How this service works
Takes a podcast episode of up to 120 minutes and returns its advertising segments: paid sponsor reads, self-promotion (newsletter, Patreon, merchandise) and cross-promotion of other shows, each with start and end on sentence boundaries, the advertiser and any discount code as spoken, and a verbatim evidence phrase that is checked against the transcript — a segment without verified evidence is reported but never cut. Product mentions in the conversation itself are not counted as ads.
Output
Returns a list of detected advertising segments, each containing: start and end times on sentence boundaries, the ad kind (sponsor, self_promo, or cross_promo), the advertiser or promoted entity, any discount code spoken verbatim, and a verified evidence phrase from the transcript. Segments without verified transcript evidence are reported but not cut. If remove_ads is enabled, also returns a cleaned audio file in the requested format (opus or mp3) encoded as base64.
Example use cases
Sponsor audit for podcast analytics
“I need to audit this 90-minute podcast episode to find every paid sponsor segment — give me the start and end times, the advertiser name, and any promo codes they mentioned. The file is at https://mypodcast.com/ep100.mp3, and it runs 90 minutes.”
Ad-free episode export for paying subscribers
“Take this 60-minute podcast episode from https://feed.example.com/ep77.mp3 and return a clean version with just the paid sponsor ads cut out, as an MP3 — it's 60 minutes long.”
Cross-promotion map for podcast network
“I want to know every time another show is cross-promoted in this 30-minute episode at https://network.example.com/show5ep3.mp3 — list each cross-promo segment with timestamps and the exact phrase used, 30 minutes duration.”

Endpoint
POSThttps://medien.halowerk.com/v1/ad-detect?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically identify, timestamp, and optionally remove advertising segments from podcast episodes up to 120 minutes long, with transcript-verified evidence for each detected segment. It is uniquely suited for podcast analytics pipelines, ad-free subscriber exports, and sponsor auditing workflows. Prefer it over generic audio transcription when the goal is specifically ad detection with structured metadata (advertiser, discount code, ad kind) rather than full transcription.
