Values you fill in

• AGENTPAY_BASE_KEY secret env
  Optional EVM private key for wallet mode: settle paid tools in-place (gasless EIP-3009 on Base). Keyless free-tools mode works without it.
• AGENTPAY_ENABLE_PAID env
  Set to 1 to settle paid tools from the wallet the server mints on first run (fund it with USDC on Base first). Off by default.
• AGENTPAY_MAX_SPEND env
  Hard per-session spend cap in USD when wallet mode is enabled (default 0.10).

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

• session_create

  Open a budget-capped agent session on AgentPay. Pay $0.01 USDC once — get a session_id, budget config, and gateway URL. Enforces a hard max_spend cap across all subsequent tool calls via the AgentPay SDK. The entry point for agents discovering AgentPay on Base Bazaar. Use when: Y

• pre_trade_check

  One-call pre-trade sanity check: 'I want to long $X of SYMBOL — is now sane?' Combines live orderbook slippage at YOUR size, cross-exchange funding (carry cost), open-interest crowding, and contract security (GoPlus) into a single ok/caution/avoid verdict with a per-factor breakd

• verified_route

  Paid buyer-side trust oracle: 'I need X, budget $Y — which x402 tool is real?' Sweeps the WHOLE x402 marketplace across many queries (a single search shows only a slice), collapses sybil/factory clusters (one wallet stamping many fake-distinct listings → one entry), ranks the gen

• funding_spread

  Cross-venue perp funding divergence for one asset — the basis/carry read, not the raw rates. Reads Binance, Bybit, OKX, Gate.io, Bitget, Hyperliquid, dYdX, MEXC and KuCoin in parallel, normalises every rate to a per-8h figure (hourly venues scaled), and returns the spread (max mi

• sbtc_peg

  The sBTC peg as an agent-readable feed — the one dataset only Stacks state can answer. Live sBTC supply (and share of the peg cap), peg-in and peg-out flows for 24h and 7d (sats, counts, unique recipients, net), in-flight bridge requests (pending and accepted deposits with the ol

• token_price

  Get the current USD price of any cryptocurrency token Use when: You need the current USD price, 24h change, or market cap of any cryptocurrency. Not for: you need volume, ATH or a pair quote — token_market_data; a one-call macro + crypto overview — market_snapshot; pool depth or

• gas_tracker

  Get current Ethereum gas prices (slow, standard, fast) Use when: You need to know current Ethereum gas prices before submitting a transaction or estimating costs. Not for: you need gas as part of a broader read — market_snapshot already includes standard gwei; only Ethereum mainn

• yield_scanner

  Find best DeFi yield opportunities across protocols for a given token Use when: You need to find the best yield/APY for a token across DeFi protocols. Not for: you need a protocol's total TVL rather than pool APYs — defi_tvl; risk_level is a heuristic, run token_security on the p

• open_interest

  Get total open interest in perpetual futures for any asset, with 1h and 24h change rates. Pairs with funding_rates to complete the derivatives picture — rising OI with high funding = overcrowded position. Use when: You need to know total open interest in perpetual futures and whe

• orderbook_depth

  Get real bid/ask depth and slippage estimates at $10k, $50k, and $250k notional from Binance, Bybit and OKX. Use before sizing a position to know if you can execute without moving the market. Use when: You need to estimate slippage before executing a large trade. Tells you how mu

• wallet_balance

  Get the token balances for any Ethereum or Stellar wallet address Use when: You need to look up the token holdings of an Ethereum or Stellar wallet address. Not for: you want a token's price or market data rather than one address's holdings — token_price / token_market_data; larg

• fear_greed_index

  Crypto Fear & Greed Index (0=extreme fear, 100=extreme greed) with optional history Use when: You need to gauge overall crypto market sentiment or mood — whether the market is fearful or greedy. Not for: you want token-specific sentiment — crypto_news (per-token headlines) or fun

• crypto_news

  Latest crypto news and community sentiment from r/CryptoCurrency for any token Use when: You need recent news headlines or community sentiment for one or more crypto tokens. Not for: you need general web news or documentation — web_search; a specific article's text — url_reader;

• defi_tvl

  DeFi protocol Total Value Locked from DeFiLlama. Returns top 10 or a specific protocol. Use when: You need the Total Value Locked in a specific DeFi protocol or want to compare the top protocols by TVL. Not for: you want the best yield for a token — yield_scanner; protocol revenu

• token_market_data

  Get market cap, 24h volume, ATH, and price change for any token. Note: does NOT return pool depth or slippage — for pre-trade liquidity estimates, use a dedicated orderbook tool. Use when: You need 24h trading volume, market cap, or all-time high for a token pair on decentralized

• token_security

  Scan any token contract for honeypot, rug pull, and security risks Use when: You need to check if a token contract is safe before trading or investing. Not for: the asset is a native coin (BTC, ETH, SOL) with no contract — nothing to scan; you want liquidity or price — orderbook_

• funding_rates

  Get perpetual futures funding rates across Binance, Bybit, and OKX Use when: You need funding rates to gauge leveraged market sentiment or cost of holding a perp position. Not for: you need open interest or long/short ratio — open_interest; one verdict combining funding, OI, slip

• dune_query

  Run any Dune Analytics query and return live onchain results by query ID. Use fast_only=True for live bots — returns cached result instantly or raises immediately, never blocks. Use when: You need deep onchain analytics from a specific Dune query — protocol revenue, user counts,

• url_reader

  Convert any URL to clean, LLM-ready markdown. Strips ads, nav, and boilerplate — returns just the content. No API key needed. Use when: You need to read the content of a web page or article and get clean, structured text for further processing. Not for: you do not have a URL yet

• web_search

  Search the web and return the top 5 results with their full content as clean markdown. Better than DIY because zero setup and results include page content, not just links. Use when: You need to find current information on any topic — news, documentation, prices, events, or anythi

• market_snapshot

  Fed rate, inflation proxy, S&P 500, BTC, ETH, and gas in one call. Replaces three separate API integrations with a single normalized response — the only tool that gives you macro + crypto in one shot. Use when: You need a combined macro + crypto market overview in one call: S&P 5

• whale_activity

  Detect recent large wallet movements for a token (whale tracking) Use when: You need to detect large token transfers that may signal institutional moves, accumulation, or sell-offs. Not for: you need one address's holdings — wallet_balance; exchange order-book size rather than on

• verified_route_preview

  Buyer-side trust oracle for the x402 marketplace: "I need X, budget $Y — which tool is real?" Vets Coinbase Bazaar (discover → drop stubs/factory clones → rank by real unique-payer usage → budget-gate). This MCP runs the FREE single-query PREVIEW: it returns the vetted pick (name

• route

  Legacy alias of verified_route (kept for back-compat). Find and judge the best paid x402 tool for a need, within a budget. Discovers across Coinbase Bazaar, drops stubs (no schema / factory clones), ranks survivors by real usage (unique payers × 3 + calls + recency bonus), enforc

• estimate_plan

  Price a multi-tool plan BEFORE spending anything. Submits the tool calls an agent intends to make to the gateway's free /v1/plan/estimate and returns per-step cost, total, a fits-budget verdict, and a cheaper alternative per paid step. No payment, no wallet needed. Use when: plan
