GET /coverage
live
Hyperliquid perps (perpetual futures). What history exists before you pay for it: how many markets we track, which asset classes, and the range covered. The cheap probe that tells an agent whether the paid series is worth buying
Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.
