POST /v1/supplier-check
Vet a supplier in one paid call: give any of a VAT number, IBAN, domain and LEI and get VAT validity (VIES) + company name, IBAN structure (mod-97 + BBAN), domain status (RDAP), the GLEIF LEI record (legal name, status, parent) and the country — run in parallel, each with a per-field status. summary.allProvidedValid is true only if every provided check confirmed. All checks failing technically → 503, no charge. ?attest=1 → Ed25519-signed.
Start with a quote-only recipe. Payment signing stays in your project.

EVIDENCE
Each record has an exact-route quote outcome. Unresolved templates and potentially mutating methods are labeled instead of being invoked without provider-specific test input. A quote is still separate from a settled paid call.
