Quickstart

Pick the tool you use and make your first request in about two minutes.

Before you start

You need an API key. Create an account, buy a credit pack in your dashboard, and your key arrives by email once the payment confirms. Store it somewhere safe, then make it available to your tools:

export EVOLVED_API_KEY="your_key_here"

Pick your tool

Choose what you use. You can set up more tools later with the same key.

  1. Point Claude Code at evolved.to

    terminal
    export ANTHROPIC_BASE_URL="https://api.evolved.to"
export ANTHROPIC_AUTH_TOKEN="$EVOLVED_API_KEY"
export ANTHROPIC_MODEL="claude-opus-5"

claude

  2. Start coding

    Claude Code now runs through your key. Change models any time with /model. Full guide: Claude Code.

  1. Add evolved.to as a provider

    ~/.codex/config.toml
    # ~/.codex/config.toml
model = "gpt-5"
model_provider = "evolved"

[model_providers.evolved]
name = "evolved.to"
base_url = "https://api.evolved.to/v1"
env_key = "EVOLVED_API_KEY"
wire_api = "responses"

  2. Run Codex

    codex

    Full guide: Codex.

  1. Open Cursor Settings → Models

    Under API Keys, paste your evolved.to key into the OpenAI API Key field.

  2. Override the base URL

    Enable Override OpenAI Base URL and enter https://api.evolved.to/v1. Full guide: Cursor.

  1. Install the SDK

    pip install anthropic

  2. Send your first message

    main.py
    import os
import anthropic

client = anthropic.Anthropic(
    base_url="https://api.evolved.to",
    api_key=os.environ["EVOLVED_API_KEY"],
)

message = client.messages.create(
    model="claude-opus-5",
    max_tokens=16000,
    messages=[{"role": "user", "content": "Hello, Claude"}],
)

for block in message.content:
    if block.type == "text":
        print(block.text)

  1. Install the SDK

    npm install openai

  2. Send your first request

    index.ts
    import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://api.evolved.to/v1",
  apiKey: process.env.EVOLVED_API_KEY,
});

const response = await client.responses.create({
  model: "gpt-5",
  input: "Hello!",
});

console.log(response.output_text);

Verify your key

List the models your key can call. A JSON list means everything is wired up correctly.

curl https://api.evolved.to/v1/models \
  -H "Authorization: Bearer $EVOLVED_API_KEY"
