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.

Endpoints

GET /api/usage/analytics

Get usage analytics

curl https://localhost:20128/api/usage/analytics \
  -H "Authorization: Bearer $OMNIROUTE_TOKEN"

GET /api/usage/call-logs

Get call logs

curl https://localhost:20128/api/usage/call-logs \
  -H "Authorization: Bearer $OMNIROUTE_TOKEN"

GET /api/usage/call-logs/{id}

Get a specific call log

curl https://localhost:20128/api/usage/call-logs/{id} \
  -H "Authorization: Bearer $OMNIROUTE_TOKEN"

GET /api/usage/{connectionId}

Get usage for a specific connection

curl https://localhost:20128/api/usage/{connectionId} \
  -H "Authorization: Bearer $OMNIROUTE_TOKEN"

GET /api/usage/history

Get usage history

curl https://localhost:20128/api/usage/history \
  -H "Authorization: Bearer $OMNIROUTE_TOKEN"

GET /api/usage/logs

Get usage logs

curl https://localhost:20128/api/usage/logs \
  -H "Authorization: Bearer $OMNIROUTE_TOKEN"

GET /api/usage/proxy-logs

Get proxy logs

curl https://localhost:20128/api/usage/proxy-logs \
  -H "Authorization: Bearer $OMNIROUTE_TOKEN"

GET /api/usage/request-logs

Get request logs

curl https://localhost:20128/api/usage/request-logs \
  -H "Authorization: Bearer $OMNIROUTE_TOKEN"

GET /api/usage/budget

Get usage budget status

Returns current budget limits and consumption.

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

POST /api/usage/budget

Configure usage budget

Set or update budget limits for usage tracking.

curl -X POST https://localhost:20128/api/usage/budget \
  -H "Authorization: Bearer $OMNIROUTE_TOKEN"
  -H "Content-Type: application/json" \
  -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 $OMNIROUTE_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.

curl https://localhost:20128/api/usage/model-latency-stats \
  -H "Authorization: Bearer $OMNIROUTE_TOKEN"
