Pink Agentic AI Payments (by PinkWallet): lets Claude, ChatGPT, Cursor pay vendor invoices within company spending rules (budgets, caps, allow-lists, human approval). Sandbox preview, test money.
Quietforge x402 Tools is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.
What it does
Free tools: x402 endpoint directory + probe, on-chain x402 demand signal, sudoku, API pricing.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http quietforge-x402-tools-mcp https://qf-api.quietforge-studio.workers.dev/mcp
# 2 — ask your agent for something these tools do
# x402_search, x402_service, x402_index_stats and 4 more
Quietforge x402 Tools costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.
Collected from a public index. Nobody has claimed this account, so nothing here was written by its author — claim it if it is yours.
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http quietforge-x402-tools-mcp https://qf-api.quietforge-studio.workers.dev/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
7 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

Use this to find a pay-per-call x402 API for a given task, network or price cap before calling it (mostly USDC on Base; check each row's network and asset, some are testnet or other assets). Searches 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,
| Parameter | Type | Required | Notes |
|---|---|---|---|
| q | string | no | Case-insensitive substring matched against the resource URL, description and service name; omit for no text filter. |
| network | string | no | CAIP-2 network id to filter on, e.g. eip155:8453 (Base mainnet); omit for all networks. |
| alive | boolean | no | true = answered its paid route on our last probe; false = did not; omit for both. |
| max_price_usd | number | no | Only endpoints priced at or below this USD amount per call; omit for any price. |
| source | string | no | Listing source: cdp (Coinbase CDP bazaar), payai (PayAI discovery) or quietforge (our own endpoints); omit for all sources. |
| limit | integer | no | Page size, 1-100; out-of-range values are clamped. |
| offset | integer | no | Rows to skip for paging; negative is treated as 0. |
Use this to check whether one endpoint from x402_search is reliable enough to pay: its record plus its last 20 health probes (status code, latency, alive) and uptime across them.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| id | string | yes | Service id exactly as returned by x402_search. |
Use this to see how much this index covers (it is a subset of the x402 market, not all of it) and to sanity-check x402_search coverage before relying on it. Summary of the index: totals, how many endpoints answered on the last probe, counts per network and per source, and when the crawl ran.
No parameter schema on file.
Use this to answer "is anyone actually paying for x402 APIs today" with settled on-chain numbers instead of listings. 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-o

Use this to check a URL you are about to pay (or one you operate) for a well-formed x402 challenge before sending funds; a challenge is no guarantee the service delivers. Makes ONE live unpaid request to a public http(s) URL and reports 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
| Parameter | Type | Required | Notes |
|---|---|---|---|
| url | string | yes | Absolute http(s) URL to probe, max 2048 chars; public hosts only. |
| method | string | no | HTTP method. GET unless the URL is already in the index with a different listed method (then that method is allowed). |
Use this when a user wants a sudoku to play or print, or an app needs a verified puzzle at a named difficulty. Generates 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. 2
| Parameter | Type | Required | Notes |
|---|---|---|---|
| level | string | no | Difficulty by solving technique: easy, medium, hard or expert. |
| seed | integer | no | Integer 1-2147483647 for a reproducible puzzle; omit for a random one. |
Price-check Quietforge's paid x402 HTTP routes before paying (free read-only list, not tools here): convert docx, xlsx, pptx, csv to pdf; PDF text; URL/HTML to PNG; sudoku books; manuscript typesetting; crosswords; family trees from GEDCOM; dataset quality audits; x402 index API. USD prices, pay-to address, how an x402 client pays.

- Every tool — any call limit is its publisher’s, not ours
- No card, and mcprush charges nothing for it
- Runs at its publisher’s own address — this marketplace is not in the path
- Nothing to cap, because mcprush bills nothing
What counts against your monthly calls
| Tool | Unit | Calls used | Out of the allowance |
|---|
Nothing here is billable: mcprush charges nothing to install Quietforge x402 Tools or to call it, at any volume.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is an address its publisher runs, and you connect to it directly — this marketplace is not in the path. The scanner reads packages and public source, and an address is neither. So there is no grade — not a withheld one, an unmeasured one.
Release history
This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 1.3.0.
No release note was published with this version.
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Any signed-in account that does not publish Quietforge x402 Tools can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
