_ is it live, free and safe measured by this hub
Is agentpay live?
Yes — it answered the hub's last check (checked 3h ago). It answered 100% of checks over the last 30 days.
Is agentpay free to use?
Partly — some of its tools are open, others need a key or payment.
What tools does agentpay have?
25 tools: session_create, pre_trade_check, sbtc_peg, orderbook_depth, route, estimate_plan, verified_route, verified_route_preview, ….
Is agentpay safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • token_price reads open 19h ago

    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 slippage — orderbook_depth.

  • gas_tracker reads open 21h ago

    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 mainnet gas is reported. Returns: slow_gwei, standard_gwei, fast_gwei, base_fee_gwei, estimated confirmation times Example response: {"slow_gwei":1.5,"standard_gwei":2,"fast_gwei":3,"base_fee_gwei":1.2,"source":"etherscan"} Price: $0.000 USDC per call

  • token_market_data reads open 19h ago

    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 exchanges. Not for: you only need the spot price — token_price is lighter; you need pool depth or slippage — orderbook_depth. Returns: volume_24h_usd, market_cap_usd, price_usd, ath_usd, price_change_24h_pct Example response: {"token_a":"ETH","token_b":"USDC","price_usd":2071.45,"volume_24h_usd":312847293,"volume_change_24h_pct":-8.3,"market_cap_usd":249800000000,"ath_usd":4878.26,"price_change_24h_pct":-3.91,"source":"coingecko"} Price: $0.000 USDC per call

  • funding_rates reads open 21h ago

    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, slippage and security for a trade — pre_trade_check. Returns: funding_rate_pct, annualized_rate_pct, sentiment (bullish/neutral/bearish) per exchange Example response: {"asset":"BTC","rates":[{"exchange":"binance","funding_rate_pct":0.012,"annualized_rate_pct":13.14,"sentiment":"bullish"},{"exchange":"bybit","funding_rate_pct":0.011,"annualized_rate_pct":12.04,"sentiment":"bullish"},{"exchange":"okx","funding_rate_pct":0.009,"annualized_rate_pct":9.85,"sentiment":"neutral"}],"source":"binance/bybit/okx"} Price: $0.000 USDC per call

  • dune_query reads open 9h ago

    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, custom metrics. Not for: you have no Dune query ID — the other tools cover prices, derivatives, TVL and security without one; you need sub-second answers — set fast_only=true or use a cached tool. Returns: rows[], columns[], row_count, generated_at from the Dune Analytics query result Example response: {"query_id":3810512,"row_count":2,"columns":["protocol","revenue_usd"],"rows":[{"protocol":"Uniswap V3","revenue_usd":1243800},{"protocol":"Aave V3","revenue_usd":987200}],"generated_at":"2026-03-22T00:00:00Z","source":"dune"} Price: $0.000 USDC per call

  • web_search reads open 9h ago

    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 anything else on the web. Not for: you already have the URL — url_reader; you want crypto headlines with sentiment — crypto_news. Returns: results[] with url, title, description, content; query; count Example response: {"query":"ETH gas fees today","count":5,"results":[{"url":"https://etherscan.io/gastracker","title":"Ethereum Gas Tracker","description":"Real-time Ethereum gas price tracker","content":"Current gas: 2 Gwei..."}],"source":"jina_search"} Price: $0.000 USDC per call

Use when: You need to know total open interest in perpetual futures and whether it's rising or falling. Combine with funding_rates for a full derivatives picture. Not for: you need the funding cost of holding a position — funding_rates; a single trade verdict — pre_trade_check. Returns: total_oi_usd, oi_change_1h_pct, oi_change_24h_pct, long_short_ratio, per-exchange breakdown Example response: {"asset":"ETH","price_usd":2069.73,"total_oi_usd":8420000000,"oi_change_1h_pct":1.2,"oi_change_24h_pct":12.4,"long_short_ratio":1.08,"long_short_ratios":{"Binance":1.08,"OKX":1.11,"Gate.io":1.02},"long_short_spread":0.09,"exchanges":[{"exchange":"Binance","oi_contracts":4066123.5,"oi_change_1h_pct":1.2,"oi_change_24h_pct":12.4,"long_short_ratio":1.08}],"source":"binance/bybit/okx + gate/bitget (L/S)","primary":"binance"} Price: $0.000 USDC per call

  • token_security reads open 14h ago

    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.

