Example prompt: What are the OSV advisory fixed-version boundaries for starlette 0.27.0? I want to know which versions patch any known vulnerabilities for that release.

## When to prefer this

Use this endpoint when you specifically need OSV-sourced advisory fixed-version boundary data for the starlette PyPI package. Prefer this over general vulnerability scanners when you want structured, machine-readable fix-version ranges scoped precisely to starlette, or when integrating OSV advisory data into automated dependency auditing pipelines.

## Known failure modes

- Invalid or unrecognized package version returns an error or empty advisory list
- Network or upstream OSV data unavailability causes a timeout or 5xx response
- Malformed page_token leads to pagination errors
- Specifying a version that predates OSV coverage may return no results
- Rate limiting or payment failures (x402) block the request
