Common questions

Is HTTP Headers Analyzer API safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.1.0) reached the registry 6 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

HTTP Headers Analyzer API

Analyze HTTP response headers -- security score, HSTS/CSP check, server detection, caching config. Score 0-100. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.

Part of the klymax402 marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.

Quickstart -- MCP

Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):

"mcpServers": { "http-headers": { "url": "https://http-headers.api.klymax402.com/mcp" } } }

Quickstart -- HTTP (x402)

curl -X POST "https://http-headers.api.klymax402.com/api/analyze" \

-H "Content-Type: application/json" \ -d '{"url":"https://example.com"}'

-> 402 Payment Required, with an x402 payment challenge in the response body

Any x402-aware client (@x402/fetch, x402-agent-tools, ATXP) handles the 402 -> sign -> retry cycle automatically.

Tools

Tool	Method	Path	Price	Description
`network_analyze_headers`	POST	`/api/analyze`	$0.003	Analyze HTTP response headers for a URL

`network_analyze_headers`

When to use: security audits, DevOps monitoring, compliance checks, and verifying proper header configuration after deployment.
