Registry code: efb8c5ec74f8e0ac

api record

A row of small x402 stalls in one service: Base chain reads (wallet snapshot, allowance audit, transaction decoder, gas oracle), a wallet trust verdict, fetch tools (YouTube search, page-to-Markdown, GitHub repo vitals), seller tools (Bazaar price-check, agent-card smith), a digest of open agent jobs, and scheduled change detection for x402 resources and web pages, with prepaid check packs. Use this when an agent needs one cheap, honest fact mid-task and cannot run the source itself.

Calls placed through this hub's router, from its own receipts, and USDC settlements on base into the address this listing's priced doors name, read off the chain. Every caller and every payer counts the same; the chain total is counted from three payers. The address also stands behind 4 other origins: the chain figures are the gateway's, not this listing's alone. How it is counted.

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.

  • v1-tube-search unknown never probed

    YouTube search results as clean JSON: title, video id, URL, channel, duration, and views for each result, scraped from the public results page with no API key. Use this when an agent needs to find a video mid-task and cannot drive a browser or hold a Google API key.

  • v1-fleet-check unknown never probed

    Fleet Check — one health sweep of your whole x402 fleet: name resource URLs and/or origins (expanded from their own /.well-known/x402) and get a per-route table — alive, status, whether the 402 challenge decodes, each accept's network/asset/payTo/amount, an OK / DEGRADED / DOWN verdict naming the defect, and a grade per origin. Probes are unpaid only — this route never pays any route it checks. Use this when you run more than one x402 stall and want one honest answer about all of them.

  • v1-wallet-snapshot unknown never probed

    Snapshot one Base wallet in a single call: ETH balance, top token holdings, first and last activity, and outgoing transaction count. Use this when an agent needs a wallet's shape before deciding to pay, trust, or transact with it. Explorer fields that cannot be supplied come back marked unknown, never invented.

    basewalletbalancesdataagentsonchain-dataaddress-lookup

  • v1-allowance-audit unknown never probed

    Audit one Base wallet's ERC-20 approvals against a curated list of major spenders (Permit2, Uniswap, Aerodrome, aggregators): active approvals are listed and unlimited ones flagged high risk. Use this when an agent or its owner wants to know what a wallet has already authorized before it holds or moves funds. When the explorer cannot supply the held-token list, the token-dependent fields come back marked unknown rather than the call failing.

    basesecurityapprovalsallowanceagentserc20-approvalsspender-riskpreflight

  • v1-tx-decoder unknown never probed

    Decode one Base transaction into plain English: sender, receiver, ETH value, status, the known method behind the selector, every ERC-20 transfer it made, and a one-sentence summary. Use this when an agent needs to explain or verify what a transaction actually did before acting on it.

    basetransactionsdecodedataagentstx-decodetransaction-lookuponchain-data

  • v1-gas-oracle unknown never probed

    Current Base gas in one call: the live gas price, the current base fee, the base-fee range across the last 20 blocks, whether fees are rising, falling, or flat, and a cheap-window hint drawn from that data. Use this when an agent wants to time a transaction instead of paying whatever the moment charges.

    basegasfeesdataagentsgas-pricebase-feesfee-estimate

  • v1-wallet-verdict unknown never probed

    A trust verdict for one Base wallet: OFAC SDN exact-match against a dated snapshot, wallet age, activity level, and an address-poisoning scan of its recent token transfers, combined into SAFE, CAUTION, or AVOID with a 0-100 score and itemized reasons. Use this when an agent must decide whether a wallet is safe to pay or take instructions from.

    basesecuritysanctionsverdictagentswallet-risktrust-verdict

  • v1-pre-trade-guard unknown never probed

    Pre-Trade Guard — before you pay an x402 listing, screen the payTo you are about to pay: its Verdict Index catalog history (first seen, payTo rotations, listings added or removed across the snapshots held), an OFAC SDN exact-match check, and the wallet's Base age and activity, combined into PROCEED, CAUTION, or ABORT with itemized reasons. Use this when an agent is about to pay a payTo it has never paid before.

    x402securitysanctionsverdictpaymentsagentspre-trade-guardpaytopreflightcounterparty

  • v1-counterparty-report unknown never probed

    Counterparty Report — one bundled report on one seller: the payTo's wallet snapshot, an OFAC SDN exact-match screen, and its Verdict Index listing history, plus a Token Verdict when you name a token, a LockSmith audit when you name a service URL, and a ListSmith grade when you name a listing URL. Legs that are not requested or cannot run are marked, never padded. Use this when an agent is about to rely on a seller it has never dealt with.

  • v1-grade-my-stall unknown never probed

    Grade My Stall — a seller-side report card for one x402 resource: a live unpaid probe (does it answer 402 with a parseable challenge?), the description measured against the 500-character limit, CDP listing presence in the newest catalog snapshot, Settled's record, the origin's x402scan ownership declaration, and payTo consistency across sources. Checks that cannot be performed report unverified, never a guess. Use this when you run a stall and want to know how buyers' tools see it.

    x402sellerslistingsverificationlisting-gradepreflightdiscoveryendpoint-verification

  • v1-receipt-verify unknown never probed

    Receipt Verifier — a Base transaction hash in, a normalized verified receipt out: payer, payTo and amount from the USDC Transfer log, asset and network, settled status and confirmations. When the payTo is this fleet's own and the amount matches a priced route, routes at that price are listed as candidates — an amount alone never proves which route was called. Unknown transactions error honestly, unsettled. Use this when someone claims they paid and you want the chain's version. Base only.

    x402paymentsverificationreceiptssettlement-prooftx-verificationdelivery-verified

  • v1-flagged-paytos unknown never probed

    Bad-payTo Registry Feed — the currently flagged payTos, each with its evidence: every address in the bundled OFAC SDN snapshot, payTos the newest catalog snapshot pair shows rotated away from live listings, and payTos of listings that vanished between snapshots. Built from the same two sources the Pre-Trade Guard screens against. No entry without evidence; entry and evidence caps are stated, never silent. Use this when a router or guard wants the fleet's current avoid-list in one cheap call.

    x402securitysanctionsregistryagentspaytoblocklistrisk-feed

  • v1-agent-card-verify unknown never probed

    Agent-Card Verifier — an ERC-8004 agent id (resolved on Base via the registry) or an agent.json URL in; the card is fetched and checked against live reality: declared endpoints probed unpaid (402 is correct for a paid service), challenge payTos compared with the card's declared wallets, declared prices with live challenge amounts. Undeclared fields report not_checked, never a guess; an unreachable card errors honestly, unsettled. Use this when an agent's card claims more than its endpoints do.

  • v1-page-to-markdown unknown never probed

    Fetch one web page and return its main content as clean Markdown with title and word count, extracted server-side. Private and loopback targets are refused. Use this when an agent needs to read a page inside a workflow without a browser and without wading through navigation and boilerplate.

    fetchmarkdownwebreadingagentsweb-fetchcontent-extraction

  • v1-repo-vitals unknown never probed

    Vital signs for one GitHub repository in a single call: stars, forks, open issues, license, last push, archived flag, and a 0-100 health score with a verdict line. Use this when an agent is choosing a dependency, a repo to contribute to, or a project to trust, and needs the quick read before the deep one.

    githubreposdataagentsgithub-reporepository-health

  • v1-price-check unknown never probed

    Pricing comps for an x402 listing, read live from the CDP Bazaar public catalog: how many resources match your keywords, their price distribution, the closest comparables, and a recommended listing price with its rationale. Use this when you operate an x402 route and are setting or changing its price.

  • v1-card-smith unknown never probed

    Generate or grade an agent card (the /.well-known/agent-card.json an agent publishes for A2A and AgentWorld-style registries). Generate builds a structurally valid card from your fields; grade scores a supplied card and itemizes its defects. Use this when you are registering an agent and want the card right the first time.

