## 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 starlette-advisory-severity-breakdown-osv-pypi-70573ce9 -d '<json body>'
```

Example prompt: What's the vulnerability severity breakdown for starlette version 0.37.2 from OSV? I want to know how many critical, high, medium, and low advisories exist for that exact release.

## When to prefer this

Use this endpoint when you specifically need OSV-sourced advisory severity data for the starlette Python package and want a pre-scoped, per-package breakdown without querying a general vulnerability database yourself. Prefer this over generic CVE APIs when you only care about starlette and want a fast, low-cost lookup with severity bucketing already done.

## Known failure modes

- Unknown or misspelled package version returns empty or error response
- 'latest' version resolution may lag behind actual PyPI registry if OSV data is stale
- No advisories found may mean genuinely clean package or incomplete OSV data
- Rate limiting or payment failure may block access
- Pagination token mismatch may cause incomplete results
