Get a spotify URI or track from an ISRC

[s-sx9fpd4i_hq]

Hi All,

I have a big bunch of ISRC codes and would like to get their associated Spotify tracks. From the docs, it looks like the only way to access a resource from the ISRC is by using it as a search query, and with the number of codes I have I'd hit the request rate limit pretty quickly. 

Does anyone know of another way of doing this or any good workarounds?

Cheers
