Is Twilio API free?

Twilio offers a free trial that allows developers to explore and test its APIs without immediate financial commitment. This trial includes a starting credit of $15.50, enabling you to experiment with various services such as SMS, voice, and email. Additionally, during the trial, you can send up to 100 emails per day through the Twilio SendGrid Email API.

After the trial period, Twilio operates on a pay-as-you-go pricing model, meaning you pay only for the services you use. For instance, sending or receiving an SMS in the United States starts at 0.0079 per message**, and making outbound voice calls begins at **0.014 per minute.

This flexible pricing structure allows you to scale your usage according to your project's needs, ensuring cost-effectiveness as your application grows.
