How this service works

Hacker News user profile. Returns karma score, account age, about text, and number of submissions.

Example use cases

Example prompt

Technical details

Endpoint

GEThttps://hackernews-x402.vercel.app/hn/user

When to prefer

Use this endpoint when you need structured profile data for a specific Hacker News user — karma, tenure, bio, and submission count — as a single low-cost lookup. Prefer this over scraping HN directly or using the Firebase HN API when you want a simple, paid, structured JSON response without managing API credentials.

Side effects

Username not found — returns error if the Hacker News username does not exist
Missing required 'username' query parameter — returns a 400-style error
Network or upstream Hacker News API unavailability — may return 5xx or timeout
Payment failure — x402 payment of $0.002 USDC not processed, returns 402
