## 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 peptidesdirect-catalogue-feed-cb0613e3
```

Example prompt: Pull the full PeptidesDirect catalogue feed so I can see every peptide product with its current stock levels, EUR prices, available variants, and lab reports.

## When to prefer this

Use this endpoint when you need a comprehensive, up-to-date snapshot of all peptide products from PeptidesDirect in a single call, including variant-level detail, live EUR pricing, stock availability, and lab documentation. Prefer this over scraping the website or checking products individually when you need bulk catalogue data for comparison, inventory monitoring, or sourcing decisions.

## Known failure modes

- API returns 402 Payment Required if x402 payment is not provided or fails
- Empty or partial catalogue if feed is temporarily unavailable
- Stale stock data if the feed hasn't been refreshed recently
- Network timeout for large catalogue responses
- 401/403 if payment credentials are invalid
