API Security Monitoring
Monitor API exposure and security configuration across your domains
APIs are increasingly targeted by attackers. EdgeDNS helps you discover exposed API endpoints, validate security configurations, and monitor for misconfigurations that could lead to data breaches.
The Challenge
Organizations often lack visibility into their API attack surface. Shadow APIs, misconfigured CORS policies, missing authentication, and exposed documentation create security risks. Manual auditing cannot keep pace with the rapid deployment of new APIs.
The Solution
Use EdgeDNS to automatically discover API endpoints through OpenAPI detection, audit CORS configurations, verify security headers on API endpoints, and monitor for exposed API documentation that could aid attackers.
Endpoints Used
Combine these EdgeDNS endpoints to build this solution.
/v1/domain/openapiTry in PlaygroundOpenAPI Detection: Discover exposed OpenAPI/Swagger documentation
/v1/domain/api-corsTry in PlaygroundCORS Check: Audit CORS policy configuration
/v1/domain/api-versionTry in PlaygroundAPI Version Detection: Identify API versioning patterns
/v1/security/headersTry in PlaygroundSecurity Headers: Verify security headers on API endpoints
Results You Can Achieve
Discover undocumented API endpoints
OpenAPI / spec mismatch detection surfaces shadow endpoints that escaped the published contract.
CORS and rate-limit posture in one scan
Common API misconfigurations validated against OWASP API Top 10 categories.
Continuous scan history per endpoint
Track per-endpoint security posture over time so regressions are visible at deploy boundaries.
Code Example
Audit API security configuration
async function auditApiSecurity(apiDomain) {
const headers = { 'Authorization': 'Bearer YOUR_API_KEY' };
const [openapi, cors, secHeaders] = await Promise.all([
fetch(`https://api.edgedns.dev/v1/domain/openapi?domain=${apiDomain}`, { headers }),
fetch(`https://api.edgedns.dev/v1/domain/api-cors?domain=${apiDomain}`, { headers }),
fetch(`https://api.edgedns.dev/v1/security/headers?url=https://${apiDomain}`, { headers }),
].map(p => p.then(r => r.json())));
const issues = [];
// Check for exposed documentation
if (openapi.data.exposed) {
issues.push('OpenAPI documentation publicly accessible');
}
// Check CORS configuration
if (cors.data.allows_credentials && cors.data.allows_any_origin) {
issues.push('CRITICAL: CORS allows credentials with wildcard origin');
}
return { domain: apiDomain, issues, riskLevel: issues.length > 2 ? 'high' : 'medium' };
