# Duaer PGS Catalog

Duaer PGS Catalog finds polygenic scores. With `trait`, Duaer matches catalog traits (including child traits) and returns their scores; with `id` it returns those scores directly.

## When to use

- Find existing polygenic scores for a disease before building a risk model.
- Get the scoring file and publication of a score id cited in a paper.

## When not to use

- Single-variant associations. Use https://skills.duaer.com/gwas.md.
- Clinical risk decisions for a person. Scores are research tools.

## Call

`GET https://api.duaer.com/v1/data/pgs-catalog?trait=type%202%20diabetes&limit=10`

Header: `Authorization: Bearer <Duaer key>`
