Sentiment Analysis API - AI-Powered Text Analysis

Analyze text sentiment using AI. Detect positive, negative, neutral tones with emotion detection, confidence scores, and key phrase extraction.

BYOK (Bring Your Own Key) -- you provide your own API credentials.

Before You Start

This actor requires your own API credentials to fetch real data.

Where to get your key: Your OpenAI API key for AI-powered sentiment analysis. If not provided, uses rule-based analysis.

You can test with Demo Mode first (free, no key needed) to see the output format before committing.

Troubleshooting

"API key is required"

You have Demo Mode turned off but didn't provide an API key. Either:

• Turn Demo Mode on to test with sample data
• Add your API key in the input

"API error 403" or "Unauthorized"

Your API key is invalid, expired, or doesn't have access to this specific API endpoint. Double-check your key and account permissions.

"API error 429" or "Rate limit"

Too many requests. Wait a minute and try again, or reduce the number of items per run.

No results or empty dataset

Check the run log for error messages. Common causes:

• Invalid input format (check the examples above)
• API key without proper permissions
• The target data doesn't exist or is too small to track

How do I test without an API key?

Enable Demo Mode in the input. This returns realistic sample data so you can verify the output format works for your workflow.
