note: 'All quantified limits below are published verbatim by IMVU in the Resource Limits section of the
  room-scripting documentation. They govern the in-world Lua scripting sandbox, not an HTTP API. IMVU
  publishes NO rate limits for api.imvu.com, and that host returns no RateLimit-*, X-RateLimit-* or
  Retry-After headers on the unauthenticated responses probed on 2026-08-23 — the response headers
  observed were server, date, expires, cache-control, pragma, vary and x-imvu-rnd only.'

- name: lua-sandbox-memory
  surface: IMVU Room Scripting
  scope: per-room
  limit: 10485760
  unit: bytes
  window: n/a
  description: 'Every individual room is limited to approximately 10 megabytes of memory in its Lua
    sandbox, including around 400 kilobytes of overhead.'
- name: cpu-cores

- name: data-module-per-visitor
  surface: IMVU Room Scripting (data.save / data.load)
  scope: per-visitor
  limit: 5120
  unit: bytes
  window: n/a
  description: 'Visitor data has no total limit cap, but a limit of 5 kilobytes per visitor across all
    scopes. These limits are described by IMVU as provisional and subject to change.'
- name: poll-duration

  scope: per-poll
  limit: 1800

unquantified_limits:
- name: outgoing-message-and-invite-throttle
  surface: IMVU Room Scripting
  description: 'Outgoing messages, room invites, and other output to visitors are rate-limited to help
    prevent obstructive amounts of spam; IMVU does not publish the numeric ceiling. Top-level limits are
    also imposed against the script persona in any given room.'
- name: data-module-throughput
  surface: IMVU Room Scripting (data.save / data.load)
  description: 'A throughput limit applies to save/load; saving or loading too quickly starts returning
    error messages. The threshold is not published.'
- name: streaming-media
  surface: IMVU Room Scripting (imvu.control_media)
  description: 'A script can stream in only one room at a time, and IMVU automatically stops the stream
    if the room owner leaves the room.'
data_retention:
  policy: 'IMVU reserves the right to delete stale data; the provisional measure is deleting data that
    has not been READ in at least the past 365 days.'
