Tamper-evident ledgers of 12 Japanese public data domains with entity search.

Captured live from the server via tools/list.

verify_receipt

Verify a provenance receipt (F-037): recomputes the HMAC signature, checks the intra-receipt chain linkage, and — when the receipt carries an external anchor reference — confirms it against the published F-028 anchor. Returns {valid:true, anchor:"verified"|"pending"|"unverified"} or {valid:false, reason:"signature_mismatch"|"chain_link_broken"|"anchor_mismatch"|"malformed"}. Tamper-evident; price 0.0 (free).

Parameters (2)

querystringrequired
Entity name (company / person), partial match
limitinteger
Max hits per ledger (1-100)

temporal_query

Reconstruct what a ledger item (or items matching a query) officially said AS OF a past date T, by replaying the kept event history. Returns each item's point-in-time state plus an F-037 provenance receipt (observed_at = the state's effective time). existence:false with a first_seen receipt when the item did not yet exist at T; latest state with as_of_clamped:false when T is in the future. Read-only; price 0.0.

Parameters (5)

Stable item id (single-item reconstruction).
querystring
Title substring to reconstruct every matching item (capped at 25). Use instead of item_id.
as_ofstringrequired
ISO-8601 point in time T.
jurisdictionstring
Jurisdiction code (default 'jp').

kyb_report

Turn a company/entity name into a structured English KYB / due-diligence report for foreign-inbound buyers. Aggregates cross-ledger hits (administrative sanctions, licenses, public bids, recalls, etc.) via entity_search, summarizes them (counts + deterministic risk_flags), and attaches an F-037 provenance receipt to EACH hit so the screening is auditable. No model-invented facts: every asserted fact originates from a ledger hit and carries a receipt. Informational only; not legal advice. Price 0.0.

Parameters (2)

querystringrequired
Company / entity name (partial match across all ledgers)
jurisdictionstring
Jurisdiction code (default 'jp')

alerts_create_watch

Create a saved watch: when a NEW matching event appears in a ledger, a notification is pushed to your destination. Filters: ledger (optional), keyword and/or entity (case-insensitive title substring). At least one filter is required. Backfill never fires.

Parameters (5)

entitystring
Additional case-insensitive substring (e.g. company name)

destinationTargetstringrequired
Webhook URL / relay endpoint / email address

alerts_list_watches

No parameters.

alerts_delete_watch

Deactivate a saved watch by id (soft delete; stops future notifications).

Parameters (1)

watchIdstringrequired

freshness_subscribe

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.

ledgerstring
Ledger key, e.g. 'sanction' (omit for all ledgers)
entitystring
Case-insensitive substring of the item title
topicstring
Additional case-insensitive substring
callbackUrlstringrequired
HTTPS endpoint the stale event is POSTed to
