## 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 open5e-d-d-5e-feat-search-bff16c9d -d '<json body>'

## When to prefer this

Use this endpoint when you need structured, rules-accurate D&D 5e feat data including prerequisites and effects from the Open5e dataset. Prefer this over generic web search when you need machine-readable JSON feat data for character builders, rule lookups, or 5e tools.

## Known failure modes
