The complete US Social Security Administration dataset: every name by year and gender since 1880, about two million rows, public domain.

What does a name lookup return?

Aggregate counts and rank, the gender split, and with a year parameter the figures for that single year.

Yes. The trend endpoint returns the year-by-year popularity series for a name, optionally for one gender.

Why is a name missing?

The SSA only publishes names with at least five births in a year, so very rare names do not appear.

What does a call cost?

2 tokens. The free plan covers 250 lookups a month.
