GET /mcp
open
Everything for one coin in one call: price, funding and open interest, order book, liquidations, whale orders and news. Costs USD 0.005 per call, paid with x402 (USDC on Base); calls that fail are not charged.
Verdict: not verified by an unpaid GET. 200: serves without a payment challenge. This says nothing about whether the route works when called as declared.
