  tZERO publishes no rate limits for either REST API. Neither OpenAPI declares a 429 response,
  neither contract mentions rate limiting, and no RateLimit-*, X-RateLimit-* or Retry-After header
  is documented. A live anonymous request to https://api.t0direct.com/api/v1/webhooks/events on
  2026-09-01 returned 401 with no rate-limit headers in the response. An agent integrating with
  tZERO has no published runtime signal to back off against; limits, if any, are set contractually.
