SimilarSites
SimilarSites. Response follows the SimilarWeb v5 envelope (meta + data). Date window (upstream SimilarWeb constraint): start_date and end_date must span EXACTLY 3 consecutive months — a 1- or 2-month span is rejected with upstream error 120 ('must span exactly 3 month(s)'). That span must also be SimilarWeb's most recent supported window, which advances forward each month; an older or out-of-range span is rejected with error 101 ('Dates not in range'). In practice, request the three most recent completed months (e.g. if the latest published month is 2026-07, use start_date=2026-05 and end_date=2026-07). To read the exact currently-supported range, call SimilarWeb's /describe endpoint for this API.
