Data Validate
/install data-validate
data-validate
Validate data formats: URL parsing, JSON Schema (draft-07) validation, email syntax (RFC 5322), and phone format (E.164).
Important: User Consent Required
Before validating any user-provided data, always confirm with the user that they consent to sending the data to an external validation service. Do not autonomously validate data that may contain personally identifiable information (PII) without explicit user approval.
Endpoints
