PAID ($0.40). Is this invoice overdue, by how many days, and how much statutory late-payment interest is owed (Actual/365 simple, rate and workings cited). Late-payment regime: AT, BE, BG, CY, DE, DK, EE, ES, FI, FR, GB, GR, HR, IE, IT, LT, LU, LV, MT, NL, PL, PT, SE, SI, SK; statutory interest only: CH, CZ, HU, IS, NO, RO, RS, TR. Send due_date, or invoice_date with terms_days. Anything we cannot answer in full is refused free (coverage_gap, no_charge). Shares the 3 free calls per IP per day with the answer tools. Pass api_key if you have one (card checkout at /pricing); otherwise the result is the x402 payment requirement. Optional receipt (boolean, default false): on a paid success, include an Ed25519 answer receipt at no extra USDC. An answer receipt is not a series certified extract (GET /v1/certified/{country}/{series} is $0.10 and is not an MCP tool) and is not legal advice. Verify with verify_answer_receipt against /certified/public-key.
