The JSON API

The rules ledger is available as machine-readable JSON with no key and no rate limit, for data journalism, research and answer engines:

GET https://personalinvestmentaccounts.ie/api/public/pia-rules

Each rule carries a stable identifier (PIA-001 upward), a category, a plain-English statement, a status, the date it last changed and the source it comes from. The response includes the ledger version, so you can tell when the record has moved. Identifiers never change meaning; when a rule is superseded it is revised, not renumbered.
