How to choose between them

  • Prototyping or a tutorial? Pick the one that needs no API key (neither does, so compare their free tiers).
  • Calling from a web page? You need CORS. Otherwise route requests through your own server or a serverless function.
  • Going to production? Favour HTTPS, a strong uptime record and a provider with clear rate limits and terms. Check each API's docs before you commit.
