Your APIs have a risk score.
You just don't know it yet.Scan any API for OWASP Top 10, prompt injection, and Web3 vulnerabilities. Security score in 60 seconds.
Start Free ScanEvery company that builds software runs APIs. Most have no idea which ones are exposed, what data they leak, or how an attacker sees them. middleBrick is a black-box API security scanner that analyzes endpoints across 15 security categories — OWASP API Top 10, LLM prompt injection, and Web3 JSON-RPC — and assigns a quantified risk score with actionable remediation priorities. No agents, no SDK, no config. Results in under 60 seconds.

LLM & AI Endpoint Security
The only self-service scanner with active adversarial probing for AI endpoints. We test your LLM APIs against prompt injection, jailbreaks, encoding bypasses, data exfiltration, and cost exploitation attacks. Three scan tiers from quick validation to deep adversarial testing.
GraphQL Attack Detection
Introspection abuse, query depth attacks, batch query exploitation, alias abuse, and field suggestion disclosure. Active probing, not just schema analysis.
90%+ detection rateBlockchain RPC Security
Detects exposed admin/debug/miner RPC modules, wallet-draining CORS, chain ID mismatches, leaked Alchemy/Infura keys, and DeFi oracle manipulation surfaces. Ethereum, Solana, and Cosmos.
6 protocols14 Parallel Security Checks
Authentication bypass, IDOR, BFLA, SSRF, data exposure, rate limiting, mass assignment, encryption, inventory management, Web3, and DeFi. Every check runs simultaneously.

What types of APIs can middleBrick scan?
REST, GraphQL, and AI/LLM endpoints. We support both traditional HTTP APIs and AI-powered endpoints with specialized prompt injection and data leak detection.
How does the risk scoring work?
We analyze authentication mechanisms, input validation, data exposure patterns, rate limiting, and AI-specific attack vectors. Each dimension gets a sub-score that rolls up into an overall risk rating.
Does middleBrick sit inline with my API traffic?
No. middleBrick sends lightweight, read-only requests to your API. It never sits inline with your traffic or blocks requests. Scanning is asynchronous and non-destructive, so there's zero latency impact on your production traffic.
How long does a scan take?
Most scans complete in under 5 minutes. Continuous monitoring runs on a configurable schedule with near real-time alerting.
Can I integrate middleBrick into my CI/CD pipeline?
Yes. All plans include CI/CD pass/fail gates via CLI and GitHub Action. Startup and Enterprise plans add configurable score thresholds.
Does middleBrick detect prompt injection in AI and LLM endpoints?
Yes. middleBrick runs 18 adversarial probes against LLM endpoints across three scan tiers. It tests for system prompt extraction, jailbreak attacks, encoding bypasses, few-shot poisoning, tool abuse, and PII extraction. It also detects system prompt leakage, model information disclosure, and unauthenticated inference endpoints.
Can middleBrick scan Web3 and blockchain RPC endpoints?
Yes. middleBrick detects and scans Ethereum, Solana, and Cosmos JSON-RPC endpoints. It checks for exposed privileged RPC modules, wallet-draining CORS configurations, chain identity mismatches, leaked provider API keys, and DeFi-specific risks like unauthenticated price oracles and missing slippage protection.
What compliance frameworks does middleBrick support?
middleBrick maps findings to PCI-DSS 4.0, SOC 2 Type II, HIPAA, and OWASP API Security Top 10 2023. Pro plans and above include branded PDF compliance reports with framework-specific remediation guidance.
