Competitors are found from the keywords a target actually shares with other domains, surfacing your real organic rivals rather than the brand competitors you'd guess from memory.
Each competitor returns the number of keywords it shares with your target, so you can rank rivals by how directly they compete with you in search.
Every discovered competitor includes its organic traffic (ETV) and total keyword estimates, giving you a strength read on each rival in the same response.
The average rank across shared terms shows whether a competitor is beating you on the keywords you both target or merely overlapping at lower positions.
Pass ISO location and language codes to discover competitors in a specific market, since a domain's US and German organic rivals can be completely different sites.

console.log(data);The competitor analysis API — find any domain's real SEO rivals
YepAPI's Domain Competitor Finder API discovers the websites competing with any domain in Google organic search, ranked by keyword overlap. For each competitor you get the keyword-intersection count, organic traffic and keyword estimates, and the average position across shared terms — your real SEO rivals, identified from ranking data rather than guesswork, in one call.
Pass a bare domain and get a structured JSON list back, localized to any country and language. It answers 'who am I actually competing with in search?' and feeds straight into the rest of a competitive-research pipeline. At $0.02 plus $0.02 per 100 results with no monthly minimums, it's the cheapest way to auto-generate competitor sets for audits, dashboards, and niche maps under one API key.
What is a competitor analysis API?
A competitor analysis API returns a domain's organic-search rivals as data — discovered from shared keywords and ranked by overlap. That turns competitor research into something automatable: generate a competitor set for any domain on demand, then analyze each rival programmatically. YepAPI surfaces competitors from real keyword intersection and returns counts, traffic estimates, and average positions in a single call.
Build your own competitor research tool
Build a competitor-research or agency-audit tool on this endpoint. Discover a domain's rivals, then chain into the Domain Keywords API to pull their terms and the Domain Overview API to benchmark authority and traffic — a full competitive picture from three endpoints and one key. Auto-run it during client onboarding to generate competitor sets without manual research.
Competitor analysis API pricing — $0.02 + $0.02 per 100 results
Pricing is $0.02 per call plus $0.02 per 100 competitor results, so a 100-competitor scan costs about $0.04 — no subscriptions, seats, or minimums. Ahrefs and Semrush keep competitive data behind four-figure monthly or enterprise plans. YepAPI is pay-as-you-go with $5 of free credit, enough for many full competitor scans before you spend anything.
Map an entire niche's competitive landscape
Map a whole niche by looping the call across seed domains and merging the discovered competitors into one graph of who competes with whom. Intersection counts and traffic estimates show which players dominate and how contestable the space is. It's a programmatic way to judge market saturation before committing budget — or to keep a live map of your sector's competitive web.
