respan-instrumentation-anthropic

Respan instrumentation plugin for the Anthropic Python SDK.

This package patches Anthropic client calls and emits spans using the Respan/Traceloop GenAI attribute shape used across this repository.

Install

pip install respan-instrumentation-anthropic

Quickstart

import os

from anthropic import Anthropic
from respan import Respan
from respan_instrumentation_anthropic import AnthropicInstrumentor

respan = Respan(
    api_key=os.environ["RESPAN_API_KEY"],
    instrumentations=[AnthropicInstrumentor()],
)

client = Anthropic(api_key=os.environ["ANTHROPIC_API_KEY"])

message = client.messages.create(
    model="claude-3-5-haiku-latest",
    max_tokens=128,
    messages=[{"role": "user", "content": "Write one line about tracing."}],
)

print(message.content)
respan.flush()

Notes

• The instrumentor patches both Anthropic and AsyncAnthropic.
• messages.create() and streaming responses are traced.
• Managed agent session streaming is also captured when available through the Anthropic SDK.
