API security scanning for solo founders
As a solo founder, you need security insight without a dedicated team. This scanner operates as a self-service tool, accepting a URL and returning a risk score with prioritized findings. It performs black-box testing, requiring no agents, SDKs, or code access, and supports any language, framework, or cloud environment. Scans complete in under a minute using read-only methods, providing a practical starting point for assessing API posture without operational disruption.
Detection coverage aligned to industry standards
The scanner covers 12 categories aligned to the OWASP API Top 10 (2023), including authentication bypass, JWT misconfigurations, broken object level authorization, privilege escalation, and data exposure. It also maps findings to PCI-DSS 4.0 and SOC 2 Type II, validating controls relevant to those frameworks. Additional checks include CORS misconfigurations, unsafe HTTP methods, debug endpoints, SSRF indicators, and LLM-specific adversarial probes across multiple scan tiers.
- Authentication — multi-method bypass, JWT alg=none, expired tokens, missing claims, sensitive data in claims.
- BOLA / IDOR — sequential ID enumeration and active adjacent-ID probing.
- Data Exposure — PII patterns such as email, Luhn-validated card numbers, context-aware SSN, and API key formats.
- LLM Security — 18 adversarial probes covering prompt extraction, jailbreaks, and token smuggling.
OpenAPI analysis and authenticated scanning
The tool parses OpenAPI 3.0, 3.1, and Swagger 2.0 documents with recursive $ref resolution, cross-referencing spec definitions against runtime behavior. This highlights undefined security schemes, deprecated operations, and missing pagination. For authenticated scans, Bearer tokens, API keys, Basic auth, and cookies are supported after domain verification via DNS TXT or HTTP well-known file. Only a restricted allowlist of headers is forwarded to limit credential exposure.

The platform provides multiple interfaces to fit a solo workflow. The web dashboard centralizes scans, score trends, and downloadable compliance PDFs. The CLI enables quick checks from your terminal, while the GitHub Action can gate CI/CD pipelines based on score thresholds. An MCP server allows scans from AI coding assistants, and a programmable API supports custom integrations. Continuous monitoring options on higher tiers include scheduled rescans, diff detection, and HMAC-SHA256 signed webhooks.

This scanner does not fix, patch, or block issues; it detects and reports with remediation guidance. It does not perform active SQL injection or command injection testing, nor does it detect business logic vulnerabilities, which require domain context. Private IPs, localhost, and cloud metadata endpoints are blocked at multiple layers. Customer data is deletable on demand and purged within 30 days of cancellation, and it is never sold or used for model training.
