}Features
Submit up to 200 keywords (one per line) in a single call, so your true SERP competitors are computed across a meaningful keyword set rather than one term at a time.
Each competitor returns a visibility score plus avgPosition and medianPosition, so you rank rivals by how dominantly they appear across your keywords.
The etv field estimates each domain's traffic from your keyword set, turning SERP presence into a comparable traffic figure for sizing competitors.
keywordsCount shows how many of your submitted keywords each domain ranks for, separating broad competitors from those overlapping on just a few terms.
The location and language fields scope the analysis to a market, so the competitor set reflects who ranks in the region you actually compete in.
Use cases

Market Entry Analysis
Before entering a new keyword space, analyze who already dominates to gauge competition difficulty and identify weak spots.

console.log(data);The SERP competitor API for developers — find who really ranks for your keywords
The SERP Competitor Analysis API takes up to 200 of your keywords and returns the domains that actually rank for them, each scored on visibility, average position, estimated traffic, and keyword overlap. It identifies your real organic competitors — the sites in your SERPs, not the ones you assume.
It is the discovery step in YepAPI's competitor suite. Once you know who you are up against, the Keyword Gap and SERP Overlap endpoints drill into exactly which terms and pages they win — all under one key.
What is a SERP competitor API?
A SERP competitor API determines who your organic rivals truly are by analyzing who ranks across a set of your keywords. You submit up to 200 keywords and get back the domains appearing in those results, each with a visibility score, avgPosition and medianPosition, an etv traffic estimate, and a keywordsCount. The insight is that your real competitors are whoever occupies your SERPs — often not the brands you'd name from memory. YepAPI serves it at /v1/seo/competitors/serp: post your keywords plus location and language, and receive a ranked competitor list as JSON.
Build your own competitor discovery tool
Build a feature where a user pastes their target keywords and instantly sees their true organic competitor set, ranked by visibility. Use keywordsCount versus visibility to spot domains that rank for many of your terms but at weak positions — competitors you can realistically overtake. The etv estimates let you size each rival's traffic from your shared keyword space. Feed the discovered domains straight into the Keyword Gap API to find the specific terms each competitor beats you on.
SERP competitor API pricing — $0.02 + $0.02 per 100 results
Each analysis is $0.02 per call plus $0.02 per 100 competitor rows returned, so a 100-competitor analysis across your full 200-keyword set costs about $0.04. Competitor-discovery features sit inside $999/mo Ahrefs plans and enterprise Semrush tiers charging $0.15–$0.25 per equivalent call; here you map your competitive landscape for pennies and can re-run it whenever your keyword targets change.
Map your competitive landscape across 200 keywords
Submit your full priority keyword set in one call and read the result as a competitive map: domains with high visibility across many keywords are your core rivals, while those with high keywordsCount but low visibility are vulnerable targets. The medianPosition guards against averages skewed by one strong ranking. Re-running the analysis as you add keywords shows how your competitive set shifts when you expand into new topic areas — keeping your strategy aimed at who actually contests your SERPs.
