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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

Change detection for anything with a URL, built for monitoring loops: probe one x402 resource or web page WITHOUT paying it and answer BASELINE, UNCHANGED, or CHANGED with a field-by-field diff (price, asset, payTo, schema, page body) against the last check for that watch. Use this when an agent runs on a schedule and needs to know what changed before spending money or attention. Watch state is pe

Recheck watch pack: one $1.00 payment buys 250 change-checks for ONE endpoint ($0.004 per check instead of $0.005), good for 90 days. Pack credits persist across redeploys on the service volume. Returns an unguessable pack id — spend credits via POST /v1/recheck (body pack_id or X-Recheck-Pack header), and read the balance free at POST /v1/recheck/pack-balance. Use this when a monitoring loop chec

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. Us

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 summa

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 i

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

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, u

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

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

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, n

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 neve

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 f

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

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

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 retur

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 unpai

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. Unkno

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 unpa

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 refusal
