-H 'Content-Type: application/json' \
-H 'Accept: application/json, text/event-stream' \
-d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-06-18","capabilities":{},"clientInfo":{"name":"example","version":"1.0.0"}}}'Authentication behavior
Initialization and the public about tool do not require credentials, so clients and auditors can complete discovery safely. Catalog and account tools require a Nautilinks key sent as Authorization: Bearer …. Prefer sn_test_ for write-path testing.
Available jobs
