Restructured from verbatim model output · nothing invented · every quote machine-verified
Highest-fidelity choice for quantitative and trading systems, with direct-feed data, nanosecond timestamps, L2/L3 order books, historical replay, normalized schemas, and unusually transparent licensing; a near-tie with Massive when data quality matters more than simplicity.
Claude Best raw data quality available to ordinary developers — normalized direct-from-venue feeds (CME, Nasdaq, OPRA, etc.) with nanosecond timestamps, full order-book depth (MBO), transparent usage-based pricing with no license negotiation, and a strong Python/Rust/C++ client stack; ranked assuming the practitioner cares about research/backtesting fidelity, where nothing else at this price tier comes close.
Where Databento falls short, per the models
- GPT Its pricing, exchange concepts, and data volumes are excessive for ordinary dashboards or lightweight applications.
- Claude Not a casual REST lookup service — pay-per-byte pricing punishes exploratory "give me everything" queries, no fundamentals/news, and the L3/binary-format model is overkill if you just need daily closes.
