Count Tokens

Portkey supports the token counting endpoint from anthropic across vertex-ai, bedrock and anthropic in the same format. This allows use to use claude code and any other tooling with the same API signature across providers.

Examples

Python

import anthropic

client = anthropic.Anthropic(
    api_key="dummy", # we will use portkey's provider slug
    default_headers={"x-portkey-api-key": "YOUR_PORTKEY_API_KEY"},
    base_url="https://api.portkey.ai/v1"
)

response = client.messages.count_tokens(
    model="@your-provider-slug/your-model-name",
    system="You are a scientist",
    messages=[{
        "role": "user",
        "content": "Hello, Claude"
    }],
)

print(response.json())
