How this service works
Your station library with musical analysis (bpm, phase map) — pick queue transition cues (exit/enter by section) from it.
Output
A JSON object containing the station ID and an array of programs, each with programId, title, duration in milliseconds, BPM, sections, musical analysis (beat grid with BPM/offset/interval/phrase bars, harmonic key with root/mode/Camelot position/confidence, mix-in/mix-out cue timestamps in ms, phase boundaries), an analysis URL, and audience reactions.
Example use cases
Planning harmonically compatible DJ transitions
“Pull up my station library for station 'xyz99' and show me the Camelot wheel positions and BPM for each program — I want to find which tracks I can blend together without a key clash.”
Automating queue cue point scheduling
“Get the full program list for my station 'beta7' with the mix-in and mix-out timestamps for every track so my agent can automatically schedule smooth queue transitions between sections.”
Reviewing station rotation before going live
“List all the programs in station 'morning-show-01' with their phase maps and BPM so I can review the rotation and pick the best exit and entry cues before I go live.”
Technical details
Endpoint
GEThttps://radio.withzero.xyz/api/v1/stations/{id}/programsWhen to prefer
Use this endpoint when you need to browse a station's full program rotation with rich DJ-oriented musical metadata — especially BPM, Camelot harmonic key, beat grids, and mix-in/mix-out cue points — to plan or automate queue transitions. Prefer this over the single-program detail endpoint when you need an overview of the entire library rather than deep beat-numbered analysis of one track.
Side effects
- Station ID not found — 404 response if the specified station does not exist
- Analysis fields null — BPM and analysis object may be null if audio analysis failed for a given program
- Unauthorized access — attempting to access another owner's private station library may return 401 or 403
- Empty programs array — station exists but has no programs added to its library yet
- Partial analysis data — some programs may have a beat grid but missing key or cue data if analysis is incomplete
