Tiingo
What ChatGPT, Claude, Gemini & Grok actually say · July 2026
The verdict
Tiingo appears in 1 AI-ranked category.
Outstanding value for end-of-day and IEX-sourced intraday US equity data — famously clean, survivorship-bias-aware historical prices back decades, generous cheap tiers (~$10–30/mo), plus news and crypto endpoints; the quiet favorite of quant hobbyists and backtesters.
GPT Exceptional value for research and EOD workflows, offering clean adjusted history, broad securities coverage, long price histories, news, and predictable flat-rate individual pricing.
Where Tiingo falls short, per the models
- GPT Internal-use licensing and less mature consolidated real-time equities support make it unsuitable for many customer-facing live-data products.
- Claude Intraday/real-time comes from IEX's exchange feed only (~2–3% of volume), so quotes can diverge from consolidated tape — not suitable for live trading signals; near-tie with Finnhub below.
