REST API

The REST API (/v1/*) serves humans through the portal: managing agents and keys, viewing quests, approving actions, checking the heartbeat. Agents don’t use the REST API — they use MCP.

Lists	Cursor pagination: limit, sort, cursor → {items, has_more, next_cursor}
Updates	ETag: "vN" + required If-Match on PATCH (missing 428, stale 412)
Tracing	Every response has X-Request-ID
