}Features
Pull every organic keyword a domain ranks for in one call — no crawling or scraping setup — so you can size a competitor's entire SEO footprint, not just their top terms.
Each ranked keyword returns its current Google position, monthly search volume, and CPC, so you can sort by traffic value and find a domain's most important terms instantly.
Every keyword includes the exact page that ranks for it, letting you group keywords by URL to find a competitor's strongest pages or build a redirect map before a migration.
Set the limit field to return anywhere from a handful of keywords to a full 1,000-row footprint, so you control cost — pricing scales at $0.02 per 100 results.
Pass ISO location and language codes to pull a domain's rankings for a specific market, since a site's US and German keyword sets can be entirely different.

console.log(data);The domain keywords API — see every keyword any domain ranks for
YepAPI's domain keywords API returns the complete list of search terms a domain ranks for in Google organic results — each with its position, monthly search volume, CPC, and exact landing URL. It's a ranked-keywords API for reverse-engineering competitor SEO: pass any domain, get up to 1,000 of its keywords back as structured JSON, localized by country and language.
Because every keyword ships with the URL behind it, you can group keywords by page to find a competitor's strongest content, diff portfolios for a keyword-gap analysis, or map redirects before a migration. At $0.02 plus $0.02 per 100 results, it's the cheapest way to add competitor keyword intelligence to an SEO tool, agency dashboard, or research pipeline — all under one API key.
What is a domain keywords API?
A domain keywords API returns the keywords a website already ranks for, rather than metrics for keywords you supply. You pass a domain and receive each ranking term with position, volume, CPC, and landing URL in JSON. That makes competitor keyword discovery automatable — pull a rival's footprint, diff it against yours, and surface gaps. YepAPI returns up to 1,000 ranked keywords per domain, localized to any market.
Build your own keyword gap tool
Build a keyword-gap or competitor-research tool on this single endpoint. Pull ranked keywords for several domains, diff the lists, and rank the gaps by volume and position to produce prioritized content recommendations. The landing-URL field lets you cluster keywords by page and reveal a competitor's top-performing content. Pair it with the Keyword Research API to score candidate terms and the SERP API to verify live positions.
Domain keywords API pricing — $0.02 + $0.02 per 100 results
Pricing is $0.02 per call plus $0.02 per 100 results, so 100 ranked keywords cost $0.04 and a full 1,000-keyword pull is about $0.22 — no subscriptions, seats, or minimums. Ahrefs and Semrush keep ranked-keyword data behind four-figure monthly or enterprise plans. YepAPI is pay-as-you-go with $5 of free credit, enough for dozens of full domain pulls before you spend a cent.
Reverse-engineer competitor SEO at scale
Reverse-engineer any competitor's SEO by pulling their entire ranked-keyword footprint and analyzing it programmatically. Sort by volume to find their biggest traffic drivers, group by URL to find their best pages, and diff against your own coverage to find what you're missing. Loop the call across a list of competitors to map an entire niche's keyword landscape from one endpoint.
