# List developments

`GET /monitoring/v2/developments`

Paginated list of developments with rich filtering. Asset tokens (`assetIds`) may be UUIDs or slugs; unresolved tokens are silently dropped and if none of the supplied tokens resolve, the response is an empty page. Other multi-value filters (`intelCategories`, `intelSubcategories`, `assetSectors`, `assetSubsectors`, `assetEcosystemNetworkIds`) accept comma-separated tokens and apply the same silent-drop semantic — typos return an empty result rather than an error. Use `eventIds` if you need a token to be validated; it returns 400 with the offending token quoted. Results are ordered most recent first. Every development includes a nested `event` reference linking to its parent event.
