API monitoring: every API, full analysis, dashboards and service health (M16) #63

API monitoring for the workspace's own APIs: any project, written in any framework, sends its request records, health and uptime to Yuva through a middleware or OpenTelemetry, and the workspace gets request volume, errors and latency per route, consumers, alerts and uptime, custom dashboards like Grafana, the health of every service and its dependencies, and public status pages on the workspace's own domain. Separate from visitor analytics (#42, M15), which counts visits and cannot compute percentiles from event props.

Steps (each its own issue, each shippable):

• M16.1 Record and count API requests — M16.1 Record and count API requests #64
• M16.2 Every API stack: SDK middleware and OpenTelemetry — M16.2 Every API stack: SDK middleware and OpenTelemetry #65 (needs M16.1, Web SDK: server helpers for identity tokens, webhooks and analytics (useyuva/server) #60–Nitro module and Nuxt server integration: identity route, webhooks, analytics (useyuva/nitro) #62)
• M16.3 Full API analysis: breakdowns, consumers, comparisons — M16.3 Full API analysis: breakdowns, consumers, comparisons #66 (needs M16.1)
• M16.4 Alerts, uptime checks, reports, MCP — M16.4 API alerts, uptime checks, reports, MCP #67 (needs M16.3)
• M16.5 Sharing, export and retention — M16.5 API monitoring sharing, export and retention #68 (needs M16.1)
• M16.6 Custom dashboards like Grafana — M16.6 Custom dashboards like Grafana #69 (needs M16.3)
• M16.7 Service health: checks, dependencies, incidents — M16.7 Service health: checks, dependencies, incidents #70 (needs M16.4)
• M16.8 Public status pages on a custom domain — M16.8 Public status pages on a custom domain #71 (needs M16.7)

Web SDK server helpers this builds on: #60, #61, #62.

Decided in docs/architecture.md › API monitoring (M16): an API is an analytics property of kind api;
no row per request is stored (minute, hour and day rollups with mergeable sketches); sampling is off by
default and, when an SDK samples, shows as "estimated".
