​
Email Validation

This endpoint validates a single email address using the Enrichley API and returns validation and enrichment data.
  • Method: POST
  • Path: /validate-single-email
  • Auth: X-Api-Key header
The request body accepts a single field: 
{
  "email": "jane.doe@example.com"
}
A typical response includes both a JSON body and useful rate-limit / credit headers. For example: 
{
  "email": "jane.doe@example.com",
  "valid": true,
  "result": "catch_all_validated",
  "mx_domain": "example.com",
  "email_type": "business",
  "mx_provider": "example",
  "credits_consumed": true,
  "mx_secure_email_gateway": true
}
And response headers such as:
  • x-ratelimit-limit
  • x-ratelimit-remaining
  • x-ratelimit-reset
  • x-credits-remaining
The OpenAPI specification models this endpoint so the API playground in these docs can be used to send real requests by providing your X-Api-Key.
