What is the Kwinside Search Engine API?
The Kwinside Search Engine API returns the top search engines for a given domain and the full list of search engines Kwinside supports. It has two endpoints under /api/v1/serp/search-engine/*: one returns a domain's top search engines, the other the complete list of supported engines. Data covers six languages and is queried over REST, authenticated with your API key. Pricing is pay-as-you-go at $0.002 per request or a subscription plan, with 20 free requests per day for testing. Use it to discover which search engines to track for a domain, or to check Kwinside's engine coverage before pulling SERP, competitor or best-pages data.
