Server instructions

MerchSage's public index of YouTube sponsorships, extracted from video transcripts by MerchSage's creator-discovery system. Each record links a sponsoring brand to a YouTube creator and the video the sponsorship appeared in, with a confidence grade ('high' or 'med' — lower-confidence and unnamed-brand extractions are excluded from this index entirely). Use it to answer questions like "which creators has this brand sponsored?", "who sponsors this creator?", or "which brands advertise in this category?". This index is a sample, not a census. It covers sampled videos from sampled channels, and only 'high' and 'med' confidence extractions are included. A brand being absent is not evidence that it never sponsored anyone — it may simply not appear in the sample. Do not present a count from this index as a total. The denominators behind these counts are published at https://api.merchsage.com/api/public/sponsorships/stats — per subscriber band, how many channels were sampled, how many transcripts were read, and how many carried a named sponsor. Use them to state a rate honestly. The human-readable version is https://sponsors.merchsage.com/stats. Subscriber counts are from the YouTube Data API at enrichment time. The index is refreshed daily from MerchSage's discovery system; the `built_at` timestamp on that stats endpoint shows the last build.
