OTS Service
Per-impression audience reach computed from a monthly traffic spreadsheet.
Problem
DOOH operators report Opportunity-To-See audience reach for every ad impression. Recalculating it by hand for each hour and each facade from raw monthly traffic figures is slow and error-prone.
What we built
Operators upload one spreadsheet a month with daily OTS (day and night) and hourly traffic-share percentages per facade. The service validates it line by line, rejects the whole file on any single error, and recomputes per-output OTS for every hour from a fixed formula, through a self-service console with template download and upload.
Result
Running as a Docker/FastAPI microservice behind Programmatic Engine, replacing the operator team's manual monthly OTS recalculation. A public OTS API (v1, beta) gives partners the same figures per screen and hour.
