Cite payments rulebook clause
cite_rulebookRead-onlyIdempotent
Retrieve a curated citation from SEPA, CBPR+, or HVPS+ rulebooks for a specific clause, including summary and canonical source URL. Use after discovering clauses via list_rulebook_clauses.
Instructions
Return a curated payments-rulebook citation for a single clause.
Use this to quote one specific rule (with its canonical source URL) once
you know the ``scheme``/``version``/``clause``. To discover which clauses
exist first, call ``list_rulebook_clauses``.
Looks up one well-known rule across the SEPA, CBPR+, and HVPS+
rulebooks and returns a short summary together with the canonical
source URL so an agent can quote the rule and the operator can
verify it against the official document.
The registry is a curated convenience layer, not a verbatim
reproduction of copyrighted text. Always defer to ``source_url``
for authoritative wording before relying on a citation for
compliance or contractual decisions; the returned ``disclaimer``
field repeats this for the calling agent.
Args:
scheme: One of ``"SEPA"``, ``"CBPR+"``, or ``"HVPS+"`` (case
sensitive).
version: The rulebook version (e.g. ``"2025"`` or ``"2026"``).
clause: A kebab-case clause identifier from
``list_rulebook_clauses``.
Returns:
A citation dict ``{"scheme", "version", "clause", "title",
"summary", "source_url", "as_of", "disclaimer"}`` or an
``{"error": ...}`` payload if the citation is not in the
registry.
