Chalk Labs
Need help deploying api-security?
Chalk Labs sets up agents like this inside real teams: connected to your tools, tested on your data, with a human in the loop where it matters.
Install
Works with Claude Code, Claude apps, Codex, Cursor, Gemini CLI, GitHub Copilot, VS Code, OpenCode, Goose, Windsurf. Read the repository before you give any tool access to your data.
npx agentmarket install skill/gohilrajbha0312-api-security
Asks which of your tools to add it to (Claude Code, Codex, Cursor, VS Code, Windsurf, Gemini CLI, Claude Desktop) and shows the change first. See https://agentmart.dev/cli.
Get the weekly diff
The weekly diff: one email a week with new agent tools, notable updates and grade changes, plus security alerts for tools you follow. Double opt-in, one-click unsubscribe.

# API Security Test API endpoints for security vulnerabilities across REST, GraphQL, WebSocket, and LLM-integrated APIs. ## Techniques | Type | Key Vectors | |------|-------------| | **GraphQL** | Introspection, batching attacks, nested query DoS, field suggestion | | **REST API** | BOLA/IDOR, mass assignment, rate limiting, auth bypass, versioning | | **WebSocket** | Cross-site hijacking, message manipulation, auth flaws | | **Web-LLM** | Prompt injection via API, excessive agency, data exfiltration | ## Workflow 1. Discover API endpoints and documentation (Swagger, GraphQL schema) 2. Map authentication and authorization mechanisms 3. Test per API type using appropriate techniques 4. Validate data exposure and access control flaws 5. Capture evidence with HTTP request/response logs ## Reference - `reference/graphql*.md` - GraphQL attack techniques and labs - `reference/scenarios/rest/*.md` - REST API security testing (BOLA/BOPLA, mass assignment, SSPP, content-type confusion) - `reference/websockets*.md` - WebSocket vulnerability testing - `reference/web-llm*.md` - Web-LLM attack techniques and labs
