lex-xai

Legion Extension for the xAI Grok API.

Wraps the xAI Grok REST API as named runners consumable by any LegionIO task chain. Provides chat completions, embeddings, and model listing. Use this extension when you need direct access to the xAI API surface within the LEX runner/actor lifecycle. For simple chat/embed workflows, consider legion-llm instead.

Add to your Gemfile:

gem 'lex-xai'

require 'legion/extensions/xai/client'

client = Legion::Extensions::Xai::Client.new(api_key: 'your-xai-api-key')

# Chat completions
result = client.create(messages: [{ role: 'user', content: 'Hello!' }])

# List models
result = client.list

# Retrieve a model
result = client.retrieve(model: 'grok-3')

# Create embeddings
result = client.create(input: 'Hello world')

include Legion::Extensions::Xai::Runners::Chat

result = create(api_key: 'your-key', messages: [{ role: 'user', content: 'Hello!' }])
