Report placements bought anywhere

Open to all; rate limited per address (5,000 rows/hour). Send your API key to be counted as a distinct buyer; anonymous reports are stored but count as one buyer per sending address. Feeds demand and niche taste, read only in aggregate behind a three-buyer floor. Anchor text is never stored, only its type; a buyer_ref that looks like an email is hashed; duplicates within 30 days are one observation. Nothing sent here is returned to another caller.
