Authentication

All API requests require authentication using an API key. Include your key in the X-API-Key header.

X-API-Key: your_api_key_here

Webhooks

Receive instant notifications when analysis completes. Provide a webhookUrl in your request.

Webhook Payload:

POST https://your-webhook-url.com/endpoint
Content-Type: application/json
X-Ansius-Signature: HMAC-SHA256 signature
X-Ansius-Request-Id: unique-request-id

{
  "requestId": "unique-id",
  "status": "completed",
  "data": {
    "matchScore": 87,
    "maxScore": 100,
    "analysis": { ... },
    "categoryScores": { ... },
    "matches": [ ... ]
  },
  "metadata": {
    "processedAt": "2025-10-17T10:30:45Z",
    "processingTime": 45000,
    "creditsUsed": 1
  }
}

Verify Webhook Signature:

// Node.js example
const crypto = require('crypto');

function verifyWebhook(payload, signature, secret) {
  const expectedSignature = crypto
    .createHmac('sha256', secret)
    .update(JSON.stringify(payload))
    .digest('hex');
  
  return crypto.timingSafeEqual(
    Buffer.from(signature),
    Buffer.from(expectedSignature)
  );
}

Important: Always verify webhook signatures to ensure requests are from Hirewall API.

Rate Limits

Rate limits are customized per partnership. Standard limits:

• 30 requests per minute

Best Practices

• Use webhooks instead of polling for better performance and real-time updates

• Implement idempotency by providing unique requestId values to prevent duplicate processing

• Verify webhook signatures to ensure requests are from Hirewall API

• Handle rate limits gracefully with exponential backoff and retry logic

• Keep API keys secure - never expose them in client-side code or public repositories

• Monitor usage via rate limit headers to optimize request patterns
