Purpose and scope of pre-funding API hygiene
Before funding or scaling an API program, you need a lightweight, fast assessment of surface risk without intrusive testing. This scanner provides a read-only security overview focused on hygiene and posture. It does not perform intrusive exploitation, active SQL injection, or command injection testing. The workflow supports early-stage due diligence while acknowledging that business logic flaws and blind SSRF require human review.
How the scanner supports pre-funding assessments
The scanner submits only read-only methods (GET and HEAD) plus text-only POST for LLM probes, completing in under a minute. It parses OpenAPI 3.0, 3.1, and Swagger 2.0 with recursive $ref resolution and cross-references spec definitions against runtime behavior. This helps you identify undefined security schemes, deprecated operations, missing pagination, and exposed sensitive fields before committing capital. The tool flags issues aligned to OWASP API Top 10 (2023), PCI-DSS 4.0, and SOC 2 Type II control evidence.
Authentication and authorized scanning requirements
Authenticated scanning is available from the Starter tier and above, supporting Bearer, API key, Basic auth, and Cookie credentials. Domain verification is enforced via DNS TXT record or an HTTP well-known file to ensure only the domain owner can scan with credentials. Header forwarding is limited to Authorization, X-API-Key, Cookie, and X-Custom-* to reduce noise and maintain a controlled read-only footprint.
Risk categories and compliance framing
The scanner evaluates 12 categories relevant to pre-funding hygiene, including Authentication bypass, BOLA/IDOR, BFLA/privilege escalation, property authorization over-exposure, input validation, rate limiting, data exposure, encryption, SSRF, inventory management, unsafe consumption, and LLM/AI security. Findings map directly to OWASP API Top 10 (2023), help you prepare for PCI-DSS 4.0 and SOC 2 Type II, and surface findings relevant to audit evidence for regulatory alignment. Other frameworks are referenced using alignment language only, such as helps you prepare for or aligns with security controls described in.
Operational models and integrations for funding workflows
Use the Web Dashboard to review scans, track score trends, and download branded compliance PDFs. The CLI supports one-command scans with JSON or text output, and the GitHub Action can gate CI/CD when scores drop below a threshold. The MCP Server enables scanning from AI coding assistants, and the API client allows custom integrations. Continuous monitoring (Pro tier) provides scheduled rescans, diff detection, email alerts rate-limited to 1 per hour per API, and HMAC-SHA256 signed webhooks with auto-disable after 5 consecutive failures.
Limitations and next steps
The scanner does not fix, patch, block, or remediate findings; it reports with remediation guidance. It does not detect business logic vulnerabilities, blind SSRF, or perform active injection tests. It is not a replacement for a human pentester in high-stakes audits. If you need deeper assurance, follow up with targeted manual reviews and third-party assessments before funding decisions.
