omni-usage-logs

Overview

Access detailed call logs and usage analytics. Filter by provider, model, time range, status, and cost. Export logs and aggregate token usage across all connections.

Authentication

All requests require a valid Bearer token or session cookie. Obtain a token via POST /api/auth/login or configure REQUIRE_API_KEY=false for local development.

GET /api/usage/budget

Get usage budget status

Returns current budget limits and consumption.

curl https://localhost:20128/api/usage/budget \
  -H "Authorization: Bearer $NERVE_TOKEN"

POST /api/usage/budget

  -d '{}'

GET /api/usage/cache-health

Get prompt-cache health summary

Summarizes the write/read cache ratio from call_logs for a time window: distribution (p50/p90/p99/max of cache-write tokens), warm/cold/rewrite/uncached call counts, the "heavy write" outlier share (10x the window median, floored at 1024 tokens — Anthropic's cache-creation minimum), and a per-model breakdown. Only successful (status = 200) calls with a non-null cache column are counted.

curl https://localhost:20128/api/usage/cache-health \
  -H "Authorization: Bearer $NERVE_TOKEN"

GET /api/usage/model-latency-stats

Get per-model/provider latency statistics

Aggregates usage_history rows into per-(provider, model) latency stats (avg/p50/p95/p99, std-dev, TTFT, tokens/sec) over a rolling window. Falls back from successful-only to all-sample rows when the successful count is below minSamples.
