description: >-
  Signaturely does not publish a fixed numeric per-second or per-minute request
  rate limit for its API. In practice, usage is governed by a monthly quota of API
  signature requests tied to your API plan - 50/month on Gold, 150/month on
  Platinum, and 500/month on Titanium - plus a plan-based cap on the number of
  templates (5, 25, and unlimited respectively). Read and management operations
  (listing documents, templates, folders, team members, subscribing webhooks) are
  not the metered unit; the billable/limited action is sending a signature request.
notes: >-
  No explicit HTTP request-rate ceiling (requests per second/minute) is documented
  as of the review date. The effective limit is the monthly API signature-request
  quota per plan. Verify current quotas on the Signaturely API pricing page during
  reconciliation.
