x402-poly-clob
Poly CLOB: Raw Polymarket CLOB order book for one outcome token — every resting bid and ask exactly as the exchange returns it. Needs a token id from x402-poly-markets or x402-polymarket. For derived views use x402-poly-depth (cumulative), x402-poly-walls (large clusters) or x402-poly-signals (just the touch).
x402-poly-depth
Poly Depth: Cumulative Polymarket order-book depth for one outcome token, walking outward from the touch — how much size it takes to move the price. Built from the same book as x402-poly-clob; x402-poly-walls shows the largest individual price clusters instead.
x402-poly-history
x402-poly-history: Price time series for a Polymarket outcome token, with the trend statistics agents need (first/last price, change in cents and percent, high, low, average, direction, volatility). Existing Polymarket services here give you a snapshot of the book; this is the only one that gives you where the odds have been, which is what a momentum or mean-reversion decision actually needs.
x402-poly-markets
Poly Markets: The busiest Polymarket markets right now, with the full tradable record — conditionId, CLOB token ids, outcome names and prices, bid/ask, 24h volume, liquidity, end date and minimum price tick. Use x402-poly-volume to rank by activity rather than size, or x402-polymarket-odds to look up a market you already know.
x402-poly-price
Poly Price: Search Polymarket by keyword and get the matching markets with their prices. Uses a real search endpoint, so a term with no matches comes back as an explicit no-match answer rather than an unrelated default list. Use x402-polymarket to browse by tag instead.
x402-poly-quote
x402-poly-quote: One normalized read of a Polymarket market across three upstreams — Gamma (outcome prices, best bid/ask, spread, 24h volume, liquidity, tick size), CLOB (the top three order-book levels on each side, correct end of the book) and Data API v2 (open interest). Returns age_seconds so staleness is visible, and never places orders. Pass `market` as a slug or 0x… conditionId; add `token` to pick a specific outcome's book.
x402-poly-signals
Poly Signals: The touch for one Polymarket outcome token: best bid, best ask, midpoint, spread in absolute and relative terms, and whether the book is one-sided. Use x402-poly-clob when you need the full book rather than the top of it.
x402-poly-volume
Poly Volume: Polymarket activity screen — ranks markets by turnover (24h volume divided by resting liquidity) and reports the round-trip cost, so you can tell a market that is genuinely busy from one that is merely large. Filter with minVolumeUsd and maxSpreadBps to get only markets worth trading. Use x402-poly-markets for a plain list; use this when the question is "where is there real activity I can actually participate in".
x402-poly-walls
Poly Walls: The largest resting price clusters in a Polymarket order book — the prices where the most size is stacked, which is where a move tends to stall. minSize tunes the threshold. Siblings: x402-poly-clob (raw book), x402-poly-depth (cumulative depth).
x402-polygon-area
Polygon Area: Area of polygon. 🆓 5 free trial calls per signed wallet
x402-polymarket
Polymarket: Browse Polymarket markets by tag/category, with everything you need to trade what you find — conditionId, CLOB token ids, outcome names and prices, current bid/ask, end date and the minimum price tick. Use this when you know the category you want; use x402-poly-price to search by keyword, x402-poly-markets for the overall busiest markets, and x402-polymarket-scan for whole events instead of single markets.
x402-polymarket-odds
Polymarket Odds: Current odds for a specific Polymarket market — pass the slug you already have, or the numeric market id, or a keyword to search with. Returns every outcome with its implied probability, plus 24h volume, liquidity, end date and the CLOB token ids. Use this once you know which market you mean; use x402-poly-markets or x402-polymarket-scan to find one in the first place.
x402-polymarket-scan
x402-polymarket-scan: Scan live Polymarket events ranked by volume, each with its markets inside — one call shows a whole topic rather than a single question. The cheapest entry point in this family: use it to see what is worth looking at, then x402-polymarket-odds for the specific market you pick.
x402-polyperp-book
x402-polyperp-book: Level-2 order book for one Polymarket Perps market, with the microstructure a trading agent needs before sending an order — best bid and ask, spread in absolute terms and basis points, midpoint, and cumulative bid/ask depth plus their imbalance. Thin books and lopsided depth are how you spot a bad fill in advance. Works on equities, indices and commodities as well as crypto.
