+# Email Validator API Overview
+
+This document provides a comprehensive overview of the Email Validator API endpoints available through RapidAPI.
+
+## Base URL
+```
+https://email-validator.p.rapidapi.com
+```
+
+## Authentication
+All API requests require the following headers:
+- `X-RapidAPI-Host`: email-validator.p.rapidapi.com
+- `X-RapidAPI-Secret`: Your RapidAPI proxy secret
+
+## Endpoints
+
+### 1. Validate Single Email
+Validates a single email address and returns detailed validation results.
+
+**Endpoint:** `/validate`
+
+**Methods:** GET, POST
+
+#### GET Request

+```
+
+#### POST Request
+```json

+    "email": "[email protected]"
+}
+```

+#### Response
+```json
+{
+    "email": "[email protected]",
+    "validations": {
+        "syntax": true,
+        "domain_exists": true,
+        "mx_records": true,
+        "is_disposable": false,
+        "is_role_based": false
+    },
+    "score": 100,
+    "status": "VALID"
+}
+```
+
+#### Possible Status Values
+- `VALID`: Email is valid and deliverable
+- `PROBABLY_VALID`: Email is probably valid but has some issues
+- `INVALID`: Email has significant validation issues
+- `MISSING_EMAIL`: No email was provided

+
+#### Response

+{
+    "results": [
+        {
+            "email": "[email protected]",
+            "validations": {
+                "syntax": true,
+                "domain_exists": true,
+                "mx_records": true,
+                "is_disposable": false,

+            "score": 100,
+            "status": "VALID"
+        },
+        {
+            "email": "[email protected]",
+            "validations": {
+                "syntax": true,

+            "score": 80,
+            "status": "PROBABLY_VALID"
+        }
+    ]
+}
+```
+
+### 3. Typo Suggestions
+Get suggestions for possible typos in email addresses.
+
+**Endpoint:** `/typo-suggestions`
+
+**Methods:** GET, POST
+
+#### GET Request
+```
+GET /[email protected]
+```
+
+#### POST Request
+```json
+{
+    "email": "[email protected]"
+}
+```
+
+#### Response
+```json
+{
+    "email": "[email protected]",
+    "suggestions": [
+        "[email protected]",
+        "[email protected]"
+    ]
+}
+```
+
+### 4. API Status
+Check the current status and performance metrics of the API.
+
+**Endpoint:** `/status`
+
+**Method:** GET
+
+#### Response
+```json
+{
+    "status": "operational",
+    "uptime": "99.99%",
+    "requests_handled": 1000000,
+    "average_response_time_ms": 150.5
+}
+```
+
+## Error Responses
+When an error occurs, the API will return an error response with an appropriate HTTP status code:
+
+```json
+{
+    "error": "Error message describing what went wrong"
+}
+```
+
+Common HTTP status codes:
+- `400 Bad Request`: Invalid input or missing parameters
+- `401 Unauthorized`: Invalid or missing API key
+- `403 Forbidden`: Exceeded API quota or unauthorized access
+- `429 Too Many Requests`: Rate limit exceeded
+- `500 Internal Server Error`: Server-side error
+
+## Rate Limiting
+The API implements rate limiting based on your RapidAPI subscription plan. When you exceed the rate limit, you'll receive a 429 status code.
+
+## Best Practices
+1. Always check the validation status and score to make decisions
+2. Handle disposable email addresses according to your use case
+3. Implement proper error handling for all possible status codes
+4. Cache validation results when appropriate
+5. Use batch validation for multiple email checks to improve performance
