Use the SiYuan kernel API via curl to search, read, create, update, and delete blocks and documents in a self-hosted knowledge base. No extra tools needed -- just curl and an API token.
${HERMES_HOME:-~/.hermes}/.env:
SIYUAN_TOKEN=your_token_here
SIYUAN_URL=http://127.0.0.1:6806
SIYUAN_URL defaults to http://127.0.0.1:6806 if not set.All SiYuan API calls are POST with JSON body. Every request follows this pattern:
curl -s -X POST "${SIYUAN_URL:-http://127.0.0.1:6806}/api/..." \
-H "Authorization: Token $SIYUAN_TOKEN" \
-H "Content-Type: application/json" \
-d '{"param": "value"}'
Responses are JSON with this structure:
{"code": 0, "msg": "", "data": { ... }}
code: 0 means success. Any other value is an error -- check msg for details.
ID format: SiYuan IDs look like 20210808180117-6v0mkxr (14-digit timestamp + 7 alphanumeric chars).
