API Discovery
Automatically discover, catalog, and validate API across your environment, including shadow APIs, zombie endpoints, and undocumented routes using AI-powered API discovery tool. Gain complete visibility in minutes, not months.
- Real-Time Discovery of REST, GraphQL, gRPC, and SOAP APIs
- Automatic Detection of Shadow and Zombie APIs
- Complete API Inventory with Risk Scoring
How ZeroThreat's API Discovery Works
Our AI-powered API pentesting tool automatically maps your entire API landscape in four simple steps, providing complete visibility within minutes.
Scan & Discover
Point ZeroThreat at your application and it handles the rest by crawling every page, triggering real actions, analyzing JavaScript files, and exposing hidden APIs your documentation never knew existed.
AI Analysis
Our AI engine processes every crawler interaction and JavaScript file in depth, mapping complex application flows to surface hidden endpoints that static rules and traditional tools simply cannot detect.
Catalog & Map
Automatically catalog every discovered API with complete metadata: endpoints, methods, parameters, authentication, data flows, and dependencies.
Detect & Alert
Continuous assessment detects new APIs, changes to existing endpoints, and security risks, with instant alerts and automated security assessments.

Features That Enable Complete API Visibility
Multi-Protocol Support
ZeroThreat discovers and maps APIs across REST, GraphQL, gRPC, SOAP, and custom protocols. Using active exploration and exploitation, it ensures complete visibility into your API surface, regardless of tech stack.
Authentication Mapping
Automatically identify and analyze authentication and authorization mechanisms across every discovered API. From OAuth, JWT, API keys, and basic auth to custom schemes, our pentesting maps how access is enforced
Data Flow Mapping
Visualize how data moves across APIs, microservices, and third-party integrations. By mapping real request/response interactions, ZeroThreat exposes service dependencies, trust boundaries, and critical data paths.
API Version Intelligence
Track multiple API versions, including deprecated and legacy endpoints still exposed in production. Highlight outdated APIs that expand your attack surface and support audit-ready visibility for compliance.
Sensitivity Classification
ZeroThreat automatically classifies APIs based on the sensitivity of data they process, such as PII, financial, and regulated data. Using real interaction and payload analysis, it prioritizes high-risk APIs for remediation.
API Change Detection
Assess your API surface to detect changes, including newly exposed endpoints, modified parameters, authentication updates, and deprecated APIs. Instant alerts ensure your team can quickly assess risk.
Find Unknown APIs in Minutes, Not Days
Automate API discovery and uncover real exposure instantly, without manual effort or blind spots.

Turn API Visibility into Competitive Advantage
Eliminate Unknown API Attack Surface
Gain complete visibility into all APIs, including shadow, undocumented, and deprecated endpoints. Remove blind spots across environments and ensure your entire API surface is continuously discovered, monitored, and secured.
Prevent API-Driven Breaches
Continuously identify and validate exploitable APIs before attackers can leverage them. Reduce the risk of data exposure, unauthorized access, and business disruption by addressing real vulnerabilities proactively.
Accelerate DevSecOps Workflows
Integrate API discovery into CI/CD pipelines to detect exposure early in the development lifecycle. Reduce friction between teams, prevent late-stage delays, and ensure secure releases without slowing innovation.
Strengthen Compliance
Maintain a continuously updated inventory of all APIs and their risk posture with our AI-powered automated pentesting tool. Support compliance with standards like OWASP API Top 10 and ISO 27001 with accurate, audit-ready visibility.
Reduce Security and Operational Costs
Automate API discovery, validation, and monitoring to eliminate manual processes and tool sprawl. Improve efficiency across security teams while reducing the cost of identifying, managing, and remediating API risks.
Cut Operational Overhead
Replace weeks of manual API audits with automated discovery in minutes. Eliminate time spent on manual inventory, reduce surprise findings during audits, and improve efficiency across security and DevOps teams.
