Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/hyperliquid/market?coin=BTC&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum, Monad, World Chain or Tempo) and retries.
