Fields

Field	Type	Notes
`items`	array	Trending public X topics or search words.
`items[].trendId`	string	Sourcevine id for the trend row.
`items[].name`	string	Trend label as the platform publishes it.
`items[].rank`	integer \| null	Trend position when reported.
`items[].postCount`	integer \| null	Public volume when reported.
`nextCursor`	string \| null	Pass as cursor to request the next page.
`fetchedAt`	ISO datetime	When Sourcevine read the public page.
`sourceTimestamp`	ISO datetime \| null	The platform timestamp when it is available.
`cached`	boolean	True when this answer repeats an identical request made moments earlier.
`cacheAgeSeconds`	integer	Seconds since the reading was taken.

Availability States

Status	Charged	Client behavior
`available`	yes for live reads	Use data.
`not_found`	yes	Store the state and stop polling.
`private`	yes	Store the state and stop polling.
`unsupported`	no	Fix the URL or call the matching API.
`upstream_unavailable`	no	Retry later with backoff.

Unavailable resources return `success: true`, `available: false`, `availability`, and `data: null`. API or authentication failures return `success: false` with an `error` object.

Billing

A call costs 1 credit. A deleted, private or empty resource is charged like any lookup and says so. An unsupported URL or a read we could not complete is not charged. The `X-Credits-Charged` response header is the source of truth for what happened on that request.

Successful responses include `fetchedAt`, the time we read the platform.

What This API Does Not Return

No contact or bio fields: Bios, email addresses, phone numbers, postal addresses and messenger handles are outside the response contract.
No private data: Private accounts, restricted content and unavailable resources return typed availability instead of guessed data.
No prediction: Trend APIs return what the platform publishes now. They do not forecast future rank, reach or revenue.
