description: >-
  Messari documents rate limits per plan tier. Free API tier is approximately 20 requests per
  minute and 1,000 requests per day per IP. Paid Pro and Enterprise tiers raise the per-minute
  cap and lift the daily cap. Throttled requests return HTTP 429 with rate-limit headers.
notes: Free limits widely documented; Pro/Enterprise limits vary by contract.
