  "method": "tools/call",

Input Schema

Name	Required	Description	Default
`id`	Yes	Channel URL, @handle or UC… id
`payment`	No	Optional. Your x402 payment proof for this exact call — the PAYMENT-SIGNATURE value produced by settling this route's 402 challenge (USDC on Base, Polygon or Solana), or an MPP 'Authorization: Payment ...' value. Omit on a first call: the tool then returns the live 402 challenge to pay against. This server relays your proof upstream and retries; it never creates or settles payments itself.
