  SoundStat uses a single prepaid, usage-based pricing model rather than fixed
  monthly subscription tiers. Registration is free and yields an API key. Three
  recommendation endpoints - similar tracks, feature-target, and mixed multi-seed
  - are documented as callable for free. Billing applies to unique track analysis:
  you pay only the first time a given track is analyzed, and the per-track price
  drops as your monthly analyzed-track volume increases. Funds are added to a
  prepaid balance via Stripe and are non-refundable. The price points below are
  taken from the SoundStat terms page and are denominated in euros; verify current
  rates during reconciliation.
notes: >-
  Prices are per unique track analyzed per month, in EUR, and step down by volume
  band. Already-analyzed tracks are served from the corpus without re-charging.
  Confirm live pricing, the exact set of free endpoints, and any registration
  quota at soundstat.info before relying on these figures.

    Free account created on registration. Grants an API key and unrestricted

    incurred until a unique (not-yet-analyzed) track is requested.
