openrouter

HTTP Client for the OpenRouter API (https://openrouter.ai)

Installation

1. Add the dependency to your shard.yml:

   dependencies:
     openrouter:
       github: petterthowsen/openrouter
   

2. Run shards install

Usage

require "openrouter"

# create a client instance
client = OpenRouter::Client.new "sk-or-v1-123456789..."

# get available models as an Array of OpenRouter::Model 
models = client.get_models

# get a completion from a single text prompt:
response = client.complete("Hello, how are you?", "mistralai/mistral-7b-instruct:free")

# or use the CompletionRequest class to construct a more complex request with multiple messages:
request = OpenRouter::CompletionRequest.new(
      model: "mistralai/mistral-7b-instruct:free",
      messages: [
        OpenRouter::Message.new(role: OpenRouter::Role::User, content: "If I have 10 apples..."),
        OpenRouter::Message.new(role: OpenRouter::Role::Assistant, content: "You have 10 apples and... ?"),
        OpenRouter::Message.new(role: OpenRouter::Role::User, content: "I eat half of them. How many do I have left?"),
      ]
    )

response = client.complete(request)

Development

Pretty self-explanatory. The main class is the Client in ./src/openrouter/client.cr. It uses the CompletionRequest in ./src/openrouter/types/completion_request.cr and Response in ./src/openrouter/types/response.cr.
