You can also use this API to broadcast transactions.

Rate Limits

Up to 3 requests/sec is free. Need more? Please create a free account on the TAAL Platformand view the available subscription plans there. We offer packages with 10 requests/sec, 20 requests/sec, or custom Enterprise plans.

Once you get your API key from the Platform, here is a usage example:
