One-section preview of the full Prop 65 / FTC / EPR Compliance Ops Pack (/v1/compliance-pack, $0.12, all 3 domains). Returns one domain as JSON: buyer, triggers, intake fields, ops checklist, do-nots. Pass ?domain=prop65|ftc-rosca-cancel|packaging-epr. Ops checklist only. Not legal advice. Not a compliance certification. An unknown domain 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.
