Search the ISO 20022 catalogue by use-case, message type or keyword (e.g. 'reconciliation', 'make a payment', 'pacs.008') and get the matching message types, their family, and which package provides them.

List every ISO 20022 family the gateway routes to (pain, pacs, camt, acmt): its capabilities, backing package, and whether that package is installed in this environment.

List the whole ISO 20022 suite the gateway knows: the message families (pain/pacs/camt/acmt), the Exceptions & Investigations messages (camt.056/camt.029), and the specialized servers (reconciliation, agent-payment bridge) with what each does.

Describe a message type: its required fields and input JSON Schema, resolved from the family's backing server.

Validate records for a message type against its JSON Schema, via the family's backing server.

Generate a validated ISO 20022 XML message from records; the XML document is returned in the 'xml' key. Supported for initiation and interbank families (pain, pacs, acmt); statement families (camt) are inbound-only and return an explanatory error. On failure the 'error' value lists every missing or invalid field at once — fix them all and retry once.

Parse an inbound ISO 20022 XML message into structured data. Parse coverage is per-family: pacs (e.g. pacs.008) and camt (e.g. camt.053) only. The initiation families pain and acmt are outbound-only — they have NO parser here, so do not attempt a generate→parse round-trip for pain.001 or acmt.001; use 'validate' or the backing server's XSD validation instead.
