How to request access

Email support@lyrcs.ai with the following information:

Company name

Your organisation’s full legal name and any relevant brand names.

Use case

What you’re building — e.g. “deliver time-synced lyrics to DSPs for Indian language catalog” or “lyric display feature for streaming app”.

Expected monthly volume

Estimated number of tracks per month. This helps us provision the right rate limits for your account.

Languages

Which languages you primarily work with. Indian language catalogs receive enhanced processing.
We’ll respond within 2 business days with your API key and webhook secret.

​
What you’ll receive

  • An API key in the format lyrcs_sk_live_... — used as the Bearer token in the Authorization header
  • A webhook secret — used to verify HMAC-SHA256 signatures on webhook deliveries
Both are scoped to your organisation. All jobs, usage, and webhooks are isolated to your org.
Keep your API key and webhook secret secure. Do not commit them to source control or expose them in client-side code. If you believe a key has been compromised, contact support@lyrcs.ai immediately.
