api record

x402 Bazaar — check, then act, for agents on Base and NEAR. Before buying a token: pre_trade_gate (Base) or near_pre_trade_gate (NEAR) → GO/HOLD/STOP. Then swap: base_swap (best DEX price on Base, returns a ready-to-sign transaction) or near_swap (any chain via NEAR Intents, returns a deposit address); funds never pass through this server. Plus wallet/account intelligence, B20 token controls, lending health, web and AI reads. Paid per call over x402. Configure an x-credit-token header (buy once via buy-credits, no wallet) for unlimited calls; otherwise 1 free call/day per tool. No USDC on…

whale_flow 0.04 USDC paid never probed
Is size moving to the exits right now? — Flow, not snapshot: the largest transfers of a Base token in the last 24h, classified by whether whales are sending INTO DEX pools (sell pressure) or pulling OUT (accumulation) — a net sell-pressure read that decays in hours. Complements holder-forensics ('who could dump') with 'is anyone dumping now'. CDP-indexed events. Required input: address. Priced $0.04 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls (no free tier on this tool). No API key required.

base_withdrawal 0.04 USDC paid never probed
When can a Base→L1 withdrawal be finalized? — Beryl (2026-06-25) cut the single-proof withdrawal window from 7 days to 5, with a dual-proof fast path at ~1 day. Given a Base withdrawal-initiation tx, this decodes the L2ToL1MessagePasser event (the withdrawalHash, target & value needed to prove/finalize on L1) and estimates the finalization windows under the post-Beryl rules. For agents managing cross-chain liquidity. Required input: tx. Priced $0.04 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls (no free tier on this tool).

lp_lock 0.02 USDC paid never probed
Is liquidity locked, how much, until when? — Surfaces the LP holders, how much of the LP supply is locked or burned vs pullable, the lockers, and unlock dates. Unlocked liquidity is the clearest rug setup — this shows the detail a one-line 'LP locked: yes/no' hides. Required input: address.

Who created this token — and can you trust them? — Profiles the token's creator wallet: how much history it has, how much of the supply the creator still holds, and whether ownership is renounced — rolled into a 0-100 reputation score with signals. A fresh wallet holding 20% of supply with no renounce is the classic rug setup; this is the forensics layer other checks skip. Required input: address.

I'm about to pay 0x… $X — go? (amount-aware recipient screen) — A pre-payment gate for an agent about to send USDC. Screens the recipient (OFAC sanctions, Coinbase/Basename identity, wallet vs contract, fresh-address age) and escalates a fresh or anonymous recipient to STOP once the amount is material — a few cents to a new address is sampling, real size to one is the drain to avoid. Pass usd= for amount-aware guidance. One verdict (GO/REVIEW/STOP). Identity is not intent; not financial advice. Required input: to.

token_unlock 0.02 USDC paid never probed
When does locked LP unlock — is a cliff coming? — Turns raw LP-lock data into a forward calendar: each unlock with its date, the % of LP it frees, the locker (UNCX / Team Finance labelled), and days away — flagging imminent unlocks (<30 days). An LP unlock is a scheduled price event: the moment a rug becomes possible. For agents managing open positions. Required input: address.

rug_monitor 0.1 USDC paid never probed
Get alerted the moment liquidity is pulled — Pay once to watch a Base token's liquidity. We snapshot a baseline and, every 10 minutes, POST your webhook if liquidity collapses (a liquidity pull — the actual moment of a rug). Not price moving — the pool being drained out from under you. Deliveries are HMAC-signed (secret returned once at registration) and retried up to 3 times. Expires after 30 days. Required input: token.

trending_tokens 0.01 USDC paid never probed
What is trending on Base DEXes right now — Use when an agent hunts what is moving on Base. Up to 15 trending Base pools ranked by live DEX activity (GeckoTerminal): token address, pool, DEX, price, 24h change, volume, liquidity and trade count. Paid DexScreener promotions are listed separately, never mixed in. Trending is not safety: vet with token-risk before buying.

sanctions 0.02 USDC paid never probed
Is this address OFAC-sanctioned? — Use before an agent pays, receives from or onboards a wallet: an OFAC sanctions / AML screen of the address against the US Treasury SDN list of sanctioned digital-currency addresses. Direct-address match with a GO/STOP receipt, for compliance agents and payment bots that must screen counterparties before transacting. For many addresses at once use sanctions-batch; for a person or company name use sanctions-name. No API key. Required input: address.

