x402

x402_demand

Market-level demand signal for the x402 ecosystem, verified against on-chain USDC settlement on Base rather than self-reported call counts: how many seller addresses were paid in the last 24h, total USD settled, and the distribution of sellers by payment count. Free and aggregate-only; the per-seller breakdown (distinct payers per address — what separates a service with real customers from an operator paying themselves) is the paid GET /v1/x402/demand route. Refuses to answer rather than serve a stale snapshot.

x402_index_stats

Summary of the x402 service index: totals, how many endpoints answered on the last probe, counts per network and per source, and when the crawl ran.

x402_probe

Make ONE live unpaid request to a public http(s) URL and report whether it is an x402 endpoint: status code, latency, alive flag, whether a PAYMENT-REQUIRED challenge came back and the parsed USD price. GET only, except that a URL already in the index is probed with its listed method. Public hosts only (redirects re-checked), delisted hosts never contacted, results cached 60 s, 3 probes per host per 5 min and 30 per minute overall.

x402_search

Search a health-probed directory of live x402 pay-per-call HTTP endpoints on Base, Solana and other networks (x402_index_stats gives the current count). Returns id, resource URL, method, network, USD price, description, 30-day call/payer counts and our own uptime/probe data. Data is re-crawled a few times a day, not real-time.

x402_service

One endpoint from the x402 service index by id (from x402_search), with its last 20 health probes (status code, latency, alive) and uptime across them.

quietforge

quietforge_pricing

List Quietforge's paid x402 routes (document conversion, PDF text extraction, URL/HTML → PNG/JPEG/PDF rendering, sudoku books, manuscript typesetting, x402 index JSON API) with USD prices, the pay-to address and network, and how an x402 client pays. Free, read-only.

sudoku

sudoku_puzzle

Generate ONE sudoku puzzle with a unique solution, 180-degree symmetry, graded by the solving techniques it needs (easy | medium | hard | expert). Returns 81-char puzzle and solution strings (row by row, 0 = empty), given count and technique list. Deterministic when a seed is supplied. 20 per minute shared by all clients.

Quietforge x402 Tools — questions

Answers built from our own checks of this server.

What can Quietforge x402 Tools do?

It exposes 7 tools, read directly from the server on our last check. Among them: quietforge_pricing, sudoku_puzzle, x402_demand, x402_index_stats, x402_probe, x402_search and 1 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Quietforge x402 Tools working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 57 of 59 checks got a reply (96.6%), average response time 536 ms. The bar chart above shows every period we have measured.

Is Quietforge x402 Tools still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect Quietforge x402 Tools?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Quietforge x402 Tools need an API key?

No. Quietforge x402 Tools completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Quietforge x402 Tools?

It answers our handshake in 536 ms on average, which is faster than 28% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
