4 endpoints on 4 platforms return trending posts as the same Post object. The posts a platform ranks as popular or trending right now, hottest first, each with its text, author and counts. A call costs from $0.002 to $0.04, each endpoint at its own price; a failed call is free.

## The object it returns: [Post](https://okdata.online/docs/objects/post/)

Every endpoint above returns these fields with the same names and types. A field a platform does not show comes back null and is named in meta.unavailable.

| Field | Type | Meaning |
|---|---|---|
| `id` | `string` | Post ID on the platform. |
| `url` | `string` | Link to the post. |
| `type` | `string` | What kind of post it is. |
| `title` | `string \| null` | Title, where the platform has one (videos, notes, articles). |
| `text` | `string` | Caption, body or description as plain text; articles come as Markdown. |
| `lang` | `string \| null` | Language code, as reported or detected. |
| `published_at` | `string \| null` | When it was published, ISO 8601 in UTC; null only where the source gives no time (wechat_mp.articles.metrics, wechat_channels.videos.metrics, youtube.channels.videos.list with type=short), then listed in meta.unavailable. |
| `author` | `AccountRef` | Who posted it. |
| `metrics` | `Metrics` | Counts at fetch time; a count the platform hides is null. |
| `images` | `string[] \| null` | Image URLs for image posts and notes. |
| `hashtags` | `string[] \| null` | Hashtags or topics, without the # sign. |
| `ext` | `object` | Platform-specific extras. Only returned with view=full. |

## The same call on two platforms

Same parameters, same paging, same response shape. Only the path changes.

## What people use it for

- See which posts are taking off today, not only which topics.
- Save the feed every hour and study what kind of post reaches it.
- Give an AI agent today’s popular posts before it suggests ideas.

## Questions

### How is this different from a trending topics board?

A trending board lists topics or search terms with a rank. This returns the posts themselves, with their text and counts, so you read what is popular instead of guessing from a keyword.

### Can I get yesterday’s feed?

No. Each call returns the board as it stands now, even where the board itself covers the last few days. To keep a history, call on a schedule and store each result with the time you read it.

### Which platforms have it?

Only platforms that publish a public popular feed can offer it, and endpoints are added one platform at a time. The table above lists the ones you can call now.
