iSpot REST API v4
REST API for accessing iSpot.tv TV and video ad measurement data — airing occurrence, estimated spend, household and person-level impressions, attention metrics, OTT/streaming impressions, TV conversion attribution and lift, plus the reference entities behind them (spots, creatives, brands, industries, networks, shows, episodes, products). OAuth 2.0 client credentials; JSON responses with a data + meta envelope, bracketed filter[]/page[] parameters and comma-separated include expansion; errors are RFC 9457 application/problem+json. Per-endpoint rate limits are published. The full endpoint reference and the interactive API demo are gated behind a developer-site account, but the conventions, filters, rate limits, changelog and Python samples are public.