Returns: risk_level, is_honeypot, buy_tax, sell_tax, holder_count, owner_address, is_mintable, can_take_back_ownership Example response: {"contract_address":"0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2","chain":"ethereum","risk_level":"low","is_honeypot":false,"buy_tax":0,"sell_tax":0,"holder_count":842341,"is_mintable":false,"can_take_back_ownership":false,"source":"goplus"} Price: $0.000 USDC per call

  • url_reader reads open 14h ago

Use when: You need a combined macro + crypto market overview in one call: S&P 500, Treasury yield, BTC, ETH, and Ethereum gas.

  • pre_trade_check reads unknown never probed

    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 breakdown. Major ERC-20 addresses (LINK, UNI, ARB, OP, AAVE, PEPE, SHIB) resolve automatically; native assets (BTC, ETH, SOL, ...) report security n/a; an unrecognized token without token_address reads 'unknown' and caps the verdict at caution — an unscreened contract can never read 'ok'. Replaces four API integrations and the judgment layer on top of them. Raw component data embedded so you can apply your own thresholds. Stacks tokens (STX, sBTC, USDCx, stSTX, ZEST, LEO, USDh, aeUSDC, stBTC) add the Bitflow DEX venue: price impact at YOUR size from a live route quote, the pools and bins the swap crosses, and their TVL; STX and sBTC keep their CEX perp legs, DEX-only tokens report funding/OI n/a and contract risk unscreened (no GoPlus coverage on Stacks). Use when: An agent (or human) is about to enter a position and wants one verdict covering liquidity, carry, crowding, and security — instead of four raw feeds plus its own synthesis. Not for: you need a single raw factor — funding_rates, open_interest, orderbook_depth or token_security are free; you are not about to size a position. This call settles $0.01 on-chain. Returns: verdict (ok/caution/avoid), factors{liquidity,carry,crowding,security} each with level + reason, components{orderbook_depth,funding_rates,open_interest}, symbol, side, size_usd Example response: {"symbol":"ETH","side":"long","size_usd":50000,"venue":"cex","verdict":"caution","factors":{"liquidity":{"level":"ok","slippage_pct":0.011,"bucket_usd":50000,"reason":"fills within 0.011% of best ask"},"carry":{"level":"caution","median_funding_pct":0.062,"annualized_pct":67.9,"reason":"longs paying elevated funding"},"crowding":{"level":"ok","long_short_ratio":1.4,"oi_change_24h_pct":3.2,"reason":"positioning unremarkable"},"security":{"level":"n/a","reason":"ETH is a native chain asset — no token contract to screen"}},"not_checked":["security"]} Price: $0.01 USDC per call (x402 over MCP: an unpaid call returns PaymentRequired; pay via _meta x402/payment)

  • sbtc_peg unknown never probed

    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 oldest pending age, pending withdrawals, 24h failures), the last peg events with Bitcoin txids, the signer set and signature threshold, and the rolling withdrawal cap with its current headroom. Read from the sBTC token and registry contracts and the bridge API (Emily); a source that fails degrades to null plus a note. Signer liveness is not public and is reported as null — the pending ages and withdrawal headroom are the proxies. Use when: An agent wants the state of the sBTC peg before moving BTC onto or off Stacks, sizing against the withdrawal cap, or reading Bitcoin-capital flow into Stacks as a signal. Not for: you need the sBTC price or market data — token_price / token_market_data are free; you need a swap quote — pre_trade_check prices Bitflow. This call settles $0.01 on-chain.

