SDKs and other tools

Any tool that lets you set a base URL and API key for OpenAI or Anthropic can use Vikey. The rule:

Tool uses the format	Base URL	Example models
OpenAI	https://api.vikey.ai/v1	openai/gpt-6.1-sol, vikey/agent-gpt
Anthropic	https://api.vikey.ai	anthropic/claude-sonnet-5.5, vikey/agent-coding

Models from any provider work through both formats. For example, GPT models work through the Anthropic SDK, and Claude models through the OpenAI SDK.

OpenAI SDK

Python

from openai import OpenAI

client = OpenAI(base_url="https://api.vikey.ai/v1", api_key="YOUR_API_KEY")

stream = client.chat.completions.create(
    model="anthropic/claude-sonnet-5.5",
    messages=[{"role": "user", "content": "Explain recursion in two sentences."}],
    stream=True,
)
for chunk in stream:
    print(chunk.choices[0].delta.content or "", end="")

Node.js

import OpenAI from 'openai'

const client = new OpenAI({ baseURL: 'https://api.vikey.ai/v1', apiKey: 'YOUR_API_KEY' })

const stream = await client.chat.completions.create({
  model: 'anthropic/claude-sonnet-5.5',
  messages: [{ role: 'user', content: 'Explain recursion in two sentences.' }],
  stream: true,
})
for await (const chunk of stream) process.stdout.write(chunk.choices[0]?.delta?.content || '')

Anthropic SDK

Python

import anthropic

client = anthropic.Anthropic(base_url="https://api.vikey.ai", api_key="YOUR_API_KEY")

message = client.messages.create(
    model="anthropic/claude-sonnet-5.5",
    max_tokens=1024,
    messages=[{"role": "user", "content": "Explain recursion in two sentences."}],
)
print(message.content[0].text)

Node.js

import Anthropic from '@anthropic-ai/sdk'

const client = new Anthropic({ baseURL: 'https://api.vikey.ai', apiKey: 'YOUR_API_KEY' })

const message = await client.messages.create({
  model: 'anthropic/claude-sonnet-5.5',
  max_tokens: 1024,
  messages: [{ role: 'user', content: 'Explain recursion in two sentences.' }],
})
console.log(message.content[0].text)

Through environment variables

Many tools read these standard variables. If yours does, set:

# OpenAI-format tools
export OPENAI_BASE_URL=https://api.vikey.ai/v1
export OPENAI_API_KEY=YOUR_API_KEY

# Anthropic-format tools
export ANTHROPIC_BASE_URL=https://api.vikey.ai
export ANTHROPIC_AUTH_TOKEN=YOUR_API_KEY

Then choose a Vikey model id in that tool’s settings.
