About the Similarweb API

The AnyAPI Similarweb API returns Similarweb data as normalized JSON across 2 endpoints: overview and similar sites. You call one endpoint per job with a single key, and AnyAPI routes each request across 2 sources, falling back automatically when one fails. Pricing is in US dollars, from $1.67 per 1,000 requests on the cheapest endpoint, with no subscription and no monthly minimum. Over the last 30 days, 100.0% of Similarweb calls through AnyAPI succeeded, with a request-weighted median response time of 4.4 seconds across 3 measured calls.