Use when: You need to estimate slippage before executing a large trade. Tells you how much a $10k, $50k, or $250k order will move the market.

  • route reads unknown 6h ago

    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), enforces the budget, price- tiebreaks quality-equal candidates. Returns ranked candidates + a recommendation + ready-to-pay details. Advise-only — no payment happens here. Prefer verified_route (same vetting, matches the paid tool + Bazaar listing). Use when: "which x402 tool for X", "find a paid API for X under $Y".

  • verified_route reads unknown 39d ago

    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 genuinely-used survivors by real unique-payer usage, and returns ONE vetted recommendation with a ready-to-pay x402 challenge. The credit-bureau check an agent cannot do itself in one query — pay $0.01 to avoid paying a scam or a dead stub. Use when: An agent is about to pay an unknown x402 tool and wants the real, used, non-sybil one under budget — not just the cheapest. Not for: you already know which AgentPay tool you need — call it directly; you only want a free preview of the marketplace ranking — the MCP's free preview (verified_route_preview on the remote server). This call settles $0.01 on-chain. Returns: recommendation (with ready_to_pay), survivors[] (each with typed evidence[]), catalog{scanned, real_providers, sybil_collapsed, biggest_factory}, vetting summary Example response: {"need":"dex pair liquidity","chain":null,"budget_usd":"1","recommendation":{"name":"Otto AI","url":"https://otto.example/dex","price_usd":"0.001","network":"eip155:8453","pay_to":"0x0e84ddedaae6a7","payers30d":200,"calls30d":3246,"quality":3851,"flags":[],"evidence":[{"type":"delivery","source":"agentpay-prober","metric":"delivery_rate","value":1,"n":12,"observed_at":"2026-09-30T13:05:00Z","ref":"/s/otto-example-dex-1a2b3c"},{"type":"third-party","source":"coinbase-bazaar","metric":"unique_payers_30d","value":200,"observed_at":"2026-10-01T12:00:00Z","ref":null}],"ready_to_pay":{"url":"https://otto.example/dex","network":"eip155:8453","price_usd":"0.001","accepts":{"scheme":"exact","network":"eip155:8453"}}},"survivors":[],"catalog":{"scanned":117,"after_vetting":114,"real_providers":41,"unique_wallets":38,"sybil_collapsed":73,"biggest_factory":{"pay_to":"0x2bb72231eed3","listings":72}},"vetting":"swept 17 queries → 117 listings → collapsed 73 sybil listings → 41 real providers"} Price: $0.01 USDC per call (x402 over MCP: an unpaid call returns PaymentRequired; pay via _meta x402/payment)

  • verified_route_preview reads unknown 14h ago

    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 + usage stats + why) and survivor count to PROVE a real provider exists, but WITHHOLDS the provider URL + ready-to-pay x402 challenge. To get those — plus the full multi-query sweep + usage-based sybil-collapse + trust allowlist — call verified_route ($0.01: an unpaid call returns the x402 PaymentRequired, which a wallet-carrying client pays in-band), or use the agentpay-x402 SDK. This preview never charges. Use when: "which x402 tool for X", "find a real/trustworthy paid API for X", "avoid a scam or dead stub", "vet this provider before I pay".

  • funding_spread unknown never probed

    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 minus min, cheapest and dearest venue, deviation from the median), its percentile against the last 7 days of cross-venue spreads, a plain-English read, and — given notional_usd — a carry estimate (per 8h / day / 30d) net of an assumed taker fee with the breakeven holding time. Venues that fail to answer are named in venues_unavailable; the spread is computed over the ones that did. Use when: An agent wants to know whether funding on one venue is out of line with the others for the same perp — to pick the cheaper venue for a position, or to size a long/short carry across venues. Not for: you only need one venue's current funding — funding_rates is free; you want a trade verdict for one venue — pre_trade_check. This call settles $0.01 on-chain.

_ try it over mcp through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id a352d421a5edc3be.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/a352d421a5edc3be/claim. Over MCP: the claim_endpoint tool.

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
