Hi

Since Customily launched the Spotify Player last year, it has become very popular: customers can search a track and instantly see artist info and album cover art, which significantly improves the purchasing experience.

However, we’re concerned about long-term reliability:

Spotify Web API doesn’t provide a clear “pay-to-scale for guaranteed quota” path, so high-traffic usage can easily hit frequency/stability limits;

Spotify has tightened Development Mode rules and supported endpoints/limitations, and on March 9, 2026 the new restrictions will be migrated to existing Development Mode apps—this may impact the normal operation of the Customily Spotify Player (please evaluate the impact carefully and adapt accordingly):

To reduce future uncertainty (in case Spotify becomes even more restrictive), I suggest the Customily team evaluate and select a paid, scalable music catalog/metadata provider as an optional alternative or fallback (track search → artist/album → cover art), so merchants can rely on a more stable service.

Backup providers (ranked by recommendation priority):

Napster API (high throughput, developer-friendly): documented 500 requests/sec per application

Gracenote / TiVo (enterprise-grade, contract-based stability): documented that limits can be removed after signing a contract for production use

Music Story (clear licensing for media assets + API): cover art / artist images licenses

7digital (catalog + high quality album art, more partner-oriented):

Last.fm (partnership path for higher usage): ToS indicates exceeding limits requires explicit approval and may involve additional terms/fees
