freshness_subscribe
ActiveTool of Japan Public Ledgers MCP
Subscribe a machine/AI pipeline to ledger-change notifications: when a matching record changes, a signed "stale" event (with an F-037 receipt proving the change) is POSTed to your callback_url so your RAG/index can re-index. Filters: ledger (optional), entity and/or topic (case-insensitive title substring). At least one filter is required. Body is HMAC-signed with your secret (X-Receipt-Signature). Backfill never fires. Price 0.0.
