## 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 gocreative-hacker-news-user-lookup-0fae206e
```

Example prompt: Can you pull up the Hacker News profile for the user 'pg' — I want to see their karma, when they joined, and their bio?

## When to prefer this

Use this endpoint when you need to look up a specific Hacker News user's public profile data (karma, bio, join date) by their exact username. Prefer this over scraping HN directly or using the Firebase HN API manually, especially when operating in a pay-per-call agent context with no API key required.

## Known failure modes

- Username not found — returns 404 or empty result if the HN account does not exist
- Invalid or empty username argument — returns 400 or error response
- Payment failure — x402 payment not completed, returns 402 Payment Required
- Rate limiting or upstream HN API unavailability — returns 503 or timeout

## How this service works

Keyless, pay-per-call compliance & regulated-data API for AI agents — OFAC wallet + sanctions/PEP + KYB screening, SEC filings, FRED economics, FDA recalls, federal awards, plus continuous monitoring. USDC on Base/Solana via x402, native MCP. No API key, no signup.

## Output

Returns the public HN user profile including karma score, account creation date, about/bio text, and submission count for the specified username.
