Assess newly discovered API issues quickly
When bug bounty findings appear, you need a fast, reliable way to understand risk without adding infrastructure. Submit the API endpoint or host URL to a black-box scanner and receive a risk score from A to F with prioritized findings within a minute. The scan uses read-only methods such as GET and HEAD, plus text-only POST for LLM probes, so no destructive payloads are sent.
Map findings to recognized security frameworks
Each finding maps to OWASP API Top 10 (2023), and where applicable aligns with PCI-DSS 4.0 and SOC 2 Type II controls. For other regulations, the tool helps you prepare for audits by surfacing findings relevant to frameworks such as HIPAA, GDPR, ISO 27001, NIST, CCPA, and related standards. It does not certify compliance, replace an auditor, or guarantee adherence to any regulatory requirement.
Cover the OWASP API Top 10 with targeted detections
The scanner evaluates 12 categories including Authentication bypass, JWT misconfigurations such as alg=none or expired tokens, BOLA and IDOR via sequential ID enumeration, BFLA and privilege escalation through admin endpoint probing, Property Authorization over-exposure, Input Validation issues like CORS wildcard and dangerous HTTP methods, Rate Limiting and oversized responses, Data Exposure including PII patterns and API key formats, Encryption and HSTS misconfigurations, SSRF via URL-accepting parameters, Inventory issues like missing versioning, and LLM/AI Security through adversarial probes across Quick, Standard, and Deep tiers.
Use OpenAPI analysis to cross-check runtime behavior
It parses OpenAPI 3.0, 3.1, and Swagger 2.0 with recursive $ref resolution, then cross-references spec definitions against runtime findings. This highlights undefined security schemes, sensitive fields, deprecated operations, and missing pagination, giving you a discrepancy view that supports audit evidence and helps prioritize fixes.
Configure authenticated scans and safe integrations
Authenticated scanning supports Bearer, API key, Basic auth, and Cookie. Domain verification is enforced through DNS TXT records or an HTTP well-known file so only the domain owner can scan with credentials. The scanner forwards a limited header allowlist including Authorization, X-API-Key, Cookie, and X-Custom-* headers. Use the CLI with middlebrick scan <url>, integrate via the GitHub Action as a CI/CD gate, or connect through the MCP Server and API client for custom workflows.
