Check an exported document.
Every claim in a verified export links to its source, and each cited source's content is hash-verified at export. The bundle's manifest is signed, which makes it tamper-evident: paste it below to check the signature against XESO's published key.
What a valid signature means
A valid signature means the manifest is byte-identical to what XESO signed at export time — the citation list, the recorded source hashes, and the export date have not been altered since. It does not judge whether the underlying sources are true; it gives you the audited record of what the document cited and when.
The verification key is published at GET https://xeso.ai/api/verify (Ed25519, SPKI DER, base64), so you can also verify a manifest offline with standard tooling.
