Computer Vision. A free machine learning API by clarifai.com.

Strengths

AI model hub with inference API for NLP, computer vision, and audio.

We’re on a journey to advance and democratize artificial intelligence through open source and open science.

Strengths

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.
Still unsure? Both are free to try: send one request to each and compare the data you get back.

Both require authentication (OAuth and apiKey).

Hugging Face API supports CORS, so front-end JavaScript can call it directly. Call the other from a server.
