# Weibo API: keyword search, posts, comments and trends

Use the Weibo data API for public topic discovery and content retrieval. Search, post, comment, profile, user-post and trending capabilities are listed separately so you can choose the smallest set of calls needed for a research question.

## Start from a question and a search mode

Search parameters can select different result types or ordering. Use only values shown in the reference; omitting an optional parameter is different from sending a guessed value. Select relevant posts before fetching their comment threads.

## Treat trends as a time-specific snapshot

Capture the retrieval time with a trending response. A trending list is not a measurement of all platform activity and does not establish population sentiment. Compare like-for-like snapshots if you build your own trend history.

## Separate post IDs from author IDs

Post detail and comment endpoints identify a post; profile and user-post endpoints identify an account. Retain original identifiers and source URLs. Do not convert long IDs through a JavaScript floating-point number.

## Respond to errors without a retry storm

A 400 means the request or resource needs review, not necessarily an authentication problem. A 429 requires backing off. Empty or failed retrievals are not successful-call charges. Keep retries bounded and show a partial-data state to your users.
