    RPC access is authenticated with an API key created at
    https://app.conduit.xyz/nodes. The key is appended to the RPC URL of the
    target rollup (path segment), e.g.
    https://rpc.<chain>.conduit.xyz/<API_KEY>. A single key works across all
    public and private endpoints scoped to it. Keys can be restricted by domain,
    IP, and contract-deployer address, and can be regenerated or deleted.

  scoping: per-network (a key scoped to one network returns -32403 "unauthorized
    rpc key" on another)
  restrictions: [domain, ip-address, contract-deployer-address]

  type: http
  scheme: payment-channel
  description: >-
    The agentic gateway at https://mpp.conduit.xyz authenticates via Machine
    Payments Protocol (MPP) sessions instead of API keys. The client opens a
    USDC payment channel on Tempo and sends signed off-chain vouchers with each
    request. First unpaid request returns 402 Payment Required with a
    'WWW-Authenticate: Payment' header. Cost is $0.00005 per JSON-RPC call.

  note: Public RPC endpoints are usable without a key at a reduced 200 CU/s throughput tier.
