Validation Types

Comprehensive validation at every layer of the request

🔑
Header Validation
Validate required headers, API keys, content types, and custom headers.
Authorization Content-Type X-API-Key
📦
Payload Validation
JSON schema validation for request bodies with type checking and constraints.
JSON Schema Size Limits Encoding
🎯
Parameter Validation
Query params, path variables, and form data with type coercion.
Query Params Path Vars Defaults
🛡️
Security Validation
SQL injection, XSS, rate limiting, and malicious pattern detection.
SQL Injection XSS Filter Rate Limit
📝
Schema Validation
OpenAPI/Swagger schema compliance for structured API validation.
OpenAPI 3.0 Swagger 2.0 AsyncAPI
⏱️
Timing Validation
Request timestamps, expiration checks, and replay attack prevention.
Timestamp Expiry Nonce

Validation Examples

Code samples for common validation scenarios

📝 Header Validation JavaScript 
// Validate required headers
const validateHeaders = (req) => {
  const required = ['authorization', 'content-type'];
  
  for (const header of required) {
    if (!req.headers[header]) {
      throw new Error(`Missing: ${header}`);
    }
  }
  
  // Validate content-type
  const contentType = req.headers['content-type'];
  if (!contentType.includes('application/json')) {
    throw new Error(Invalid content type);
  }
};
📦 Payload Schema JSON 
{
  "type": "object",
  "required": ["model", "messages"],
  "properties": {
    "model": {
      "type": "string",
      "enum": ["gpt-4", "gpt-3.5-turbo"]
    },
    "messages": {
      "type": "array",
      "minItems": 1,
      "maxItems": 100
    },
    "temperature": {
      "type": "number",
      "minimum": 0,
      "maximum": 2
    }
  }
}
