# ai-to-openai-hono

An adapter to add OpenAI compatibility to your Hono app using the Vercel AI SDK.

## Install

https://jsr.io/@ns/ai-to-openai-hono

## Usage

```ts

import { Hono } from 'hono'

import { createOpenAIHono } from '@ns/ai-to-openai-hono'

import { anthropic } from 'npm:@ai-sdk/anthropic' // or your favorite provider

const app = new Hono() // Your existing or new Hono app

// Mount the OpenAI-compatible endpoint

app.route(

  '/my-ai-endpoint',

  createOpenAIHono({

    languageModels: {

      'claude-3.7-sonnet': anthropic('claude-3-7-sonnet-20250219'), // Map model names to Vercel AI SDK instances

      // ... add more models here

    },

    // Optional: Add API key verification

    verifyAPIKey(key) {

      // In production, compare against securely stored keys (e.g., environment variables)

      return key === 'this-is-super-secret-key'

    },

  }),

)

export default app

```

Next, run your Hono server. The OpenAI-compatible endpoint will then be

available.

```ts

import { OpenAI } from 'openai'

const openai = new OpenAI({

  baseURL: 'http://localhost:8080/my-ai-endpoint',

  apiKey: 'this-is-super-secret-key',

})

const completion = await openai.chat.completions.create({

  model: 'claude-3.7-sonnet',

  // ...

})

console.log(completion.choices[0].message.content)

```
