Embed API Subscription Plan
Overview
The Embed API Billing Plan is designed for businesses and developers who want to integrate PostNitro’s social media content generation capabilities directly into their applications via API. This plan provides a credit-based system for generating social media posts at scale.
You can manage your subscription through our Embed API billing page .
API access is not available on the free plan, and there is no free API tier. Calls need a paid PostNitro plan with the Embed API add-on, or a Plus plan that includes API credits. Without either, the API returns 402 (see Authentication). The MCP server, CLI and the Claude and ChatGPT connectors run on the same credits, so the same applies to them.

Credit System
Credit Allocation
- Base unit: 250 credits per plan multiplier
- Plan multiplier range: 1-100 (configurable)
- Maximum credits: 25,000 credits per month (100 × 250)
Credit Consumption
User-Provided Content
- Cost: 1 credit per slide/image
- Use case: When you provide your own text and content
- Example: Creating a 5-slide carousel with your content = 5 credits
Editing a Post
- Cost: 1 credit per slide sent, as for user-provided content
- Use case: When you edit a post made through the API
- Example: Editing a carousel down to 4 slides = 4 credits. The post’s earlier credits aren’t charged again
AI-Generated Content
- Monthly Plan: 2x more credits than user-provided content
- Use case: When you want AI to generate text and content
- Example:
- Monthly: 5-slide AI-generated carousel = 10 credits
Video Voiceover
- Cost: no API credits. A voiceover is charged from the plan’s AI tokens, as the editor’s voiceover is: the tokens the AI used to write the script, plus 5,000 tokens per minute of recorded audio
- Use case: When a video post asks for
videoSettings.voiceover, or you edit a narrated video - Example: A 5-slide video with 27.1 seconds of narration took 2,866 AI tokens. Its API credits are its slides’ alone: 5 credits imported, 10 generated by AI
- When the AI tokens are used up: the video is still made, without narration. See When it can’t be made
