AI Provider Bridge — Unified API for Anthropic/OpenAI/Google/xAI/Mistral/Ollama

One interface to call 6 AI providers. Swap models with a config change, not a code rewrite. Zero external dependencies.

Unified interface for 6 AI providers. One function call, any model.

Supported Providers

Provider	Models	API Key Env Var
Anthropic	Claude Opus, Sonnet, Haiku	`ANTHROPIC_API_KEY`
OpenAI	GPT-4o, GPT-4, GPT-3.5	`OPENAI_API_KEY`
Google	Gemini Pro, Gemini Flash	`GOOGLE_API_KEY`
xAI	Grok	`XAI_API_KEY`
Mistral	Mistral Large, Medium, Small	`MISTRAL_API_KEY`
Ollama	Any local model	None (local)

Usage

javascript

const { AIBridge } = require('./src/ai-bridge');

const ai = new AIBridge({
  currentModel: 'anthropic/claude-sonnet-4-20250514',
  anthropicApiKey: process.env.ANTHROPIC_API_KEY,  // only needed for Anthropic models
  openaiApiKey:    process.env.OPENAI_API_KEY,      // only needed for OpenAI models
  googleApiKey:    process.env.GOOGLE_API_KEY,      // only needed for Google models
  xaiApiKey:       process.env.XAI_API_KEY,         // only needed for xAI models
  mistralApiKey:   process.env.MISTRAL_API_KEY,     // only needed for Mistral models
  ollamaHost:      'http://127.0.0.1:11434'         // optional, default shown
});

const response = await ai.sendMessage('What is the capital of France?');
console.log(response);

Switching Providers

Change the model — provider is inferred from the prefix:

javascript

// Switch from cloud to local Ollama
ai.setModel('ollama/llama3.1:8b');

// Same interface
const response = await ai.sendMessage('Same question, free model');

Model prefix → provider mapping:

anthropic/ → Anthropic API
openai/ → OpenAI API
google/ → Google Gemini API
xai/ → xAI Grok API
mistral/ → Mistral API
ollama/ → Local Ollama (no API key needed)

Zero Dependencies

Uses only Node.js built-in `https` and `http` modules. No npm install needed.

Changelog

v1.0.3

Fixed API usage examples — config object uses camelCase property names (anthropicApiKey, openaiApiKey, googleApiKey, xaiApiKey, mistralApiKey), not flat apiKey or env var names. Model prefix determines provider (anthropic/model-name). Clarified sendMessage() as the correct method name.

v1.0.2

Removed require('./token-compressor') reference entirely. TokenCompressor is now an inlined no-op pass-through class — no missing dependency, no external file needed. To enable compression, install the companion token-compressor skill and swap the class as noted in the code comments.
Removed automatic "Do not store or train on this data." appended to system prompts in OpenAI-compatible requests. This is the caller's responsibility — pass it via setSystemPrompt() if needed.

v1.0.1

TokenCompressor dependency made optional — no-op fallback added when ./token-compressor is not present. Bridge works without it; messages pass through uncompressed.
Removed buildSystemPrompt() and workspaceContext option. These allowed embedding workspace files into system prompts sent to external APIs — data exposure risk. Use setSystemPrompt() directly.
Added env: section to frontmatter declaring required API keys per provider. All optional — only keys for providers you use are needed.
