Nice work! I recently built a similar page, https://letscooktime.com , might be good to compare notes. On integrating with recipe APIs, you can scrape recipe structured metadata. Most web sites use the google structured data, you can query for a script tag with type ld+json and find the structured data. See more information here: https://developers.google.com/search/docs/advanced/structure...

Goals are a little bit different though, designed to be a personal catalog.
