invoice_check
PAID ($0.60). Check an invoice in one call: is the VAT right (place of supply, rate, expected amount vs vat_charged), is it overdue and how much statutory late interest is owed, and do seller/buyer tax IDs pass the official format check. Seller countries here: AT, BE, BG, CH, CY, CZ, DE, DK, EE, ES, FI, FR, GB, GR, HR, HU, IE, IS, IT, LT, LU, LV, MT, NL, NO, PL, PT, RO, RS, SE, SI, SK, 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.
