You can either submit API test requests through the user interface form or trigger the EthicalCheck API using tools like cURL or Postman. To input your request, you will need a public-facing OpenAPI Specification URL, an authentication token that remains valid for a minimum of 10 minutes, an active license key, and your email address. The EthicalCheck engine autonomously generates and executes tailored security tests for your APIs based on the OWASP API Top 10 list, effectively filtering out false positives from the outcomes while producing a customized report that is easily digestible for developers, which is then sent directly to your email. As noted by Gartner, APIs represent the most common target for attacks, with hackers and automated bots exploiting vulnerabilities that have led to significant security breaches in numerous organizations. This system ensures that you only see genuine vulnerabilities, as false positives are systematically excluded from the results. Furthermore, you can produce high-quality penetration testing reports suitable for enterprise use, allowing you to share them confidently with developers, customers, partners, and compliance teams alike. Utilizing EthicalCheck can be likened to conducting a private bug-bounty program that enhances your security posture effectively. By opting for EthicalCheck, you are taking a proactive step in safeguarding your API infrastructure.

Go REST is a versatile platform designed for testing and prototyping APIs that supports both GraphQL and RESTful formats, providing users with realistic fake data that mimics real responses, and is accessible around the clock through public endpoints for various entities such as users, posts, comments, and todos. This platform offers the flexibility of multiple API versions along with comprehensive search capabilities across all fields, pagination options (including page and per_page), and includes rate-limiting headers and response format negotiation to optimize performance. It adheres to standard HTTP methods, while any requests that modify data necessitate an access token, which can be provided via an HTTP Bearer token or as a query parameter. Additionally, nested resource capabilities allow for the retrieval of interconnected data, including user-specific posts, comments on posts, and todos created by users, ensuring that developers can easily access relevant information. The platform also features request and response logging, customizable rate limits, and daily data resets to maintain a pristine testing environment, facilitating a smooth development experience. Furthermore, users can take advantage of a dedicated GraphQL endpoint located at /public/v2/graphql, which enables schema-driven queries and mutations for enhanced data manipulation options.
