## 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 koa-advisory-fixed-version-boundaries-osv-npm-9e43a634 -d '<json body>'
```

Example prompt: Check what OSV advisory fixed-version boundaries exist for koa version 2.13.0 — I want to know what patched versions I should upgrade to.

## When to prefer this

Use this endpoint when you specifically need OSV advisory fixed-version boundary data for the npm package 'koa'. It is scoped exclusively to koa, making it more targeted than a general OSV query tool. Prefer it over generic vulnerability APIs when you need structured, versioned fix-boundary information for koa in automated dependency auditing or upgrade pipelines.

## Known failure modes

- Unknown or invalid version string returns no advisory data or an error
- Specifying 'latest' when the registry is unreachable may fail to resolve
- Non-koa package names ignored — endpoint is scoped only to koa
- Network timeout if OSV upstream is slow
- page_token invalid or expired may cause pagination errors
