Claude Code setup

export ANTHROPIC_BASE_URL=https://cheapapi.site
export ANTHROPIC_AUTH_TOKEN=sk-tm-YOUR-KEY
# Optional: pin a default model
export ANTHROPIC_MODEL=claude-sonnet-5-5

claude

Paste these three lines in your shell profile (.zshrc or .bashrc) before running claude. Your existing slash commands and /reset all work as before.

Cursor setup

Cursor Settings  ->  Models  ->  OpenAI API Key section

Base URL:   https://cheapapi.site/v1
API Key:    sk-tm-YOUR-KEY

# Then add any model name from the cheapapi catalogue,
# e.g. claude-sonnet-5-5 or gpt-6-sol

Cursor uses the OpenAI-compatible endpoint. You do not need an Anthropic key. Any model in the cheapapi catalogue works.

Cline setup

Cline sidebar  ->  gear icon  ->  API Provider: OpenAI Compatible

OpenAI API Base URL:  https://cheapapi.site/v1
OpenAI API Key:       sk-tm-YOUR-KEY

Select "OpenAI Compatible" as the provider in the Cline sidebar settings. Cline auto-discovers models from the /v1/models endpoint.

Codex CLI setup

export OPENAI_BASE_URL=https://cheapapi.site/v1
export OPENAI_API_KEY=sk-tm-YOUR-KEY

codex "refactor this function to be async"

Codex CLI reads the standard OpenAI env vars. No config file needed.

Python (OpenAI SDK) setup

from openai import OpenAI

client = OpenAI(
    api_key="sk-tm-YOUR-KEY",
    base_url="https://cheapapi.site/v1",
)

resp = client.chat.completions.create(
    model="claude-sonnet-5-5",
    messages=[{"role": "user", "content": "hello"}],
)

The base_url override is the only change. Everything else, streaming, tool calls, function calling, stays the same.

Python (Anthropic SDK) setup

from anthropic import Anthropic

client = Anthropic(
    api_key="sk-tm-YOUR-KEY",
    base_url="https://cheapapi.site",
)

msg = client.messages.create(
    model="claude-sonnet-5-5",
    max_tokens=1024,
    messages=[{"role": "user", "content": "hello"}],
)

The Anthropic SDK accepts a base_url argument. Use the root URL, not /v1.

Node.js (OpenAI SDK) setup

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: "sk-tm-YOUR-KEY",
  baseURL: "https://cheapapi.site/v1",
});

const resp = await client.chat.completions.create({
  model: "claude-sonnet-5-5",
  messages: [{ role: "user", content: "hello" }],
});

Works the same way for TypeScript. The baseURL change is the only line you touch.

Node.js (Anthropic SDK) setup

import Anthropic from "@anthropic-ai/sdk";

const client = new Anthropic({
  apiKey: "sk-tm-YOUR-KEY",
  baseURL: "https://cheapapi.site",
});

const msg = await client.messages.create({
  model: "claude-sonnet-5-5",
  maxTokens: 1024,
  messages: [{ role: "user", content: "hello" }],
});

Use the root URL without /v1 for the Anthropic SDK. baseURL replaces the entire host.

curl setup

curl https://cheapapi.site/v1/chat/completions \
  -H "Authorization: Bearer sk-tm-YOUR-KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-sonnet-5-5",
    "messages": [{"role": "user", "content": "hello"}]
  }'

OpenAI-compatible endpoint. Anthropic-native endpoint also available at /messages for models that support it.

n8n setup

Credentials  ->  New  ->  OpenAI API

Base URL:  https://cheapapi.site/v1
API Key:   sk-tm-YOUR-KEY

# In any OpenAI node, select your new credential.
# Use model names from the cheapapi catalogue.

n8n uses OpenAI-compatible credentials. You can use any model in your workflows by typing the model name directly.

Hermes Agent setup

# ~/.hermes/config.yaml
provider: anthropic
api_key: sk-tm-YOUR-KEY
base_url: https://cheapapi.site

# Or use as a custom OpenAI provider:
provider: openai
api_key: sk-tm-YOUR-KEY
base_url: https://cheapapi.site/v1

Hermes reads base_url from config.yaml. The Anthropic provider route is recommended for Claude models.
