How this service works
Free-source data APIs (100% margin, no proxy, $0.002/call): ...
Output
Returns a JSON object containing the input name, a predicted age (integer), and a count representing the number of data points the prediction is based on. Example: {"name": "John", "age": 53, "count": 12345}.
Example use cases
Demographic profiling by name
“I have a list of customer first names and I want to know the predicted age for each — start with the name 'Margaret' and tell me what age Agify estimates and how many people that prediction is based on.”
Marketing segmentation by name age
“We're targeting our campaign at people likely to be over 40 — can you look up the predicted age for the name 'Barbara' to see if it fits our target demographic?”
Data enrichment for user records
“I'm building a user profile for someone named 'Liam' and I'd like to enrich it with the statistically predicted age for that name — what does the Agify API return for it?”
Technical details
Endpoint
GEThttps://rotaryagency.uk/api/free/agify?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, statistically-based age estimate from a first name alone and do not have other demographic signals available. It is ideal for lightweight data enrichment, demographic segmentation, or curiosity-driven lookups. Prefer this over building your own model when a simple probabilistic estimate is sufficient. Note that it proxies Agify.io, so if you have a direct Agify.io API key, that may be cheaper at scale.
Side effects
- Missing or empty name parameter returns an error or null age
- Obscure or very rare names may return a null age due to insufficient data
- Payment failure via x402 prevents the call from completing
- Rate limiting if quota is exceeded
- Non-alphabetic or numeric name strings may return unexpected results
