What each plan includes

The rows are the product as it runs today. "Soon" rows are being built and will be included in the plans marked when they ship; nothing here is a plan-only promise.

The evidence packs, one price each

Each pack is one dated JSON file about one agent or one address, with its definition ids and a written list of what it does not assert. Agents buy them per call over x402; Operator includes every pack for 9 of your agents and Team for 60. If there is nothing to sell (an agent never seen paying, an address none of our tables know) the answer is a 404 before any payment.

• Check before you pay · 5¢ (about one agent, /check/precheck?id=<agent>&payto=0x…)
  The routine check before an agent pays or hires another: its level and last observed payment, open incidents, its latest statement (how old, chain intact, flags) and, with payto=<address>, what that address is: label and basis, contract or plain key, how many registered agents paid it, whether this agent paid it before, and whether our poisoning watch saw it planted as a look-alike. Facts only, never a verdict.
  Use as the routine check that costs cents: before trusting, paying or starting work with an agent, and before sending money to the address it gives you.
• State of Agent Money, the depth file · 30¢ (one closed period, /check/edition?period=2026-09, or latest)
  Buy the September 2026 file on the Desk (sign in with a wallet first). The working papers behind the statement: everything behind one final edition: every agent with a counted payment in the period (payments, USD, what left its control, counterparties, top payee), every payee with its label, the edition's figures with definition ids and daily series, and the period's full book. The edition page and its figures stay free; this is the depth.
• What is this address · 3¢ (about one address, /check/venue?address=0x…)
  One address on Base: its label with category, basis and evidence link, contract or plain key (and any EIP-7702 delegation), registered agents that paid it in 30 days and all time with counted USD, whether it is an agent's bound wallet, an x402 seller or a planted poisoning look-alike, and its USDC, USDT and EURC flow over the last 48 hours, read live.
  Use before sending money to an address you were given: what it is, who else pays it and how much moves through it now.
• Which apps move its money · 1¢ (about one agent, /check/builders?id=<agent>)
  The ERC-8021 Builder Codes on this agent's counted payments: payments, USD and share per code, the top payee per code, and how much of its counted spending has been read so far.
  Use to see which apps or wallets build this agent's transactions, for example to confirm it pays through the integration it says it uses.
• Liveness card · 1¢ (about one agent, /check/liveness?id=<agent>)
  L0–L9 rank with the evidence behind it: bindings, first and last observed payment, float, delegation. No raw keys. Packages what the free agent record shows into one dated, citable file with its receipt.
  Use before trusting, paying or funding an agent: it tells you whether this registration has ever been seen moving money, and from which wallet.
• Incident pack · 1¢ (about one agent, /check/incidents?id=<agent>)
  Every detection logged on this id, newest first, with the kind explained. The same detections the free record lists, as one dated, citable file with its receipt.
  Use for due diligence on one agent: every anomaly our detectors logged on it, with severity and whether it is live.
• Statement history · 1¢ (about one agent, /check/statement?id=<agent>)
  The agent's last 24 three-hour statements (outflow split into spend and routing hops, what left its control, income, open flags), each with its keccak-256 hash, the prevHash link that chains them, and a Merkle proof against the signed root of its window.
  Use before paying an agent: confirm its statement chain is current and unbroken and verify any statement against the published, signed root.
• Peer slice · 1¢ (about one agent, /check/peer?id=<agent>)
  Up to 10 ranked agents that pay the same top counterparty as this one.
  Use to find comparable agents, or the other customers of the same service, for benchmarking or outreach.
• Drain shape · 2¢ (about one agent, /check/drain?id=<agent>)
  The public 5× / $250 / never-paid rule applied to this wallet's payments, and whether it tripped. The rule and the payments are public; this is the dated, citable answer with its receipt.
  Use when a wallet you operate or insure may have been drained: a dated yes/no on the drain rule with the transaction that tripped it.
