# APIToolkit (Monoscope)

**Canonical:** https://apis.io/providers/apitoolkit/  
**APIs profiled:** 7

APIToolkit (now Monoscope) is an open-source-friendly API observability and monitoring platform that helps teams find and fix production issues before customers notice. It unifies logs, traces, metrics, errors, monitors, and session replay across 17+ framework SDKs and 780+ OpenTelemetry integrations. The platform exposes a REST API (api.monoscope.tech/api/v1) for programmatic access to metrics, telemetry schema, and monitors, plus a hosted MCP server with ~50 auto-derived tools and workflow tools (analyze_issue, find_error_patterns, search_events_nl) and four Claude Code skills (investigate, triage, kql-reference, instrument) so agents can drive observability from the terminal or any LLM client. The apitoolkit.io domain now redirects to monoscope.tech.
