  Per-account rolling 1-minute window — every live key on an account shares one budget, so adding
  keys does not raise the ceiling. Test keys (api_test_) count in a separate bucket with their own
  stricter limit.
limits:
- scope: per-account
  plan: Free
  window: 1 minute (rolling)
  limit: 10
  note: Results additionally capped to the first 5 pages (page 6+ returns 400 ER0173); articles delayed 12 hours.
- scope: per-account
  plan: Starter / Basic / Professional
  window: 1 minute (rolling)
  limit: 50
  note: The three tiers share the same throughput — they differ in quota and features, not requests per minute.
- scope: per-account
  plan: Corporate
  window: 1 minute (rolling)
  limit: 200
- scope: per-endpoint
  endpoint: /v1/fact-check
  window: 1 minute
  limit: 10
  note: Separate, stricter limit because every request runs language-model inference; not available on Free.
- scope: per-account
  kind: concurrent SSE connections
  limit_by_plan: {Free: 0, Starter: 2, Basic: 2, Professional: 10, Corporate: 50}
  note: Exceeding it returns 429 ER0360.
- scope: per-request
  kind: max per_page
  limit_by_plan: {Free: 10, Starter: 50, Basic: 200, Professional: 250, Corporate: 250}
  note: Requesting more returns 400 ER0171 naming the plan ceiling; the default page size clamps to the ceiling.
- scope: per-query
  kind: title-search published_at window
  limit: 31 days
  note: >-
    Every plan, every endpoint (incl. exports, SSE, WebSocket). Wider range returns 400 ER0110;
    a title search with no dates searches the last 31 days and flags it with warning ER0366 and
    an x-query-window-clamped: 31 header.
- scope: per-account
  kind: pay-as-you-go monthly spending limit
  limit: user-configured (cents, UTC calendar month)
  note: When reached, balance-billed requests return 402 ER0177 until the month resets.
