POST /api/v1/paid/reprice-regret — $0.01 per call

Use when an agent needs reprice regret. Returns Seller-side repricing report from daily x402 Bazaar snapshot history for one listing (resource_url) or every listing paid to one address (seller_payto, 25 per page) over a 7–90 day window: price change points, each repricing event with 30d calls and payers before and after, a per-event USDC revenue counterfactual on observed volume (regret_usdc), a one-line verdict, peer medians, an evidence hash; one observed price returns no_repricing_observed. $