  • v1-job-scout unknown never probed

    A digest of currently open agent jobs from the marketplaces we sweep daily, filtered by the capabilities you name and sorted by budget: platform, budget, capability tags, deadline, and source snapshot time on every row, with a stale flag when the snapshot ages past 24 hours. Use this when your agent is looking for paid work.

    jobsbountiesagentsworkdigestagent-jobsbounty-board

  • v1-recheck unknown never probed

    Probe one x402 resource or page WITHOUT paying it: BASELINE / UNCHANGED / CHANGED with a diff (price, asset, payTo, schema, body) vs the last check. Use this when a scheduled agent must know what changed first. Watch and pack state persist across redeploys on the service volume. Checking the same endpoint on a schedule? Buy the pack instead — POST /v1/recheck/pack is $1 for 250 checks (90 days) and this route spends pack credits when you send pack_id, so a loop makes one payment, not hundreds.

    monitoringx402change-detectiondiffagentsdriftuptimeendpoint-verificationpayto

  • v1-index-changes unknown never probed

    Verdict Index — the CDP Bazaar catalog changelog: the diff between our two newest full-catalog snapshots (price, asset, network, payTo, description, service name), with added and removed resources counted. Snapshots refresh about every 6 hours; until two exist this returns 502 and charges nothing. Filter by resource, payTo, service name, or network — every chain covered, Solana included; the summary breaks counts down by network. Use this when a router needs what changed since its last sync.

    indexx402changelogcatalogmonitoringagentsdriftcatalogue-diffcatalogue

  • v1-orchestrate unknown never probed

    One combined fleet report for $0.75: Token Verdict's verdict on a token, RouteVerdict's delivery check and LockSmith's security audit summary on a service URL, and ListSmith's grade on a listing URL — four fleet services in one call. A failed leg is marked in the report, not hidden; only a total failure returns 502 and charges nothing. Use this when an agent is about to trust a token and a stall in the same workflow and wants one receipt instead of four payments.

    bundlex402verdictauditagentsfleetfleet-auditpreflightbundle-report

  • v1-recheck-pack unknown never probed

    Recheck watch pack — the default for monitoring loops: one $1.00 payment buys 250 change-checks for ONE endpoint ($0.004 per check instead of $0.005), good for 90 days. Returns an unguessable pack id — spend credits via POST /v1/recheck (body pack_id or X-Recheck-Pack header); read the balance free at POST /v1/recheck/pack-balance, and an exhausted pack returns 402 rather than charging per call. Use this when anything checks the same endpoint more than ~3 times a week.

    monitoringx402change-detectionprepaidagentsdriftuptime

  • v1-fleet-check-pack unknown never probed

    Fleet Check pack — the standing form of Fleet Check: one $5.00 payment buys 100 sweep credits for ONE fixed fleet definition (resources and/or origins), good for 90 days. Sweeps run on your interval or on demand via POST /v1/fleet-check/run — one credit per sweep, never per route — diff against the last sweep, and POST failures and recoveries to your webhook (heartbeats optional); the latest table is free at POST /v1/fleet-check/status. Use this when your stalls should be watched continuously.

    x402monitoringprepaidhealth-checkagentsfleet-healthuptimeendpoint-verificationdrift

  • v1-fleet-pass unknown never probed

    Fleet Pass — one prepaid balance for the whole fleet: one $5.00 payment buys a $5.00 balance that spends on any paid route across Token Verdict, RouteVerdict, ListSmith, StallRow and LockSmith, each call debited at that route's listed price (90 days). Send the pass id as the X-Fleet-Pass header; read the balance free at POST /v1/fleet-pass/balance. Use this when a loop calls more than one fleet service and wants one budget, not a payment per call.

    prepaidx402budgetagentsfleetprepaid-balancefleet-pass

  • v1-fleet-pass-20 unknown never probed

    Fleet Pass v2 — the $20 working pass for agent frameworks: one $20.00 payment buys a $20.00 prepaid balance that spends on any paid route across Token Verdict, RouteVerdict, ListSmith, StallRow and LockSmith, each call debited at that route's listed price — no holder discounts (90 days). Send the pass id as the X-Fleet-Pass header; read the balance free at POST /v1/fleet-pass/balance. Use this when a framework loop calls the fleet often enough that a $5 pass would run dry mid-run.

    prepaidx402budgetagentsfleetframeworksprepaid-balancefleet-pass

  • v1-sign-read unknown never probed

    Sign Reader — read one x402 endpoint's 402 challenge: both wire formats (v2 PAYMENT-REQUIRED header, v1 JSON body) parsed and normalized (network, asset, amount atomic and exact decimal, payTo, scheme), malformed fields named, declared-vs-live mismatches (method included) when you pass your catalogue entry, and a compatibility verdict for the official Python and TypeScript x402 SDKs. Probe is unpaid. Use this when a checker's parser keeps choking on sellers' signs.

