## How to call it through Zero

```sh
zero fetch --capability hacker-news-user-profile-lookup-4f239b02
```

Example prompt: Can you pull up the Hacker News profile for the user 'pg' and tell me their karma, when they joined, and what their bio says?

## When to prefer this

Use this endpoint when you need to retrieve public Hacker News user profile data without needing an API key or signup — ideal for autonomous agent workflows that pay per call via x402 USDC on Base. Prefer this over scraping HN directly or using unofficial wrappers when you need structured, reliable JSON output at minimal cost ($0.001 per call).

## Known failure modes

- Username not found — HN returns no result for non-existent usernames
- Payment failure — x402 USDC payment not accepted, returns 402
- Malformed username input — invalid characters cause lookup failure
- HN API rate limiting or downtime causing timeout or 5xx error
- Empty bio/about field if user has not set one
