FreeWord Intelligence API

Get word endings

GET/words/{word}/endingsNo key

A word's endings as the nightly update holds them: counts, the key endings and open names per ending.

Reads the WordEndings row. A word with no count (not scanned, or not counted yet) answers byGroup and openByEnding null; zeros are real. The cheapest ending is a keyed include only: a name chosen by price never reaches the free tier.

AccessNo key. Limited per address; a key adds the paid fields.

BillingOne call.
