Transformed our NLP pipeline

The sentiment analysis is remarkably accurate across English, Spanish, and Korean. Emotion detection adds a layer our previous solution didn't have. Worth every cent.

Clean API, great results

The structured output with confidence scores makes it easy to build reliable downstream logic. We use this for email validation in our onboarding flow and it catches 99% of bad addresses.

Good but could be faster

Works well for most use cases but latency spikes on very large inputs. The 200ms timeout is tight for documents over 2MB. Hope to see optimizations in the next version.

Reliable CSV handling

Handles edge cases that broke our previous parser — quoted fields, embedded newlines, mixed encodings. The schema detection is a nice bonus. Free tier is generous.

Solid performance, good value

At $0.0001/call this is a steal. We process millions of JSON documents monthly and the cost is negligible. Would give 5 stars if streaming support was added.
