OpenAI Integration - CostHawk Documentation

OpenAI supports two CostHawk integration modes.

Mode A: Admin API Sync (Recommended start)

Use an OpenAI organization admin key for low-friction reporting.

Endpoint coverage:
- /v1/organization/usage/completions
- /v1/organization/costs
No app code changes required
Best for quick organization-wide visibility

Admin API Setup

Use this first for reporting coverage.

Mode B: Proxy + Wrapped Key (Advanced controls)

Use proxy routing when you need strict runtime controls and enforcement.

A wrapped key only works against the CostHawk proxy. Do not send ch_sk_... directly to api.openai.com.

If you are not sure whether you have a wrapped key or a CostHawk access token, read Wrapped Keys first.

Proxy URL

POST https://costhawk.ai/api/proxy/openai

This replaces https://api.openai.com/v1/chat/completions.

Python (OpenAI SDK)

from openai import OpenAI

client = OpenAI(
    api_key="ch_sk_your_wrapped_key_here",
    base_url="https://costhawk.ai/api/proxy/openai",
)

response = client.chat.completions.create(
    model="gpt-4.1",
    messages=[{"role": "user", "content": "Hello, world!"}]
)

print(response.choices[0].message.content)

Node.js (OpenAI SDK)

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: "ch_sk_your_wrapped_key_here",
  baseURL: "https://costhawk.ai/api/proxy/openai",
});

const response = await client.chat.completions.create({
  model: "gpt-4.1",
  messages: [{ role: "user", content: "Hello, world!" }],
});

console.log(response.choices[0].message.content);

curl

curl -X POST https://costhawk.ai/api/proxy/openai \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer ch_sk_your_wrapped_key_here" \
  -d '{
    "model": "gpt-4.1",
    "messages": [{"role": "user", "content": "Hello, world!"}]
  }'

Recommended Pattern

Start with Admin API sync for baseline visibility.
Keep MCP enabled for assistant-native analysis and operations.
Add proxy routing for workloads that need policy enforcement or hard-stop limits.
