description: >-
  A genuine rehearsal environment for the paid operation: the identical x402 feed on Base Sepolia with
  faucet USDC. The provider's words - "The exact same x402 feed, on Base Sepolia instead of Base mainnet.
  Only two things change: network is base-sepolia and the USDC is the testnet token ... Everything else -
  the 402 terms, the EIP-3009 signature, the purr you get back - is identical." Real settlement on the
  test network, no real money. Every value below is copied from the provider; nothing is invented.
