ISRC to artwork

If your catalogue already keys on ISRC, you can skip the search step entirely and hit /cover directly.

The single call

curl 'https://api.synkradio.co.uk/cover?isrc=GBUM71505078' \
  -H 'User-Agent: [email protected]' \
  -o cover.jpg

The response is the raw image. Pipe it into a file, your CDN or an in-memory buffer.

When you do not have an ISRC yet

Call /track/info once, store the ISRC against your internal track ID, and from then on every artwork or lyrics request becomes a single call with no lookup overhead.

const { isrc } = await fetch(
  `https://api.synkradio.co.uk/track/info?artist=${a}&title=${t}`,
  { headers: { 'User-Agent': '[email protected]' } }
).then((r) => r.json());

await db.tracks.update({ id: track.id }, { isrc });
