# SigNoz (connected) Instance in `$SIGNOZ_URL`, API key in `$SIGNOZ_API_KEY`. Talk to `$SIGNOZ_URL` with `curl`. Header: `-H "SIGNOZ-API-KEY: $SIGNOZ_API_KEY"`. - Confirm connectivity: `curl -s -H "SIGNOZ-API-KEY: $SIGNOZ_API_KEY" "$SIGNOZ_URL/api/v1/version" | jq '.'` - List instrumented services: `curl -s -H "SIGNOZ-API-KEY: $SIGNOZ_API_KEY" "$SIGNOZ_URL/api/v1/services" | jq '.'` - Query traces/logs/metrics: POST `$SIGNOZ_URL/api/v3/query_range` with a JSON builder query (start/end epoch-ms + a composite query). Ask the user which service/metric and time window, then build the body. Notes: start with /api/v1/version to confirm the key + URL, then /api/v1/services, then query_range for detail. The query_range body is verbose — build it incrementally.