• Did its wallet empty out · 3¢ (about one agent, /check/exit?id=<agent>)
  Every window in which a new payee took most of this agent's outflow within 72 hours, at the drain thresholds: the payee, its label, contract or plain key, how many registered agents pay it, whether the agent paid anyone else in the 30 days after and since, and its status under drain.abandoned.v1 (candidate, pending, resumed or service). For up to three windows, the second hop read live: where the payee sent the money next, how soon, and what that address is. Candidates, never verdicts.
  Use when an agent you run, insure or depend on went quiet: whether its money left through one fresh address, and where it went next.
• Who paid this address · 2¢ (about one address, /check/counterparty?address=0x…)
  The registered agents that paid this address in counted payments (after they were registered, never a routing hop): first and last seen, payments, counted USD, distinct payers and distinct L7+ payers, the top payer's share, and the 100 largest payers by counted USD with level, binding method and confidence, and their latest transaction hashes (payers_total gives the full count).
  Use before selling to, buying from or partnering with a service: see which ranked agents actually pay it, and how concentrated that is. An address that only received routing hops has no pack.
• Where I pay · 5¢ (about one agent, /check/paygraph?id=<agent>)
  Counterparties, 30-day USD, rail split, idle flag, top-counterparty share. Computed from the free agent record, delivered as one dated, citable file with its receipt.
  Use to see who an agent actually pays and how concentrated that is, for example before accepting it as a customer or a counterparty.
• Where did the money go · 5¢ (about one agent, /check/trace?id=<agent>)
  This agent's exits (its dominant-share windows, else its largest payments of the last 90 days that left its control to an address that is not a service), each followed live up to three hops: where each address sent the money next, keeping the destinations that carry most of the value; on every hop its label, contract or key, whether an issuer froze it, whether it received DAI or WETH within a day (a swap out of a freezable token), whether the same key is active on Tron, and whether the agent probed the first hop with a tiny payment before the large one. Stops at a contract, a labelled service or a key busy enough to be one. Facts and candidates, never a verdict.
  Use when an agent you run, insure or depend on lost its money: where it went, how far it can still be followed, and whether any address on the way is frozen or active on Tron.
• Operator pack · 10¢ (about one agent, /check/bundle?id=<agent>)
  liveness + paygraph + drain + incidents in one pack.
  Use when you need the whole picture of one agent in one call: rank evidence, payment graph, drain rule and incidents together.
• Revaluation · 25¢ (about one agent, /check/reval?id=<agent>)
  Re-probe this registration now from our sandbox (tokenURI, registration file, declared endpoints) and compare with the last stored probe. One per registration per hour.
  Use when a stored probe is too old for your decision and you need the endpoint checked right now.

How paying works

1. Connect and sign in. Any wallet that can sign a message: MetaMask, Coinbase Wallet, Rabby, Trust, Phantom, or a Base Account with a passkey. No password, no key, no gas.
2. Pick a plan and a length. 30 days, 90 days or a year. The server quotes the exact USDC amount and the receiving address.
3. Approve once in your wallet. You sign an authorisation for exactly that amount (EIP-3009). Coinbase's facilitator settles it on Base and pays the network fee. Your plan starts at once and the transaction is your receipt.
4. It ends when the period ends. Nothing can pull more money from your wallet. Buy again when you want more time; buying a different plan mid-period switches at once and adds the days.

Where the money goes

Straight to one published receiving address on Base, the same one the checks' manifest at /.well-known/x402 names. We never hold your funds or keys. Refund of the unused days within 14 days of paying, for any reason, in USDC to the paying address; the Terms, section 6A have the details.

For agents and for data teams

An autonomous agent does not sign up: it reads any ranked agent's record free at /api/agent?id=, and buys a dated evidence pack per call over x402 when it needs one it can cite. Prices are stated in the 402 response before anything is charged, and a registration we have never seen paying anyone is refused before payment.
