Start with a free GET request. Each tool has a defined input and scope.
A response received now can contain older observations. Read dates, units and source status.
Keep limitations and source notices with the answer. Missing data should stay missing.

EARLY DEVELOPER PREVIEW
Try one tool in your own workflow. Tell us what helped, what was missing and where you got stuck. We're learning from real use cases.
Try a free request →Crypto and macro tools query sources on demand with short caches. Source observations can be older than the request. WhaleScope is a fixed historical sample; Audit calculates from your supplied snapshot.
Six tools are free, including Market Input Check and Execution Cost Compare. Only Orderbook Audit uses 0.01 test USDC on Base Sepolia; mainnet is not enabled.
This preview has no latency guarantee and never executes trades. The free host can take about a minute to wake up. Use it for exploratory workflows that can inspect dates and handle missing data.
