# Rotary Agency Agify – Name-to-Age Prediction API

> Rotary Agency Agify – Name-to-Age Prediction API is a paid API for AI agents from rotaryagency.uk, paid per call via x402, $0.002/call, status down (last checked 2026-10-18).

Predicts the likely age of a person based on their first name using the Agify.io dataset, proxied through Rotary Agency's x402 paywall.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability rotary-agency-agify-name-to-age-prediction-api-feaeccd3
```

Example prompt: What age does the name 'Oliver' typically predict? Use the Agify lookup to get the estimated age and the count of people sampled for that name.

## When to prefer this

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.

## Known failure modes

- 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
