Developer API Documentation

This page lists only the analysis and dataset GET endpoints currently implemented for public access. Optional fields may be omitted when the stored source data is unavailable.

Availability

The endpoints below do not require an API key. Dedicated paid tiers, bandwidth guarantees, and historical-trend APIs are not currently offered. Avoid excessive polling and handle 404, 503, and missing fields. Dataset downloads contain the latest 100 records under CC BY-NC 4.0.

Metric semantics

unusualReviewSignal (the dataset keeps the legacy field name fraudScore) is a 0–100 signal for unusual posting patterns. It is not the percentage of fraudulent reviews and does not prove fraud or rating manipulation. reliabilityScore is a separately stored composite review metric; it is not 100 − unusualReviewSignal.
