JIDEC Verification Ledger API is one of 7 APIs that [HORIZON SHIELD](https://apis.io/providers/horizonshield-dev/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Transparency Ledger, Verification, Open Data, MCP, and A2A. The published artifact set on APIs.io includes API documentation.

Append-only, Bitcoin-anchored (OpenTimestamps) public ledger of the verification process at https://ledger.horizonshield.dev: an index of anchored entries, per-entry raw bytes and .ots proofs, citation resolution (/cite/{citation}), executable verification recipes (/verify/{n}), anchored verification paths and replay, a witness intake for third-party conduct walks, and agreement records. Discovery is an RFC 9727 api-catalog served as application/linkset+json, an RFC 9116 security.txt, an llms.txt verification guide and a JWS-signed A2A card; a read-only MCP twin (4 tools) runs at https://jidec.horizonshield.dev/mcp. The service states it is SCITT-shaped but not a conformant SCITT transparency service.
