Question: Can you recommend an API that retrieves metadata from URLs, such as title, description, and image?

If you're looking for an API that pulls metadata out of URLs, URL Meta is a good choice. It provides a wide range of APIs to pull metadata like title, description, image, favicon and logo out of URLs and domains. The service also includes a Screenshot API for high-resolution PNG images and a DNS API for all standard record types. You can choose from free and premium plans, with 500 requests per month on the free plan.

Another interesting API is SingleAPI, which uses GPT-4 technology to convert any website into an API in a matter of seconds. It scrapes data out of websites and returns it in JSON format, supporting a variety of data formats and real-time webhooks. The system also includes automated proxy rotation and 24/7 uptime. Pricing ranges from a free Hobby plan to a Professional plan at $75 per month, so SingleAPI should be able to handle whatever you throw at it.

If you're looking for something more specific metadata retrieval, CaptionAI could be what you're after. Although it's primarily designed to generate image captions, descriptions and tags, it can also be used to improve web accessibility, SEO and content discovery. It's a good tool for e-commerce sites, social media and blogs, and has a variety of pricing plans to match your needs.
