• Tight if you run many jobs, since Starter's 50 requests a day are shared with the web app and MCP
• Watch out: volumes for platforms other than Google and Bing are modeled estimates, not planner data
• Pricey if you pay monthly, at $88 against $68 on yearly billing

Pick Keywords Everywhere if

• Fits if you want keyword volume while doing ordinary Google or YouTube searches
• Works for Amazon and Etsy sellers who want to know what people search there

Look elsewhere if

• Tight if you search a lot, as one Google search showing 53 suggestions uses 54 credits
• Skip it if you want rank tracking or site audits, which it doesn't do
• Not for you if you want a web app, as Keyword Keg needs Gold at $480 a year
• Watch out: plans are yearly only, credits expire after 12 months, and volume and CPC vanish when they run out
• Too light for keyword research on the free version, which shows no search volume or CPC

Keyword Tool API

• The API needs a Keyword Tool Pro plan; there is no free trial, but every plan has a 30-day money-back guarantee.
• One daily request pool, from 50 on Starter to 400 on Agency, is shared by the web app, the API and MCP, and resets every 24 hours.
• Only Google and Bing volumes come from the ad planners; the other platforms' volumes are modeled estimates from clickstream data.
• A free Guest MCP gives Google and Bing suggestions with volume on the first 5 keywords, but no API access.

Keywords Everywhere

• It runs as a browser extension for Chrome, Firefox and Edge; Keyword Keg, the web-based tool, needs Gold at $480 a year.
• Plans are billed yearly only, and credits expire 12 months after purchase; once they run out, the extension hides volume and CPC.
• Credits go quickly: a single Google search that shows 53 suggested keywords uses 54 credits.
• Extra credits are sold as top-ups, from $80 for 200,000 credits (40 cents per 1,000) down to 16 cents per 1,000 in bulk.
