# Factori, free: People enrichment API

> Fetch detailed or tailored People data using a unique ID or filter-based enrichment

Factori's people enrichment API on its Free plan. It costs $0.00 per 1,000 people. It returns 4 of the 13 key fields we check: Experience, Education, Skills, Location.
We ran Factori in [our people enrichment API benchmark](https://datacircle.dev/best-people-enrichment-api.txt). We didn't score any Factori plan.
This plan is free. We rank 191 plans for people enrichment APIs by price. Half the plans cost $10.00 per 1,000 people or less.
[Coldlytics's $49 monthly plan](https://datacircle.dev/person-enrichment-apis/coldlytics/49-monthly/llms.txt) is the cheapest paid plan per 1,000 people: as little as $0.0095. Coldlytics's $49 monthly plan covers up to 5,184,000 people a month at no extra cost.
[GetProspect's $49 monthly plan (/v2/people/{id})](https://datacircle.dev/person-enrichment-apis/getprospect/49-monthly-starter-get-v2-people-id/llms.txt) covers any number of people. GetProspect's $49 monthly plan costs as much up front as Coldlytics's $49 monthly plan.
