One-section preview of the full Niche Ops Briefs Pack (/v1/niches, $0.08, all 11 briefs). Returns one service niche brief as JSON: title, buyer, first-dollar motion, as_of date. Pass ?slug=, e.g. ?slug=shopify-gmc-feed-ops. Ops notes only; no market-size claims. An unknown slug returns 404 and is not charged. How to buy: GET the endpoint; it answers HTTP 402 with the exact USDC amount and payTo on Base, then retry with the x402 payment (settles through the Coinbase CDP facilitator). Price is per call.
