List traces for a specific agent. Returns trace summaries including input/output content.

Rate limit: 30 requests per minute per organization. Every response carries the standard RateLimit-Limit, RateLimit-Remaining, and RateLimit-Reset (seconds until the window resets) headers; a 429 response additionally carries Retry-After. The limit is enforced per API replica, so the effective budget scales with the number of replicas — treat the headers as a pacing signal rather than an exact global counter. For large exports, page with a small limit, back off on 429, and stay within the 90-day retention window.
