Complete Partner Audit Bundle: IBAN + CUI + live ANAF/VIES fiscal status + Risk Assessment + QR Code. Checks IBAN and CUI independently — does NOT confirm the IBAN account is held by the CUI company (see warnings[] in the response).

Currency conversion using current BNR rates, with optional net/VAT/gross RON breakdown

Official BNR daily reference exchange rate table (live fetch + cache, embedded fallback snapshot when offline)

Convert JSON invoice into valid European Standard EN 16931 / CIUS-RO ANAF UBL 2.1 XML e-Factura

Generate a time-sortable UUIDv7-based Idempotency-Key with a deterministic payload hash. Send it as an Idempotency-Key header on a retried call to any paid endpoint: the same key and request returns the cached response with no new charge.

Ultra-fast time-ordered UUIDv7 generator for database primary keys & transactional event logs

Cryptographic SHA-256 hash & HMAC timestamp audit seal for AI agent actions

Generate a SEPA EPC (GiroCode) payment QR code as PNG or SVG from IBAN, beneficiary name, amount and reference. Scannable by European banking apps to prefill a SEPA credit transfer. The IBAN is validated first. $0.002 USDC per call on Base.

RFC 8785 key-sorted JSON canonicalization + SHA-256 hash + Merkle leaf + HMAC-SHA256 audit signature

CUI/CIF Modulo-11 checksum; live ANAF (Romania) or VIES (EU) registry lookup with short timeout, falling back to local format/demo-snapshot data if the live registry is unreachable
