Errors

Code	Name	Cause	Remediation
-32600	Invalid request	Malformed JSON-RPC envelope	Check method, jsonrpc, and id fields

-32000	Unauthenticated	Missing Authorization header	Supply a valid Bearer token
-32001	Unauthorized	Grant token expired or revoked	Refresh token via agent.grant.refresh
-32002	Insufficient scope	Grant missing accounts:read scope	Issue new grant with accounts:read scope
-32603	Internal error	Server-side error	Retry with backoff; contact support
