  note: Both surfaces are real and they are not the same product. The remote Streamable HTTP endpoint
    exposes 18 tools, needs no install and never sees the caller's key - payment happens per tools/call
    via an x402 challenge returned inside the result. The stdio npm package exposes 14 tools and requires
    a funded EVM private key in ANCHOR_WALLET_PRIVATE_KEY inside the local process. The provider documents
    this trade-off explicitly in llms.txt.

  paid_methods:
  - tools/call
  flow: A tools/call without payment returns a RESULT (not a JSON-RPC error) with isError true and the
    x402 challenge in structuredContent.accepts. The caller signs one of the offered rails and retries
    the identical tools/call with a PAYMENT-SIGNATURE header. The provider states the challenge is delivered
    as a result deliberately, because a JSON-RPC error would be swallowed by the client before the model
    saw it.
