Batch API

Classify multiple emails in a single request using the batch endpoint. This is more efficient than making individual requests and counts as one request per email in the batch.

Request

POST /v1/classify/batch

Body

{
  "emails": [
    "[email protected]",
    "[email protected]",
    "[email protected]"
  ]
}

curl -X POST "https://emailkind.com/v1/classify/batch" \
  -H "Authorization: Bearer sk_live_YOUR_KEY" \

        "is_custom_domain": false
      },
      "confidence": 0.99
    }
  ]
}

The batch endpoint accepts up to 100 emails per request. Each email in the batch counts as one request toward your quota.

Company enrichment

Add the enrich=true query parameter to any classify request to receive additional company information alongside the standard classification.

Request

curl -H "Authorization: Bearer sk_live_YOUR_KEY" \
  "https://emailkind.com/v1/[email protected]&enrich=true"

Response

{
  "success": true,
  "request_id": "req_abc123",
  "email": "[email protected]",
  "domain": "stripe.com",
  "provider": {
    "id": "google_workspace",
    "name": "Google Workspace",
    "type": "business"
  },
  "classification": {
    "is_business": true,
    "is_free": false,
    "is_disposable": false,
    "is_education": false,
    "is_custom_domain": true
  },
  "company": {
    "name": "Stripe",
    "domain": "stripe.com",
    "industry": "Financial Technology",
    "size": "1001-5000",
    "country": "US"
  },
  "mx": [
    "smtp.google.com",
    "smtp2.google.com"
  ],
  "confidence": 0.98,
  "cached": false
}

The company field is only returned when enrich=true is set and the domain belongs to a recognized business. For personal, disposable, or unknown domains, the company field will be null.

Company fields

| Field | Type | Description | |---|---|---| | company.name | string | Company legal or trading name | | company.domain | string | Primary company domain | | company.industry | string | Industry classification | | company.size | string | Employee count range (e.g. 1-10, 11-50, 51-200, 201-500, 501-1000, 1001-5000, 5001+) | | company.country | string | Two-letter ISO country code |

Enrichment adds latency to requests. Standard requests resolve in under 50ms; enriched requests may take up to 500ms. See the SLA for details.
