Continuous Fair Offer certification for an x402 API: the full certification now, then re-run about once a day for 30 days. The public status and badge show the latest check, so a pass is withdrawn the day a check fails, and every check's signed result is published. One payment, no renewal; a seller pays for the checking, never for the outcome.
