About Meta Model API

Meta Model API is Meta's developer platform for its Muse Spark models. Muse Spark accepts text, images, PDFs, video, and audio as input, making it a good fit for multimodal chat and document analysis.

The API uses pay-as-you-go pricing and is drop-in compatible with the OpenAI SDK, so it works with any OpenAI-compatible client. The same console includes chat and image playgrounds, usage tracking, and billing.

Step by step guide to use Meta API Key to chat with AI

I. Get Your Meta API Key

First, you'll need to obtain an API key from Meta. This key allows you to access their AI models directly and pay only for what you use.

Visit Meta's API console
Sign up or log in to your account
Navigate to the API keys section
Generate a new API key (copy it immediately as some providers only show it once)
Save your API key in a secure password manager or encrypted note

Sometimes, this provider will require you to add a payment method to your account before you can use your API key to chat with AI. So, to avoid any hiccups, make sure you've got a payment method set up and ready to go!

Important: Keep your API key secure and never share it publicly. Store it safely as you'll need it to connect with TypingMind.

II. Connect Your Meta API Key on TypingMind

Once you have your Meta API key, connecting it to TypingMind to chat with AI is straightforward:

Option 1: Use the built-in Meta provider (recommended)

The quickest way. TypingMind already has Meta set up, so you only need to add your API key.

Open TypingMind and click "Models" in the left sidebar.
Search for Meta.
Click the settings (gear) button next to Meta.
Paste your API key and save.

Option 2: Add the model manually

If you can't find the provider or model ID in the official list, you can add the model manually:

Open the Models page
Open TypingMind, click "Models" in the left sidebar, then click "Add custom model" in the top right corner.
Enter the model details
Keep "Create Manually" selected and fill in the model details:
Name: muse-spark-1.3 via Meta (or your preferred name)
Model ID: muse-spark-1.3 for example (check Meta model list)
Context Length: Enter the model's context window (e.g., 1048576 for muse-spark-1.3)
Set up authentication
In the "Authentication" tab, set the connection details:
API Type: OpenAI Responses API
Endpoint URL: https://api.meta.ai/v1/responses
Authentication Type: API Key via HTTP Header
Header Key: Authorization
Header Value: Bearer <META_MODEL_API_KEY>
Add pricing (optional)
Open the "Pricing" tab and enter the model's input, output, and cache prices per 1M tokens so TypingMind can estimate your usage costs.
Check the capabilities
In the "Capabilities" tab, keep "Auto check capabilities on save" on so TypingMind detects supported features like plugins, image input, and thinking, or enable them manually.
Test and save
Click "Test & Save" to verify the connection and add the model.
