The raw transaction record of your programmatic activity. Every bid request, every response, every impression, every click, timestamped and stored. Log-level data is what makes independent verification possible. Without it, you are trusting the platform's reporting. With it, you can audit the auction, reconstruct the supply path, and find the discrepancies between what was served and what was billed. Platforms that do not provide log-level access do not want you looking that closely.
