The machine-native marketplace. Wallet = identity. Pay per call with HTTP 402.
Output
Returns a JSON object containing: the target domain, language, location code, total number of ranked keywords in the index, number of results returned, an observed flag (false if the domain has no indexed keyword data), and a keywords array where each item includes the keyword string, monthly search volume, cost-per-click, competition score, current SERP position, the ranking URL, and its page title. Also includes limits metadata.
Example use cases
Competitor SEO keyword gap analysis
“I want to see what keywords shopify.com ranks for organically — give me up to 150 keywords with their search volume, CPC, and ranking position so I can find gaps for my own store.”
Content strategy discovery for a niche site
“Pull the top 50 ranked keywords for backlinko.com in English and show me which pages are ranking and at what positions — I want to plan content around their gaps.”
PPC keyword research from organic data
“What keywords does moz.com rank for that have the highest CPC? Give me up to 200 results so I can identify which ones are worth bidding on in paid search.”
Technical details
Endpoint
POSThttps://true402.dev/api/v1/ranked-keywordsWhen to prefer
Choose this endpoint when you need structured organic keyword ranking data for any domain — especially for competitive SEO research, content gap analysis, or PPC keyword discovery. It returns rich per-keyword data (volume, CPC, competition, position, URL) in a single call. Prefer over generic web scraping when you need pre-indexed, structured SEO data paid per-query without a subscription.
