Get Hot News and Related Assets

Get hot topic tags, the DeepCoin tradable assets associated with each topic, and deduplicated news in a time window.

Tradable assets are treated as a subset of news tags. Asset tags are excluded from the parent topic ranking. For each news item, the service associates its topic tags with its DeepCoin asset tags by co-occurrence.

This is a public V1 endpoint. Rate limit dimension: IP.

Request URL

GET /deepcoin/market/ai-analysis/hot-news

Request Parameters

Field Name	Required	Type	Description
hours	false	integer	Lookback window in hours. Default: `24`; range: `1` to `72`
tagLimit	false	integer	Maximum number of hot topic tags. Default: `10`; range: `1` to `20`
assetLimit	false	integer	Maximum related assets per topic. Default: `10`; range: `1` to `20`
newsLimit	false	integer	Maximum number of deduplicated news items. Default: `20`; range: `1` to `50`
lang	false	string	News language. Default: `en`. `zh` is normalized to `zh-cn`

Asset associations are based on up to 20 latest news items for each topic and are therefore sample-based. Returned news and association samples are restricted to the requested time window. News and asset counts are deduplicated by news ID.

Response Parameters

Field Name	Type	Description
hours	integer	Applied lookback window in hours
sampled	boolean	Always `true`; asset associations use bounded news samples
partial	boolean	Whether news lookup failed for one or more topic tags
failedTags	array<string>	Topic tags whose news lookup failed
hotTags	array	Hot topic tags ordered by `newsCount` descending
hotTags[].tag	string	Topic tag. DeepCoin asset tags are excluded
hotTags[].newsCount	integer	Topic occurrence count in the requested time window
hotTags[].assets	array	DeepCoin tradable assets found in the topic's sampled news
hotTags[].assets[].asset	string	Canonical asset code
hotTags[].assets[].newsCount	integer	Number of distinct sampled news items associated with the asset
news	array	Deduplicated news within the requested time window, ordered by ID descending

News objects contain id, title, content, source, sentiment, tags, and publishTime, with the same meanings as the asset news endpoint.

When partial is true, successful topics are still returned. Check failedTags before treating the response as a complete ranking.
