content_analysis.category_trends

beta 74 credits needs a pack

Monthly mention volume and sentiment of a product or service category since a start date.

GET /v1/content_analysis/category_trends

What you get#

A list of Content Analysis results in Onekey's unified shape, in data (an array). An empty array is a normal, successful answer and is charged like any other; a source that reports "nothing found" as an error returns a free 404 not_found instead.

What it costs#

74 credits for a fresh fetch, charged only when it succeeds.
Free when served from cache (0.2 credit for a cached response over 100 KB).
Free if the request is invalid (never charged) or the source fails or reports not found (refunded).

Parameters#

Name	Type	Required	Default	What it is	Constraints
`category_code`	string	yes	(required)	Numeric category code from content_analysis.categories (10021 = Apparel)	max 10 chars; must match `[0-9]{1,10}`; trimmed
`date_from`	string	yes	(required)	Start of the date range, yyyy-mm-dd (data exists from 2022-10-31)	max 10 chars; must match `20[0-9]{2}-[0-9]{2}-[0-9]{2}`; trimmed

Field mapping#

How this endpoint's source fields become Onekey's unified schema. Fields the source lacks come back as null.

Source path	Onekey field	Transform
`date`	`content.createdAt`	`toIsoDate`
`total_count`	`ext.totalCount`	`toNumber`
`rank`	`ext.rank`	`toNumber`
`sentiment_connotations`	`ext.sentimentConnotations`	-
`connotation_types`	`ext.connotationTypes`	-

Caching and freshness#

Fresh for about 1 hour. Repeat calls in that window are served from cache and are free.
Between 1 hour and 1 day the cached copy is still served instantly and marked stale: true while Onekey refreshes it in the background.
If the source is down when a refresh is needed, the last copy can be served for up to 3 days more (marked stale).
A "not found" is remembered for 2 minutes and is free.
The cache is shared across all customers, which is what keeps repeat calls cheap.

What can go wrong#
