Query Histogram

Get histogram distribution for a metric.

Metrics: lcp, fcp, cls, inp, ttfb, tbt, dns_lookup, tcp_connection, etc.

Buckets: Define boundaries as array, e.g., [0, 500, 1000, 2500, 4000] creates buckets: <0, 0-500, 500-1000, 1000-2500, 2500-4000, 4000+

Example for LCP histogram:

{    "time_range": {"from": "2024-01-01", "to": "2024-01-08"},    "metric": "lcp",    "buckets": [0, 500, 1000, 2500, 4000]}
