  Sinay sells access through its Developers Platform as a marketplace of REST
  APIs metered by monthly API calls / API units (credits). Published tiers are a
  free plan for getting started, a higher-volume Pro plan, and a custom
  Enterprise plan; a no-credit-card free trial is also offered. Each API reports
  its own consumption through a /usages or /consumption endpoint
  (consumedApiUnits, credit periods). Exact per-call prices and currency are not
  reconciled here - the figures below reflect publicly described allowances and
  should be confirmed on the Sinay Developers Platform pricing page.
notes: >-
  Call/credit allowances are drawn from public descriptions of Sinay's Developers
  Platform (free plan ~500 calls/month across ETA, CO2, Port Congestion, Noise;
  Pro ~10,000 calls/month; Enterprise custom; free trial ~100 calls/month, no
  credit card). Per-API credit weighting differs by product (some calls consume
  more than one API unit). Verify current tiers, prices, and per-endpoint credit
  costs on the Developers Platform during reconciliation.
