Try it

This sends a real call to https://api.okdata.online and is billed as usual: at most $0.006. Failed calls are free. Your key goes only to that address and is never stored on this site.

Known limits

About 20 posts come back per page; the platform sets the page size, so there is no page-size parameter.
For the next page, pass page.next_cursor back as cursor. A cursor stays valid for 24 hours. When page.has_more is false there is nothing left.
1 fields of Post this endpoint cannot give

Returned fields

data.items is a list of Post.

Field	Type	View	Description
`id`	string	compact	Post ID on the platform.
`url`	string	compact	Link to the post.
`type`	string	compact	What kind of post it is.
`title`	string \| null	compact	Title, where the platform has one (videos, notes, articles).
`text`	string	compact	Caption, body or description as plain text; articles come as Markdown.Long text: view=compact may shorten it.
`lang`	string \| null	standard	Language code, as reported or detected.

Show all 12 fieldsHide the other 6

Field	Type	View	Description
`published_at`	string \| null	compact	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	compact	Who posted it.
`metrics`	Metrics	compact	Counts at fetch time; a count the platform hides is null.
`images`	string[] \| null	standard	Image URLs for image posts and notes.
`hashtags`	string[] \| null	standard	Hashtags or topics, without the # sign.
`ext`	object	full	Platform-specific extras. Only returned with view=full.

The view column is the smallest view a field comes back in: compact returns only compact fields, standard adds the standard ones, full returns everything. The default is standard.

What this endpoint cannot give

These fields of Post come back as null here, and meta.unavailable names each one with its reason.

Common errors

Every error has the same shape and says whether it was charged. The ones this endpoint can return:

HTTP	Code	Meaning	Charged
400	`invalid_params`	A parameter is missing, has the wrong type or value, or the method is wrong. problems lists each one; param names the first.Retry: after a fix	no
400	`cursor_mismatch`	The cursor was sent to another endpoint, or with other parameters than the page it came from (view and fields may change).Retry: after a fix	no
401	`unauthorized`	The key is missing, malformed, revoked, disabled or expired (reason says which when known).Retry: no	no
402	`insufficient_balance`	The balance (available) cannot cover the most this call could cost (required).Retry: after a fix	no
404	`not_found`	The post, account or page does not exist or is not public. Endpoints whose charge_when_not_found is above 0 charge this answer (the source billed us for it): the body then says charged: true and amount.Retry: no	no
410	`cursor_expired`	The cursor is older than the endpoint's cursor lifetime (page.cursor_expires_at said when).Retry: no	no
429	`rate_limited`	The account sent too many requests this minute (reason: rate) or has too many calls running (reason: concurrency).Retry: yes	no

502	`upstream_failed`	Every data source for this endpoint failed on this request.Retry: yes	no

Questions

How much does the X account mentions API cost?

You pay $0.0003 for each of the posts a call returns, at least one and at most $0.006 per call (20 posts). 1,000 posts cost $0.30. An empty page is billed as one item; failed calls are not charged.

How do I get the next page?

Pass page.next_cursor from the response back as the cursor parameter. When page.has_more is false there is nothing left. Every page is its own call at $0.0003.

Do I need a X (Twitter) account, cookies or a QR login?

No. You send only your okdata API key. The data is public data from X (Twitter); nothing is fetched with your own X (Twitter) account.

Am I charged when a call fails?

No. Every error response says charged: false, except a timeout, which says charged: null until the outcome is known. Resend with the same Idempotency-Key and you are never charged twice.

What if X (Twitter) does not show a field?

The field is null, and meta.unavailable names it with the reason: platform (the platform never shows it) or capability (we cannot fetch it yet).
