      description: 'Validates input against the listing''s schema and the caller''s spend cap/seller allowlist, then returns a Lightning invoice to pay (HTTP 402). A verified human account gets one free call on a listing priced at or below the trial cap: it returns HTTP 201 with free_trial true and no invoice — just poll the order. Every other purchase returns an invoice. To redeem a retry token from a failed order, add retry_token: it returns HTTP 201 with free_retry true and no invoice.'
