Who This API Is For

Developers building registration or onboarding flows

• CRM and Sales Ops teams performing bulk list cleaning

• Marketing teams improving deliverability and reducing bounces

• SaaS platforms validating users at scale

• Data engineering pipelines requiring automated email checks

Send a request with an email address or file.

• The API performs:

  • Syntax check

  • Domain and DNS lookup

  • MX record detection

  • SMTP mailbox verification

  • Disposable / role-based / risk analysis

• A structured response returns:

  • status (VALID, INVALID, DO_NOT_MAIL, etc.)

In this case, we are building a normal React component, but adding a control to it, to enable setting of the Text property from the canvas. To set this up we use the addPropertyControls API as seen above.

Authentication

All API requests require a Bearer token.

Authorization: Bearer <API_KEY

These annotations let Framer know what size your component should be inserted into the canvas when fixed sizing is enabled. In this case, it will insert with a width of 200px and a height of 200px.
