## 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 package-deprecation-research-for-integration-developers-a652920a -d '<json body>'
```

Example prompt: Can you look up whether the 'request' npm package is officially deprecated and what the recommended successor or migration path is? Search up to 5 results focused on integration developers.

## When to prefer this

Use this endpoint when you need to quickly determine whether a specific software package or library has been officially deprecated and what developers should migrate to, especially in integration engineering contexts. Prefer this over a generic web search when you want results filtered to deprecation and successor migration topics rather than general documentation or tutorials.

## Known failure modes

- No deprecation notice found if package is still active or too niche
- Outdated or inaccurate web results if the package is obscure
- Query too broad returns irrelevant results unrelated to the target package
- Max results limit of 10 may not surface all relevant notices for popular packages
- Payment failure via x402 protocol if USDC funds are insufficient