    x402inspectorchallengesdkverificationdiscoverymanifestpreflightchallenge-parse

  • v1-score-book unknown never probed

    Score Book — an x402 target's track record from our records: check history, prices/payTos carried, catalogue presence, and — for url/origin — patrol facts from the patrol snapshot (open defects by class, first/last seen; recoveries with receipt ids; snapshot provenance). Patrol is periodic — facts are as of the snapshot, never live; it holds no payTo data, so payTo patrol sections are empty. Unknown: found=false. Use this when judging a stall needs its history, not just its current sign.

    x402inspectorhistoryreputationmonitoringtrack-recorddriftcatalogue-presence

  • v1-guard unknown never probed

    Guard — one pay / caution / avoid verdict for one x402 endpoint, composed from the row's inspector tools: the live 402 sign read and SDK-checked, the payTo screened against the bad-payTo registry (OFAC plus rotation/vanishing flags, evidence attached), and the resource's recorded history — unknown history caps the verdict at CAUTION. Every verdict carries its reasons; the one probe inside is unpaid. Use this when your agent is about to pay an endpoint it does not know.

    x402inspectortrustpre-paysecuritypre-trade-guardpaytopreflighttrust-verdict

  • v1-physical unknown never probed

    Inspector Physical — the full pre-pay workup for one x402 resource in ONE $0.05 call (the singles sum to $0.075): Sign Reader's challenge report, Score Book's track record, Guard's PROCEED/CAUTION/ABORT verdict as the headline, and a Recheck that probes and records the target (BASELINE/UNCHANGED/CHANGED, in the public feed). No RouteVerdict leg. Bad targets are delivered reports; only SSRF refusals are 422. Use this when your agent wants one endpoint's complete picture before paying it.

  • v1-payto-pin-verify unknown never probed

    PayTo Pin Verify — check one pinned x402 route against its first-seen payTo set: a fresh unpaid probe compares the live payTo set with the pin's hash-committed baseline, answering MATCH, MOVED with before/after sets, or ROUTE_GONE as a delivered report. A swap fires one signed PAYTO_MOVED webhook per distinct new set. Pins are created free at POST /v1/payto-pin. Use this when a payTo swap must be caught before you pay the route again.

    x402inspectorpaytomonitoringverificationdriftpin-verify

  • v1-toolkit-pack unknown never probed

    Toolkit Pack — the prepaid form of the inspector toolkit: one $1.00 payment buys 125 checks spendable on Sign Reader, Score Book, or Guard in any mix ($0.008/check instead of the $0.01 singles), good for 90 days. Spend credits via POST /v1/sign-read, /v1/score-book, or /v1/guard (body pack_id or X-Toolkit-Pack header); read the balance free at POST /v1/toolkit/pack-balance. An exhausted pack returns 402 rather than charging per call. Use this when your agent runs the toolkit regularly.

  • v1-ledger-dataset unknown never probed

    Ledger Dataset (summary) — per-origin rollup of the fleet's x402 observation ledger (Recheck history + held CDP snapshots + the committed patrol snapshot): routes, checks, change/recovery counts, patrol open defects and recoveries by class, last-seen times, provenance. Observation data only — no operator contacts. Use this when you want the town-wide state of the x402 catalogue before buying the full per-route pull.

    x402inspectordatasetcataloguemonitoringobservation-ledger

  • v1-ledger-dataset-full unknown never probed

    Ledger Dataset (full) — every route in the fleet's x402 observation ledger: observed/listed terms, latest status, check/change/recovery counts, derived defect class, catalogue listing + usage counters, and its patrol block (open defect by class, first/last seen; or recovery + receipt id), plus the per-origin rollup and provenance. Sources: Recheck history, held CDP + patrol snapshots; observation data only. Use this when you need route-level state for monitoring, grading, or dataset work.

_ try it 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 agent card — 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 efb8c5ec74f8e0ac.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/efb8c5ec74f8e0ac/claim. Over MCP: the claim_endpoint tool.
