Quick Start

Sign in, create an API key, and confirm the Base URL. Then choose the request style that fits your client. VoltAI is a drop-in gateway: existing OpenAI and Anthropic clients work without code changes beyond the base URL and key.

  1. 1

    Create account & sign in

    Sign up for a VoltAI account, then log in to the console at console.voltai.one.

  2. 2

    Get API key

    Open the API Keys page in the console and create a new key (starts with sk-).

  3. 3

    Set Base URL

    Point your client's base URL to the VoltAI endpoint below, then send a test request.

Base URLhttps://api.voltai.one

Request methods

VoltAI supports both common LLM calling styles. Use the one your client already speaks — both route to the same models with transparent pass-through (no silent model swaps).

POST/v1/chat/completions

OpenAI-compatible

For OpenAI SDKs, LangChain, and existing Chat Completions clients. Auth with Authorization: Bearer.

POST/v1/messages

Anthropic-compatible

For Claude / Anthropic Messages clients. Auth with x-api-key + anthropic-version header.
