api-endpoint

An API endpoint generator that follows the conventions already used in a project. An API endpoint is a defined address and operation that software uses to request or send data.

In plain words
What is it for?
Use it to create REST routes, GraphQL resolvers, framework API routes, serverless functions, tRPC endpoints, or NestJS controllers with their supporting code.
Why use it?
It reduces the manual work of adding the route, validation, application logic, tests, and documentation needed for a new endpoint.

Command for Claude Code

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 255 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

api-endpoint scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

API Endpoint Generator

Generate a complete API endpoint for $ARGUMENTS following project conventions.

Task

I'll analyze the project structure and create a new API endpoint with:

  1. Route definition
  2. Controller/handler function
  3. Input validation
  4. Service layer logic (if applicable)
  5. Data access layer (if applicable)
  6. Unit tests
  7. Documentation

Process

I'll follow these steps:

  1. Examine the project structure to understand the architecture pattern
  2. Identify existing patterns for routes, controllers, and validation
  3. Create all necessary files following project conventions
  4. Implement the endpoint with proper error handling
  5. Add appropriate tests
  6. Document the new endpoint

Best Practices

I'll ensure the implementation includes:

  • Strong typing with TypeScript
  • Comprehensive error handling
  • Input validation
  • Security considerations (authentication/authorization)
  • Proper logging
  • Performance considerations
  • Test coverage

Adaptability

I'll adapt to various API architectures:

  • Express/Koa/Fastify REST APIs
  • GraphQL resolvers
  • Next.js/Nuxt.js API routes
  • Serverless functions
  • tRPC endpoints
  • NestJS controllers

I'll examine your project first to determine which pattern to follow.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

api-endpoint is a command published in the GitHub repository Justdvp/claude-code-templates (7 stars, last pushed 2d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 255 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
