Three requests, one terminal, under a minute. Every number on this page comes from the first one.

1. 1 · fetch the live root index

   curl -s https://usedeed.app/api/journal-roots

   Serves the finality counts above and every public root hash. If this page and that response disagree, trust the response.

2. 2 · fetch the root artifact

   curl -s https://usedeed.app/api/journal-roots/<root-hash>

   Every public entry under the root, hash-linked entry to entry — each record carries its own digest and the digest of the one before it. Recompute any of them and it must match.

3. 3 · fetch the anchor artifact

   curl -s https://usedeed.app/api/journal-anchors/<root-hash>

   The timestamp receipt for the same hash. The calendar address inside it resolves on OpenTimestamps infrastructure DEED does not control — that receipt, not this site, is the proof.

Signature check: the public MCP endpoint at /oss/mcp exposes a verify tool (deed_verify_journal_root) that checks a root hash against the stored artifact, and verifies the hash and Ed25519 signature offline when you supply the full signed root object. The open-source engine ships the same verifier.
