-H "Authorization: Bearer $UNIFAPI_KEY"Parameters
- idpathrequired
- Hacker News username (case-sensitive).
- limitquery
- Hits per page (1–50). Default: 20. Prefer this over `page_size`.
- cursorquery
- Opaque pagination cursor from a previous response's `pagination.next_cursor`. Omit for the first page.
This operation is part of the Hacker News API in the news category. It uses the same Bearer token, request tracing, error model, and billing envelope as every UnifAPI endpoint, so agents can switch between platforms without custom per-vendor glue code.
Use it when a workflow needs Hacker News public data alongside other news and community sources, but should still keep one API key, one account balance, and one predictable JSON contract.
Common agent workflows
- Resolve a public Hacker News identity into structured profile metadata for enrichment agents.
- Refresh creator, company, or account snapshots without managing source-specific response shapes.
- Give an AI agent a stable Hacker News data source without building a per-platform integration.
- Normalize Hacker News responses into the same UnifAPI envelope used across the catalog.
Unified envelope, platform-native fields
- List-style responses return `data` as an array of top-level records plus optional `pagination` for continuation tokens or cursors.
- The operation has a 3 credits ($0.003) minimum charge, so `billing.records_charged` can be higher than the visible records returned.
- If the workspace balance cannot cover every result, the response can be truncated and `billing.truncated_due_to_balance` tells the caller why.
Response status codes
Billing
This operation charges 1 credit per billable record, with a 3 credits ($0.003) operation minimum. Public responses include billing metadata with credits charged, records charged, and remaining workspace balance. Incorrect Credit deductions caused by platform failures can be restored as billing corrections.
Errors and retries
Authentication, validation, rate-limit, not-found, and provider errors use the unified UnifAPI error format. Agents should log `request_id`, retry only retryable failures, and treat invalid API keys, disabled keys, and expired keys as the same public `unauthorized` error type.

Agents & Skills built on Hacker News
You rarely call List a Hacker News user's submissions by hand. These prebuilt agents and skills already read Hacker News data inside Claude or Codex — start from one of them, or call this endpoint yourself.
