GPT-5.4 Mini API

Quickstart

SkillBoss Wholesale is OpenAI SDK-compatible — point any OpenAI client at https://api.skillboss.co/v1 and pass your wholesale key as a bearer token. Works out of the box with the official OpenAI Python and Node SDKs, Vercel AI SDK, LangChain, LlamaIndex, and most other OpenAI-shaped clients.

bashcurl https://api.skillboss.co/v1/chat/completions \
  -H "Authorization: Bearer $SKILLBOSS_WHOLESALE_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "openai/gpt-5.4-mini",
    "messages": [
      {"role": "user", "content": "Hello"}
    ]
  }'

Your first 200 response is the fastest way to confirm setup. From there, swap in your real prompt and tune the model-specific parameters listed below.

Authentication

Every request must include your wholesale key. The header name depends on the endpoint — match the SDK you're using:

bashAuthorization: Bearer $SKILLBOSS_WHOLESALE_KEY

Treat the wholesale key like a password — never commit it to source control or ship it in client-side bundles. Rotate from the wholesale dashboard if exposed. Standard (non-wholesale) console keys are rejected at the gateway with 401.

Code examples

pythonimport os
from openai import OpenAI

client = OpenAI(
    api_key=os.environ["SKILLBOSS_WHOLESALE_KEY"],
    base_url="https://api.skillboss.co/v1",
)

resp = client.chat.completions.create(
    model="openai/gpt-5.4-mini",
    messages=[{"role": "user", "content": "Hello"}],
)
print(resp.choices[0].message.content)

typescriptimport OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.SKILLBOSS_WHOLESALE_KEY,
  baseURL: "https://api.skillboss.co/v1",
});

const resp = await client.chat.completions.create({
  model: "openai/gpt-5.4-mini",
  messages: [{ role: "user", content: "Hello" }],
});

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