The first 8 rows of a response recorded 2026-10-12 19:05 UTC.

## Parameters

| Parameter | Type | required | Description |
| --- | --- | --- | --- |
| `username` | text | Yes | X handle, without the @. Example: `NASA`. |
| `cursor` | text |  | Cursor returned by the previous page. Pass `page.next_cursor` of the page before, unchanged. Each page is charged as a call of its own. |
| `view` | text |  | How much of each item to return. All three cost the same. Values: `compact`, `standard` (default), `full`. |
| `fields` | list of text |  | Return only these fields. Each by its path, such as `author.name`. |

## Returned fields

`data.items` is a list of post objects. Stable: fields are only ever added.

Three views: `compact` (the most used fields, long text cut short), `standard` (the default: every standard field) and `full` (adds `ext`, the platform's own fields). A field is in the view named and in every larger one.

| `title` | text | Title. | `compact` | The platform has none |
| `text` | text | Body text. Long text: the compact view keeps the first 500 characters and says so in `warnings`. | `compact` | Yes |

| `post_id` | text | ID of the thread's root post when this is a reply; otherwise null. | `compact` | Yes |
| `parent_id` | text | ID of the item it replies to directly; otherwise null. | `compact` | Yes |
| `root_id` | text | ID of the first-level reply its thread hangs under. | `compact` | The platform has none |
| `ext.quotes` | integer | Times it was quoted. | `full` | Yes |
| `approximate` | list of object | Which numbers of this item are approximate or lower bounds; absent when all are exact. | `compact` | Yes |
| `approximate[].field` | text | Path of the field, such as metrics.views. | `compact` | Yes |
| `approximate[].kind` | text | Approximate, or a lower bound. Values: `approximate`, `lower_bound`. | `compact` | Yes |

A field with no value on an item is `null`. A field this endpoint cannot give is left out and listed in `meta.unavailable`.

Typical size of one item: `compact` 581 B, `standard` 1.2 KB, `full` 1.2 KB (measured on the response recorded 2026-10-12 19:05 UTC).

## Paging

20 items a page. The page size is the platform's; `limit` is not accepted.

For the next page pass `page.next_cursor` as `cursor`; a cursor is valid for 1 hour. `page.has_more` is false on the last page.

## When you are charged

| Case | Charged |
| --- | --- |
| A result with data | $0.0003 for each valid item returned, at least $0.0003 a call |
| Each further page | charged as a call of its own |
| An empty result | $0.0003 |
| Invalid parameters, a failure of ours or of the data source, a timeout | not charged |
| The most one call can cost | $0.0060 (send `X-Max-Price` to refuse anything above your own limit) |

Prices as read 2026-10-21 10:10 UTC, under price book 2, in effect since 2026-10-17 11:00 UTC; the Playground reads the price in force before a run.

## If the object does not exist

An account that does not exist cannot be told from an account nobody mentions: both return an empty result, not a 404, and are charged as an empty result is.

## Errors

Every error has the same structure: `code`, `message`, `charged`, `retry`, `retry_after_seconds`, `param`, `docs_url`.

## Use it in your AI

`dataxapi setup` gives the agents on your machine (Claude Code, Codex, Cursor) the DataXAPI MCP server and the base skill. The key is read from DATAXAPI_API_KEY; none is written into a file.

MCP server: `https://api.dataxapi.com/mcp`. The entry for your client is under MCP in the request examples of this page; then ask your agent to call `x.users.mentions.list`.
