Provider: AWS Bedrock

Use Respan Gateway to call AWS Bedrock models (Anthropic Claude on Bedrock, Meta Llama, Amazon Nova, and the rest) while keeping unified observability (logs, cost, latency, reliability) in Respan.

Quick setup

Send your first request

Pick the integration that matches your stack. The base URL is https://api.respan.ai/api and the only key needed is your RESPAN_API_KEY.

1
from openai import OpenAI
2
3
client = OpenAI(
4
    api_key="YOUR_RESPAN_API_KEY",
5
    base_url="https://api.respan.ai/api",
6
)
7
8
response = client.chat.completions.create(
9
    model="bedrock/anthropic.claude-3-5-sonnet-20241022-v2:0",
10
    messages=[{"role": "user", "content": "Hello, Bedrock!"}],
11
)
12
print(response.choices[0].message.content)

More integrations

Bedrock models work with every Respan gateway integration:

• OpenAI SDK
• LangChain
• LangGraph
• LlamaIndex
• Pydantic AI
• Respan native (OTel)

Switch models

Change the model parameter to call any supported model through the same client. Use the bedrock/ prefix to disambiguate when routing across providers. Browse the full list on the Models page.

3
client.chat.completions.create(model="bedrock/amazon.nova-pro-v1:0", messages=messages)
4
client.chat.completions.create(model="openai/gpt-5.5", messages=messages)
5
client.chat.completions.create(model="anthropic/claude-sonnet-4-5-20250929", messages=messages)

Use your own AWS Bedrock key (BYOK)

Credits are the default path. If you’d rather bill AWS directly, attach your own IAM credentials.

Override credentials per model (Optional)

Use credential_override when one model on a request should use a different AWS account or region than the default.

  "customer_credentials": {

    "bedrock": {
4
      "aws_access_key_id": "YOUR_AWS_ACCESS_KEY_ID",
5
      "aws_secret_access_key": "YOUR_AWS_SECRET_ACCESS_KEY",
6
      "aws_region_name": "us-east-1"

    "bedrock/anthropic.claude-3-5-sonnet-20241022-v2:0": {

      "aws_access_key_id": "ANOTHER_AWS_ACCESS_KEY_ID",
12
      "aws_secret_access_key": "ANOTHER_AWS_SECRET_ACCESS_KEY",
13
      "aws_region_name": "us-west-2"
14
    }
15
  }
16
}

Log without proxying (Optional)

Already calling Bedrock directly? Send logs to Respan asynchronously to track cost, latency, and performance for those external calls.

1
import requests
2
3
requests.post(
4
    "https://api.respan.ai/api/request-logs/create/",
5
    headers={
6
        "Authorization": "Bearer YOUR_RESPAN_API_KEY",
7
        "Content-Type": "application/json",
8
    },
9
    json={
10
        "model": "bedrock/anthropic.claude-3-5-sonnet-20241022-v2:0",
11
        "prompt_messages": [{"role": "user", "content": "Hello, how are you?"}],
12
        "completion_message": {"role": "assistant", "content": "Hello from Bedrock through Respan."},
13
        "cost": 0.001,
14
        "generation_time": 1.2,
15
        "customer_params": {"customer_identifier": "user_123"},
16
    },

)
