Get changed Hacker News items and profiles · Hacker News API
Return the IDs of recently changed Hacker News items and user profiles. Useful for incrementally syncing only what changed since the last poll instead of re-fetching everything.
curl https://api.unifapi.com/hacker-news/updates \ -H "Authorization: Bearer $UNIFAPI_KEY"
Parameters
- The parameter for this Hacker News operation. Use the URL-visible slug or id described in the docs.
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 but should still keep one API key, one account balance, and one predictable JSON contract across social, live public-data sources.
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
- Lookup responses return one canonical object in `data` with stable identifiers, source URLs where available, and platform-specific metadata normalized into predictable JSON.
- This operation has a zero-credit multiplier, so successful responses include zero-charge billing metadata.
- A not-found or invalid-input condition uses the unified UnifAPI error shape, so callers do not need special handling for each source platform.
Response status codes
Billing
This operation is free: it has a zero-credit multiplier and still returns billing metadata with zero credits charged.
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.
Fields in the data object
A successful Get changed Hacker News items and profiles call returns one data object with these fields.
- itemsinteger[]
- profilesstring[]
