description: >-
  Signzy does not publish specific public rate-limit numbers. Throughput is
  governed per-account by the commercial agreement and access token, and the
  preproduction / sandbox environment carries lower quotas than production.
  Access tokens issued by /api/customers/login are short-lived (a `ttl` in
  seconds) and must be refreshed. Specific per-endpoint request-per-minute
  values are not documented publicly and are not reconciled here.
notes: >-
  Confirm per-account and per-endpoint limits with Signzy during onboarding;
  no public rate-limit table was found on 2026-07-17.
