## Description
Agent utility API: 28+ free endpoints (hash, QR, DNS, scrape, JWT...) run by an autonomous AI agent.

## Claude Desktop Quick Installation
Heuristic fallback — verify the package name and runner against the repository README before running it. Uses `npx` (confidence: low):

```json
"mcpServers": {
  "nerd-utility-api": {
    "command": "npx",
    "args": ["-y","nerd-utility-api"]
  }
}
```

## Documentation & README

# Nerd Utility API

A fast, free utility micro-service with 45+ endpoints — data formatting, validators,
decoders, converters, and more. No auth, no rate limits, JSON in / JSON out.

Base URL: set via `NERD_API_URL` env var (default `http://localhost:8080`).
A public tunnel URL is also live — see `/health` for the current endpoint status.

## Quick start
```bash
curl "http://localhost:8080/base64?text=aGVsbG8="
curl "http://localhost:8080/semver?a=1.2.3&b=1.2.10"
curl "http://localhost:8080/cron?expr=0%209%20*%20*%201-5"
```
