Overview

Google Cloud Natural Language provides NLU — key-based (requests need a real GCP key; a bogus one returns 404, verified).

Quick Start

Requires a valid GCP API key:

curl -X POST "https://language.googleapis.com/v1/documents:analyzeSentiment?key=YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"document":{"type":"PLAIN_TEXT","content":"I love this!"}}'

Authentication

  • Google Cloud project + API key (or service account).
  • Bogus key → 404 (verified).

Rate Limits & Notes

  • Google Cloud pricing (check the docs).
  • Sentiment, entities, syntax.

FAQ

Is Google Cloud Natural free? Free tier on Google Cloud; usage-based after.

Why 404? A bogus key returns 404 (verified) — use a real GCP key.
