description: >-
  Backendless does not throttle API call volume - all Cloud plans advertise
  unlimited API calls per month. Instead, capacity is governed by per-plan
  resource caps (file storage, number of data tables, and concurrent real-time
  connections) and, on the Scale plan, by daily billing tiers keyed to peak API
  requests per minute. Standard request constraints apply, such as a maximum
  page size of 100 objects on data retrieval. Specific account-level concurrency
  and per-endpoint values are not reconciled in this artifact.
notes: >-
  Confirm current real-time connection caps, data-table caps, and the Scale plan
  peak requests-per-minute tier table on the Backendless Cloud pricing page
  during reconciliation. Data find operations are capped at a page size of 100.

  throttled: 429
limits:
- name: API Calls Per Month
  scope: account
  metric: requests
  limit: unlimited (un-throttled on all Cloud plans)
  notes: API call volume is not throttled; Scale plan bills via daily peak-RPM tiers.
- name: Real-Time Connections
  scope: account
  metric: connections
  limit: 5 (Free) / 1000 (Scale); expandable via function packs
  notes: Concurrent Socket.IO real-time connections; raise with the real-time function pack.
- name: Data Tables
  scope: account
  metric: tables
  limit: 20 (Free) / 100 (Scale)
  notes: Maximum number of database tables per application.
- name: File Storage
  scope: account
  metric: gigabytes
  limit: 1 GB (Free) / 10 GB (Scale); expandable via function packs
  notes: Hosted file repository capacity.
- name: Data Page Size
  scope: request
  metric: objects
  limit: 100
  notes: Maximum objects returned per data find request via pageSize.
- name: Scale Peak RPM Tier
  scope: account
  metric: requests_per_minute
  limit: tiered (billing, not a hard cap)
  notes: Daily Scale billing tier is set by the day's peak API requests per minute.
policies:
- name: Un-Throttled API Calls
  description: All Backendless Cloud plans provide unlimited, un-throttled API calls; capacity scales with plan resources and Scale billing tiers.
- name: Backoff Strategy
