description: Paid service calls have no per-caller rate limit. Wallet challenges have bounded capacity and can return
  429. Request size limits apply. We never log your IP; only technical metadata such as User-Agent and Referer.
  Limits are signalled by HTTP 429 only — no RateLimit-*/X-RateLimit-*/Retry-After headers are documented anywhere
  in the contract.
