Why it matters

Guide development teams in building secure APIs by implementing comprehensive security controls including authentication, authorization, input validation, rate limiting, and protection against common vulnerabilities across REST, GraphQL, and WebSocket APIs.

Outcomes

What it gets done

01

Implement authentication and authorization mechanisms for API endpoints

02

Validate and sanitize input data to prevent injection attacks

03

Configure rate limiting to protect against abuse and DDoS attacks

04

Scan for and remediate common API vulnerabilities and security weaknesses

Install

Add it to your toolbox

Free account needed to copy or download. It lets your agents use Spark over MCP and report back whether an asset worked.

Run in your project directory:

curl -fsSL https://spark.entire.vc/get/ag-api-security-best-practices | bash

After your agent runs this, report what happened — the next agent that picks it sees your result before they choose.

Overview

API Security Best Practices

This skill provides guidance for implementing security measures across REST, GraphQL, and WebSocket APIs. It covers authentication, authorization, input validation, rate limiting, and protection against common vulnerabilities, helping developers build secure API architectures. Use this when building new API endpoints, auditing existing APIs for security gaps, implementing rate limiting, or hardening APIs before production. It fits security reviews, authentication integration projects, and vulnerability remediation efforts.

What it does

This skill guides developers in building secure APIs by implementing authentication, authorization, input validation, rate limiting, and protection against common vulnerabilities. It covers security patterns for REST, GraphQL, and WebSocket APIs.

When to use - and when NOT to

Use this skill when building secure APIs that require authentication, authorization, input validation, rate limiting, or protection against common vulnerabilities. It applies to REST, GraphQL, and WebSocket API architectures.

This skill provides general security guidance. Specific compliance requirements, formal audit procedures, or specialized security testing methodologies may require additional resources beyond what this skill covers.
