How to choose between them
- Prototyping or a tutorial? Pick the one that needs no API key.
- 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.
- Still unsure? Both are free to try: send one request to each and compare the data you get back.
