Claude Agent SDK | AI Gateway & Observability

Observability

Instrument your agents with OpenTelemetry using the SDK’s hooks system to capture traces for every agent turn and tool use.

AI Gateway Beta

Route your Claude calls through the AI Gateway with a single base URL change. Zero vendor lock-in: always run on the best model at the lowest cost for your use case.

Observability

Overview

The Claude Agent SDK (claude-agent-sdk) drives the Claude CLI as a programmable agent supporting multi-turn conversations, tool use, and MCP servers. Use the SDK’s built-in hooks system to attach OpenTelemetry instrumentation at key execution points. Every tool invocation becomes a span, and the full agent workflow is captured as a trace in orq.ai without modifying your agent logic.

Key Benefits

Full Agent Visibility

Track every agent turn, tool use, and LLM call with detailed traces and analytics

Zero Code Changes

Attach observability through hooks without modifying your agent logic

Cost Tracking

Real-time cost and token usage per agent run synced to Orq.ai

Tool Inspection

Inspect every tool input and output with full execution context

Prerequisites

An Orq.ai account and API Key
Python 3.10 or higher, or Node.js 18 or higher

Configuration

Set up the OTel tracer provider to export spans to Orq.ai:

TypeScript
Python

TypeScript

import { NodeSDK } from '@opentelemetry/sdk-node';
import { OTLPTraceExporter } from '@opentelemetry/exporter-trace-otlp-http';
import { ClaudeAgentSDKInstrumentation } from '@arizeai/openinference-instrumentation-claude-agent-sdk';
import * as ClaudeAgentSDKModule from '@anthropic-ai/claude-agent-sdk';

const ClaudeAgentSDK = { ...ClaudeAgentSDKModule };
const instrumentation = new ClaudeAgentSDKInstrumentation();
instrumentation.manuallyInstrument(ClaudeAgentSDK);

const sdk = new NodeSDK({
  traceExporter: new OTLPTraceExporter({
    url: 'https://api.orq.ai/v2/otel/v1/traces',
    headers: {
      Authorization: `Bearer ${process.env.ORQ_API_KEY}`,
    },
  }),
  instrumentations: [instrumentation],
});

sdk.start();

Python

import os
from opentelemetry.sdk.trace import TracerProvider
from opentelemetry.sdk.trace.export import BatchSpanProcessor
from opentelemetry.exporter.otlp.proto.http.trace_exporter import OTLPSpanExporter
from opentelemetry import trace
from openinference.instrumentation.claude_agent_sdk import ClaudeAgentSDKInstrumentor

tracer_provider = TracerProvider()
tracer_provider.add_span_processor(
    BatchSpanProcessor(
        OTLPSpanExporter(
            endpoint="https://api.orq.ai/v2/otel/v1/traces",
            headers={"Authorization": f"Bearer {os.environ['ORQ_API_KEY']}"},
        )
    )
)
trace.set_tracer_provider(tracer_provider)

ClaudeAgentSDKInstrumentor().instrument(tracer_provider=tracer_provider)
tracer = trace.get_tracer(__name__)

Basic Example

TypeScript
Python

Spread the imported SDK module into a mutable namespace, then call ClaudeAgentSDKInstrumentation.manuallyInstrument(...) before sdk.start(). The instrumentation patches every query() call, tool use, and subagent into spans automatically.

TypeScript

import { NodeSDK } from '@opentelemetry/sdk-node';
import { OTLPTraceExporter } from '@opentelemetry/exporter-trace-otlp-http';
import { ClaudeAgentSDKInstrumentation } from '@arizeai/openinference-instrumentation-claude-agent-sdk';
import * as ClaudeAgentSDKModule from '@anthropic-ai/claude-agent-sdk';

const ClaudeAgentSDK = { ...ClaudeAgentSDKModule };
const instrumentation = new ClaudeAgentSDKInstrumentation();
instrumentation.manuallyInstrument(ClaudeAgentSDK);

const sdk = new NodeSDK({
  traceExporter: new OTLPTraceExporter({
    url: 'https://api.orq.ai/v2/otel/v1/traces',
    headers: {
      Authorization: `Bearer ${process.env.ORQ_API_KEY}`,
    },
  }),
  instrumentations: [instrumentation],
});

sdk.start();

const prompt = 'What is the capital of France?';
console.log(`User: ${prompt}\n`);

for await (const message of ClaudeAgentSDK.query({ prompt })) {
  if ('result' in message && typeof message.result === 'string') {
    console.log(`Assistant: ${message.result}`);
  }
}

await sdk.shutdown();
console.log('\nTraces exported to orq.ai. View them at https://my.orq.ai');

Call ClaudeAgentSDKInstrumentor().instrument() before any agent call. The instrumentor wraps every tool invocation, LLM turn, and subagent in spans automatically. Drive the agent via ClaudeSDKClient (instead of the standalone query() generator) and wrap the call in a root agent-workflow span to stamp the prompt and the final cost.

                    print(f"\nCost: ${message.total_cost_usd or 0:.6f} | Turns: {message.num_turns}")

    tracer_provider.force_flush()
    print("\nTraces exported to orq.ai. View them at https://my.orq.ai")

AI Gateway

This feature is in Beta. Traces are not supported while using the AI Gateway with the Claude Agent SDK.

Overview

Route the Claude Agent SDK’s model calls through Orq.ai’s AI Gateway without changing any agent logic. The SDK drives the Claude CLI, which reads ANTHROPIC_BASE_URL and ANTHROPIC_AUTH_TOKEN from the environment, so pointing those variables at the gateway routes every turn through Orq.ai.

For the raw Claude Messages API without the agent runtime, see the Anthropic SDK integration.

Configuration

Set the following environment variables before running the agent:

export ANTHROPIC_BASE_URL="https://api.orq.ai/v3/anthropic"
export ANTHROPIC_AUTH_TOKEN="$ORQ_API_KEY"
export ANTHROPIC_API_KEY=""  # set empty so the SDK does not call the Anthropic API directly
export ANTHROPIC_MODEL="anthropic/claude-sonnet-4-6"  # the anthropic/ prefix is required

Basic Example

With the environment variables set, every agent run routes through the AI Gateway with no change to the calling code:

TypeScript
Python

TypeScript

import { query } from '@anthropic-ai/claude-agent-sdk';

const prompt = 'What is the capital of France?';

for await (const message of query({ prompt })) {
  if ('result' in message && typeof message.result === 'string') {
    console.log(message.result);
  }
}

Python

import asyncio
from claude_agent_sdk import (
    ClaudeSDKClient,
    AssistantMessage,
    TextBlock,
)


async def main():
    async with ClaudeSDKClient() as client:
        await client.query("What is the capital of France?")
        async for message in client.receive_response():
            if isinstance(message, AssistantMessage):
                for block in message.content:
                    if isinstance(block, TextBlock):
                        print(block.text)


asyncio.run(main())
