Integration Pipeline
All 5 data source integration paths verified end-to-end:
| Integration | How It Works |
|---|---|
| Agent Gateway | Route LLM calls through the Metrx proxy — zero code changes |
| Langfuse | Connect your Langfuse project for automatic import (15-min sync) |
| LangSmith | Connect your LangSmith project for automatic import (15-min sync) |
| OpenTelemetry | Send OTLP traces — Metrx filters LLM-related spans automatically |
| Python SDK | metrx.init() auto-instruments OpenAI and Anthropic clients |
Added
- Canonical batch event ingest endpoint with dual SDK format support
- Python SDK streaming support for OpenAI and Anthropic
- Circuit breaker in gateway logger (5 failures → 30s open, auto-recovery)
- Bounded retry and queue in Python SDK transport
