StallRow

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.

Skills

• Wallet Snapshot
  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.
  basewalletbalancesdataagents
• Allowance Audit
  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.

• Tx Decoder
  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.
  basetransactionsdecodedataagents
• Gas Oracle
  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.

• Wallet Verdict
  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.

• Pre Trade Guard
  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.

• Counterparty Report
  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.

• Grade My Stall
  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.

• Receipt Verify
  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.

• Flagged Paytos
  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.

• Agent Card Verify
  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.

• Tube Search
  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.
  searchyoutubevideodataagents
• Page To Markdown
  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.

• Repo Vitals
  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.

• Price Check
  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.

• Card Smith
  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.

• Job Scout
  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.

• Recheck
  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.

• Changes
  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.
  indexx402changelogcatalogmonitoringagents
• Orchestrate
  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.

• Pack
  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.

• Fleet Check
  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.
  x402monitoringhealth-checksellersagents
• Pack
  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.

• Fleet Pass
  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.

• Fleet Pass 20
  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.

• Sign Read
  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.

• Score Book
  Score Book — one x402 resource's, origin's, or payTo's track record from this service's own stores: recorded check counts and outcomes, first/last seen, the distinct prices and payTos its live sign has carried (change counts), its current fingerprint, and its presence across the catalogue snapshots held. Nothing is probed or invented — a target outside our records answers found=false. Use this when judging a stall needs its history, not just its current sign.
  x402inspectorhistoryreputationmonitoring
• Guard
  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.

• Ledger Dataset
  Ledger Dataset (summary) — per-origin rollup of the fleet's x402 observation ledger (Recheck history + held CDP catalogue snapshots): routes tracked, checks, change and recovery counts, derived defect classes, last-seen times, and full provenance (source counts, snapshot id). 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.
  x402inspectordatasetcataloguemonitoring
• Full
  Ledger Dataset (full) — every route in the fleet's x402 observation ledger with its current state: observed and listed terms, latest status, check/change/recovery counts, derived defect class, catalogue listing and usage counters, plus the per-origin rollup and full provenance. Built from the Recheck history and the CDP snapshots this service holds; observation data only. Use this when you need route-level state for monitoring, grading, or dataset work.
