How this service works

Hacker News user profile: karma, account creation date and age, about text (HTML stripped), number of submissions and the 10 most recent submission ids.

Output

Returns a JSON object with the user's HN username, karma score, account creation timestamp, account age in days, HTML-stripped about/bio text, total submission count, their profile URL on news.ycombinator.com, and an array of up to 10 most recent submission IDs.

Example use cases

Vetting a Hacker News commenter

“Before I respond to this HN comment, can you look up the user 'dang' on Hacker News and tell me their karma, how long their account has been around, and what their bio says?”

Researching a potential hire's HN presence

“I'm interviewing a candidate who listed Hacker News activity on their resume — can you fetch the HN profile for username 'patio11' and tell me their karma, account age, and recent submissions?”

Tracking a founder's HN engagement

“I want to understand how established the founder behind username 'sama' is on Hacker News — can you get their karma score, when they joined, and how many things they've submitted?”

Technical details

Endpoint

GEThttps://hn.genexxis.com/user?utm_source=zero.xyz

When to prefer

Use this endpoint when you need structured profile data about a specific Hacker News user — karma, account age, bio, and recent submission IDs — without scraping the HN website directly. Prefer this over the sibling story/search endpoints when the goal is user reputation analysis, account vetting, or enriching data with HN community standing. It is fast, cheap at $0.003 per call, and returns clean pre-parsed data including HTML-stripped bio text and computed account age in days.

Side effects

Username not found — HN username is case-sensitive, wrong case returns an error or empty result
User has no submissions — submitted count is 0 and recent submission IDs list is empty
User has a private or minimal profile — about text may be empty string
Payment failure — x402 payment of $0.003 USDC not processed, request rejected
Rate limiting — too many requests in a short period may result in throttling