WHO can mint, seize, freeze or pause this B20? — b20-safety tells you WHICH powers a B20 has; this tells you WHO holds them. Reads the token's role-based access control (mint / burn / seize-via-burnBlocked / pause / admin) from onchain role events and reports the exact controllers, how centralized they are, and whether admin has been renounced.

Every silent balance rescaling this token ever did — An Asset B20's multiplier rescales EVERY holder's balance in one call — no transfer, no per-account event, nothing in your tx history. b20-rebase shows today's value; this replays the full MultiplierUpdated history and flags DOWNWARD moves that silently cut every holder.

Mint headroom & dilution history of a B20 — The dilution half of B20 rug risk (b20-safety covers seizure). Reads supply cap vs minted supply (how much can still be minted) plus the on-chain SupplyCapUpdated history — an issuer that RAISED the cap diluted, or set up to dilute, holders. Uncapped mint is flagged as the worst case. Pair with b20-control to see who holds the mint role. Required input: address.

stock_position 0.04 USDC paid never probed
How many shares does this wallet actually control? — B20 Asset tokens do NOT apply multiplier() to balanceOf() — measured on chain: a multiplier moved 1.0→2.0 while holder balances read identically. Coinbase settles splits and dividend adjustments on its 13 tokenized equities through that multiplier, so reading balanceOf as a share count is wrong by exactly that factor the day one fires. Returns both numbers per holding: what an unadjusted integrator shows, and what is owed. Wallet balances only; LP/lending is declared excluded, never zeroed. Required input: wallet.

Returns a single GO / HOLD / STOP with every signal that produced it. Built for the moment an agent has to trust an invoice, a new vendor or a payment-detail change — the classic fraud pattern is a real-looking name on a domain registered weeks ago.

Add list=true to pull EVERY repeated record on the page (listings, table rows, search results) as an array — that mode costs $0.06, since it needs a much larger output budget.

Breadth with no depth in a short burst is the crawler/sampler pattern; a repeat or sustained payer is the opposite. Sees only Base USDC; absence reads as 'thin', never bad. Not financial advice. Required input: wallet. Priced $0.03 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No API key required.

fear_greed 0.002 USDC auth-required never probed
The market-mood gauge every trading agent checks (0–100) — The crypto Fear & Greed Index (alternative.me): 0 = extreme fear, 100 = extreme greed, from volatility, momentum, volume, social and dominance — plus the day-over-day change and recent history. The one-number market-mood read an agent uses to size risk. Pass days= for history (up to 30). A sentiment gauge, not a signal. Not financial advice. Priced $0.002 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No API key required.

Always-returns health check — the cheapest end-to-end x402 test — The cheapest possible end-to-end x402 purchase: always returns 200 with a timestamp (and echoes an optional message). Use it to verify your x402 client, the payment path and our settlement in one sub-cent call before wiring up a real endpoint — the pattern crawlers and monitors hit most across the network. Priced $0.002 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No API key required.

corporate_actions 0.03 USDC auth-required never probed
Announced dividends and splits on Base's tokenized stocks, before they land — Dividends and splits on a tokenized stock settle by moving its multiplier; balanceOf never changes, so a naive reader is silently wrong. Coinbase announces each one on chain days ahead. This lists every announced action across all tokenized stocks Coinbase lists, plus any ERC-8056 schedule, and with wallet= which touch that wallet's holdings. Lenders pause a stock's reserve while one is applied. Not financial advice.

_ 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.

Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
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.
Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id fb374acf192349c7.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/fb374acf192349c7/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/fb374acf192349c7/badge.svg)](https://brick.blue/agent/fb374acf192349c7?ref=badge)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we knowoff the mcp door

card completeness

100%

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.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
