Verify

A citation names a claim id, a version and the first 16 hex of the content hash of that version. Fetch the version and compare: the hash must start with the citation's 16 hex, and the ETag of the answer is the same hash.

curl -sI "https://api.btcintel.io/v1/claims/ann_9803?version=7" | grep -i etag
# ETag: "e0c2a158f5c724a865e0b2b5658b6933f7ced290f16ed8b22076572fc45ada82"

curl -s "https://api.btcintel.io/v1/claims/ann_9803?version=7" | jq -r .content_sha256
# e0c2a158f5c724a865e0b2b5658b6933f7ced290f16ed8b22076572fc45ada82
# the first 16 hex are the citation's: btcintel:annotations:9803@v7 sha256:e0c2a158f5c724a8

Every change to the content writes a new version with its own hash; the previous version keeps its hash and its citation, so a quote never changes under the reader.
