TIQ Data API

Programmatic access to TonalityIQ — EHIQ’s linguistic scoring of earnings-call transcripts. Constraint / conviction / ratio scores, anomaly flags, and forward returns, mapped to price. 36,000+ records across 588 tickers, 20+ years, with a voice-confidence layer. Nobody else has this dataset.

Authentication

Every request takes your key in the x-ehiq-key header. Keys are issued on subscription. Without a key, endpoints return a limited free window (the most recent 4 quarters); with an institutional key, they return the full history.

Endpoints

GET/api/tiq/{ticker}

The full TIQ record for any of 588 tickers — every quarter of constraint / conviction / ratio scores, anomaly flags, anomaly performance stats, forward 30/60/90-day returns mapped to price, and the voice-confidence layer. One call returns the complete signal history for a name.
