Japanese dream-interpretation agent API. Returns a deterministic 5-axis dream profile plus a long-form research-cited report (result schema agent-dream-insight.deep.v1). Japanese or English output. Dream text is never stored or logged. Async by default: the paid POST returns a job id in seconds; fetch the result with a plain free HTTP GET (no x402 client) at /api/agent/interpret/result/{job_id} (ready in ~20s). options.sync=true for one synchronous response (10-25s; client timeout 60s+).
