Name Intelligence API
Turn a first name into structured intelligence: gender with a real probability, all-time popularity, active years, peak year and per-decade history — built from 146 years of official US Social Security records (1880-2025, 105,966 distinct names) plus the Census Bureau's 162,253-surname frequency file. One call answers what gender-inference services charge monthly for: Michael -> male at 99.5% over 4.4M records; ambiguous names answer honestly (Taylor -> female at 74%); unknown strings return null instead of a guess. Batch up to 100 names per POST for CRM and list enrichment. Search names by prefix, gender or popularity; pull full statistics with decade-by-decade counts (watch Ada peak in 1918 and revive in the 2020s); look up any surname's rank, count and per-100k frequency (Smith #1, Nguyen #38). All source data is public domain and refreshes with the SSA's annual May release. Built for CRM enrichment, personalization, analytics, form autofill and demographic research — statistical inference from official records, not identity claims about individuals. Complements our Baby Names API (popularity browsing) with the data-enrichment side. Self-hosted — no third-party calls at request time.
