Frequently Asked Questions

Does this work on full names or just first names?

Use first names only. `enrich_name` is case-insensitive and is designed for a single given name, not a full person record.

What kind of signals does it estimate?

It returns an estimated age range, gender with confidence, and nationality probabilities for the name you pass in.

Can I enrich a list of names at once?

Yes. `bulk_enrich` handles up to 10 names per call, which is faster than looping one name at a time.

What does a low probability mean?

It means the model is less certain about the guess. That is especially important for ambiguous names where gender or nationality can vary widely.