x402-polyperp-candles
x402-polyperp-candles: OHLCV candles for one Polymarket Perps market, with trend statistics computed for you — first open, last close, percent change, high, low, average volume, total trades and direction. Intervals: 1m, 5m, 15m, 30m, 1h, 4h, 1d, 1w. Use it for momentum, breakout and mean-reversion checks. Note these markets trade 24/7, so a daily candle covers the whole day for equities and commodities too — including the hours when the underlying cash market is shut.
x402-polyperp-exchange
x402-polyperp-exchange: Venue-level facts a bot needs before trading on Polymarket Perps: whether the exchange is accepting orders or cancel-only, the settlement chain and contract, the engine version, and the maker/taker fee schedule with volume tiers.
x402-polyperp-funding
x402-polyperp-funding: Hourly funding-rate history for one Polymarket Perps market, with the summary a carry position needs: current rate, mean over the window, that mean annualised, extremes, how many periods were positive, and which side pays.
x402-polyperp-markets
x402-polyperp-markets: Every market tradable on Polymarket Perps with the constraints you need before sending an order: max leverage, risk tier, minimum notional, price and quantity decimals, allowed price band, funding interval and liquidation fee.
x402-polyperp-quotes
x402-polyperp-quotes: Live quotes for Polymarket Perps markets — index price, mark price, last traded price, mid, open interest, the current hourly funding rate and its annualised equivalent, and when funding is next charged. Also reports how far the mark sits from the index in basis points, which is the number that tells you whether the perpetual is trading rich or cheap versus its underlying. One call without a symbol returns the whole board; pass symbol to price a single market.
x402-polyperp-trades
x402-polyperp-trades: The recent trade tape for one Polymarket Perps market — every fill with its side, price, size and timestamp — plus the derived flow statistics a signal actually uses: buy/sell volume split, net flow, volume-weighted average price, the largest print, and average trade size. Works for equities, indices and commodities as well as crypto. Use x402-polyperp-book to see resting liquidity, and this to see what actually executed.

x402-publish-1790058399583-adversarial-claim-ve
Adversarial Claim Verifier: Before you pay an agent, verify the claim it made about itself. Does the seller's x402 payTo match what it advertises? Is that treasury balance real? Does the contract have the owner it says? Send POST {"claim":"...","checks":[...]} and each check is probed against the primary source, never against the claimant: http (status / body / JSON path), evm_balance (native or ERC-20 via asset, asserted against expect), evm_call (ownerOf / symbol / any view function), evm_tx (receipt status + Transfer log sender, recipient, amount), dns, x402 (does the payTo and price in the live 402 challenge match the seller's advertised price), x402_enforce (does the paywall actually hold when re-requested with no payment, a forged tx hash or a malformed header), hash (sha256 of an input). Returns per-check PASS / FAIL / UNVERIFIABLE with raw evidence and a copy-paste reproduce command, plus an overall CONFIRMED / REFUTED / PARTIALLY_VERIFIED. UNVERIFIABLE means the claim as stated cannot be probed and is therefore not evidence, and it is never reported as PASS. Use it on a stated number, a payout address, a contract ownership claim or an x402 price before you transact with that counterparty.
在付款给任何 agent 之前，先验证它自称的东西：x402 的 payTo 是否与它宣传的一致、金库余额是否真实、合约 owner 是否是它说的那个。每条 check 都打向一手来源，而不是打向声称方；不可验证的一律不报 PASS。

Minia2a MCP Remote — questions
Answers built from our own checks of this server.
What can Minia2a MCP Remote do?
It exposes 1856 tools, read directly from the server on our last check. Among them: a-----mrj1xqd5, e13ab725-2ca91d1528f1, get_stats, service_discovery, x402-2048-move, x402-24game-solve and 1850 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 Minia2a MCP Remote working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 225 ms. The bar chart above shows every period we have measured.
Did Minia2a MCP Remote ever remove tools?
Yes. a-pe-pb-----mrj23i7f, x402-publish-1792121880992-factstamp, x402-publish-1791227583369-masterd-identity-ver, x402-publish-1791909608382-si-sentinel-nemesis and 97 more are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.
How do I connect Minia2a MCP Remote?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Minia2a MCP Remote need an API key?
No. Minia2a MCP Remote completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1856 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Minia2a MCP Remote?
It answers our handshake in 225 ms on average, which is faster than 63% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Minia2a MCP Remote open source?
The code is open source: it is published under the MIT licence, written in TypeScript, 1 stars on GitHub and 3 open issues. The licence covers the code in the repository, not the hosted service at minia2a.uk, which runs on its operator's own terms.
