Documented steps
GET https://JENKINS_URL/api/json?tree=jobs[name,url,color,jobs[name,url,color,jobs[name,url,color]]] - nest jobs[...] once per folder level to descend.
Folders appear as ordinary entries in the jobs[] array with their own nested jobs[] array; a job inside a folder is addressed at https://JENKINS_URL/job/<folder>/job/<name>/... - the official docs use exactly this pattern (e.g. .../job/Websites/job/jenkins.io/job/master/lastSuccessfulBuild/).
Add one more jobs[...] nesting level for every additional folder depth expected; a job that is not a folder simply has an empty or absent nested jobs array.
color reflects the job's ball-icon status (blue/red/yellow/grey/disabled/aborted/notbuilt, each with an _anime variant while building) - a presentation-layer summary, not the same value space as a build's result field. Docs: https://www.jenkins.io/doc/book/using/remote-access-api/
Known gotchas
Calling /api/json with no tree returns every job's entire exported bean graph recursively - on instances with many jobs this is enormous; always scope with tree.
A tree query only recurses as many jobs[...] levels as are literally written - there is no documented wildcard for unlimited depth, so over-nest if folder depth is unknown.
color is a UI abstraction (different values can map to the same RGB color) - do not parse it as if it were the Result enum used by a build's result field.
Unauthenticated requests to a secured Jenkins receive an immediate 403, not a 401 challenge.
