OpenAI SDK

Configuration

• Install the official openai package in your application.
• Set PRISMATIC_API_KEY server-side and map it to OPENAI_API_KEY if the SDK expects that variable.
• Set the SDK baseURL / base_url to https://api.prismaticapi.com/v1.
• Use any public model ID returned by GET /v1/models.

Example

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.PRISMATIC_API_KEY,
  baseURL: "https://api.prismaticapi.com/v1"
});

const completion = await client.chat.completions.create({
  model: "claude-sonnet-4-6",
  messages: [{ role: "user", content: "Write three product taglines." }],
  max_tokens: 400
});

import os
from openai import OpenAI

client = OpenAI(
    api_key=os.environ["PRISMATIC_API_KEY"],
    base_url="https://api.prismaticapi.com/v1",
)

completion = client.chat.completions.create(
    model="claude-sonnet-4-6",
    messages=[{"role": "user", "content": "Write three product taglines."}],
    max_tokens=400,
)

Recommended models

• claude-sonnet-4-6 — strong model for reasoning, refactors and coding agents.
• claude-haiku-4-5 — fast option for autocomplete, small questions and lightweight tasks.
• deepseek-v3-2 or another public ID — alternative based on your active catalog and plan.

Troubleshooting

Notes

• /v1/chat/completions, /v1/responses and /v1/models use the OpenAI-compatible surface.
• Keep the key out of browser code and mobile clients.
• Streaming works when the SDK request sets stream: true.
