  Signeasy does not publish fixed numeric per-second or per-minute request-rate
  limits for the v3 API. Consumption is governed primarily by plan volume - the
  number of legally binding eSignature requests (envelopes) included per month -
  and by a Fair Usage policy for high-volume users. Documented hard constraints
  are structural: a maximum of 45 signers per signature request, a maximum
  document size of 40 MB, and a maximum number of apps per plan (3 on the free
  Starter tier, 10 on Intermediate/Advanced). Webhook delivery has its own
  retry/backoff behavior on the receiver side.
notes: >-
  Numeric API request-rate limits are not documented as of the review date.
  Verify current Fair Usage thresholds, any per-endpoint throttling, and overage
  behavior with Signeasy during reconciliation. Third-party summaries mention
  overage above ~10,000 envelopes/month; treat as unconfirmed.

policies:
- name: Fair Usage
  description: A Fair Usage policy applies restrictions to high-volume users beyond plan allowances.
- name: Webhook Retry
  description: >-
    Webhook events are processed asynchronously (order not guaranteed). Any 3xx,
    4xx, or 5xx response from the receiver is a failure; Signeasy retries with
    exponential backoff for 24 hours, then disables the webhook with an email
    alert until it is fixed and re-enabled.
- name: Backoff Strategy
  description: Clients should implement exponential backoff with jitter and honor Retry-After on 429 responses.
