Status History

Trailing-window SLA history per source. Public, no auth.

Pairs with /v1/status (which is point-in-time). This endpoint returns the timeline that backs the /status page's uptime chart. Default window is 24 hours (86400s). Max is 7 days.

Memory rule compliance: returns metadata only (SLA classification

• age). No prices touched. Reads from a Redis ring buffer populated by the collector's source_quality_history_loop; the buffer is bounded so the endpoint cost is constant regardless of uptime.

An empty sources always comes with a _note saying why, and newest_sample_age_s when the buffer holds samples older than the requested window, so a stopped sampler is distinguishable from a quiet one without opening a support ticket.

Returns: { "as_of": "...", "window_s": 86400, "sources": { "pinnacle": [ {"ts": ..., "sla": "ok", "age_s": 4.2}, ... ], ... } }
