name: CoinNudge Data API Rate Limits
description: >-
  Published request-rate and daily data-transfer limits for the CoinNudge Data
  API, by plan. Runtime rate-limit response headers are not documented and could
  not be observed on live requests (all endpoints return 401 without a key).
limit_count: 3
exhaustion_status: 429
response_headers:
  documented: false
  note: >-
    No X-RateLimit-* / RateLimit-* / Retry-After headers are documented; they
    could not be observed because every endpoint requires an authenticated key.
limits:
  - scope: per-account
    plan: Free
    requests_per_minute: 60
    daily_data_transfer: null
    api_keys: 1
  - scope: per-account
    plan: Researcher
    requests_per_minute: 60
    daily_data_transfer: 1 GiB/day
    api_keys: 1
  - scope: per-account
    plan: Research Desk
    requests_per_minute: 300
    daily_data_transfer: 5 GiB/day
    api_keys: 5 (limit shared across the account)
notes: >-
  On exhaustion the API returns 429 (rate limit or daily quota exceeded).
  Oversized single queries may return 413. Clients should respect each dataset's
  declared refresh_seconds rather than polling continuously.
