  No tiers, no subscription, no account, no card. Reads and transaction builders are free; three resources are
  paid per call in USDC over x402 v2 (exact scheme) on Base (eip155:8453) or Polygon (eip155:137), and the Solana
  gas lane in Solana USDC. Protocol fees on the vault itself are charged on-chain, separately from the API.
summary: >-
  Prices below are read from the machine-readable x402 resource catalog (accepts[].amount in USDC-6) and the live
  402 challenges on 2026-09-19, cross-checked against the contract's x-payment blocks and llms.txt. Protocol fees
  come from GET /v1/basket (fees.mintBps 20, fees.mgmtBpsPerYear 90, fees.perfBps 0, minDepositUsdc 1000000).
