```sh
zero fetch --capability rotary-agency-osv-data-api-02d00bc7
```

Example prompt: Can you look up the open source vulnerability record for the lodash npm package and tell me which versions are affected and what the severity is?

## When to prefer this

Choose this endpoint when you need lightweight, pay-per-call OSV vulnerability lookups without subscription overhead. At $0.002/call it is cost-effective for low-volume security checks inside agent workflows. Prefer it over self-hosted OSV tooling when you need a simple REST lookup without infrastructure management.

## Known failure modes
