Data & Trading

An API response and a trade preview can look precise without answering the same question. This collection connects data engineering with execution context. The API guide examines stable identifiers, timestamps, precision, error handling, and missing values. The trading-mechanics guide separates liquidity, volume, price impact, slippage, and explicit fees. Read them together to understand why a reference price must not be presented as a guaranteed execution result, and why a newly received response can still contain an old observation.

For a developer, start by writing the meaning of each field before designing the interface. For a reader evaluating a quote, start with the asset, pair, venue, size, and time. Preserve uncertainty in both cases. A missing price is not zero; an execution estimate is not completed activity. The API resource page includes a downloadable static reference and a working local request, but it does not offer a live market service. These articles describe practical boundaries without suggesting a trading strategy, provider subscription, or automatic rule for making an investment decision.
