Add Live AI API Pricing Badges to Your README

Show current AI API costs in your GitHub README, documentation, or blog with a single line of markdown. Free, auto-updating SVG badges for 34 models.

Live badges — these update automatically when prices change:

Why Pricing Badges?

If you're building with AI APIs, your README probably mentions which models you use. But pricing changes fast — GPT-5 launched at different prices than GPT-4o, DeepSeek V4 undercut everyone, and providers adjust pricing regularly.

A live pricing badge keeps your documentation accurate without manual updates. When a provider changes their prices, your badge reflects it automatically.

One Line of Markdown

Add a pricing badge to any GitHub README, GitLab docs, or markdown file:

[![GPT-5 Pricing](https://getapipulse.com/api/badge?model=openai-gpt5)](https://getapipulse.com)

That's it. The badge shows the model name and current input/output pricing per 1M tokens. Clicking it takes visitors to APIpulse for full details.

## Supported Models
[![GPT-5](https://getapipulse.com/api/badge?model=openai-gpt5)](https://getapipulse.com)

Programmatic Access

Need the badge data as JSON for your own tools? Use the format parameter:

# Get embed code as JSON
curl "https://getapipulse.com/api/badge?model=openai-gpt5&format=json"

# Response:
{
  "model": "GPT-5",
  "provider": "OpenAI",
  "pricing": { "input_per_1m": 1.25, "output_per_1m": 10.00 },
  "badge_url": "https://getapipulse.com/api/badge?model=openai-gpt5",
  "embed": {
    "markdown": "[![GPT-5 Pricing](https://getapipulse.com/api/badge?model=openai-gpt5)](https://getapipulse.com)",
    "html": "<a href=\"https://getapipulse.com\"><img src=\"...\"></a>"
  }
}

You can also get just the markdown (format=md) or just the URL (format=url).

How It Works

The badge endpoint is a Vercel Serverless Function that:

1. Looks up the model's current pricing from our database
2. Generates an SVG badge with the model name and prices
3. Returns it as an image/svg+xml response
4. Caches for 24 hours (badges update daily)

The badge colors match each provider's brand — green for OpenAI, orange for Anthropic, blue for Google, etc.

Use Cases

• Open-source AI projects — Show which models your tool supports with current pricing
• API wrapper libraries — Display cost info for each supported provider
• Documentation sites — Keep pricing accurate without manual updates
• Blog posts — Add visual pricing context to comparison articles
• Internal wikis — Help your team track which models you're using and their costs

Full API

The badge endpoint is part of the APIpulse LLM Pricing API — a free, no-auth-required API for AI pricing data. Other endpoints include:

• /api/pricing — Get all 34 models with pricing data
