FAQ
Questions Genderize owners ask.
- 01
Is an API Key required for Genderize.io?
No, you can use the service for free without an API key for up to 100 requests per day. For higher volume, you can obtain a key from genderize.io.
- 02
How accurate is the gender prediction?
The API returns a 'probability' score between 0.0 and 1.0. A score of 0.99 means the API is 99% certain of the associated gender based on its database.
- 03
Can I localise the results for a specific country?
Yes! Use the 'countryId' parameter with an ISO 3166-1 alpha-2 code (e.g., 'BR' for Brazil) to get results optimized for that specific region.
- 04
How many names can I check at once?
The 'estimate_genders_bulk' capability allows you to check up to 10 names in a single API request, which is efficient for processing small lists.
