Call this FIRST whenever you hold something other than a wallet address. Give it a transaction hash, an http(s) URL, a hostname or an ERC-8004 registration number and it says which party that is, with the evidence for the link, so the other tools here can then be called with the address. It never picks between candidates: where a hostname or id matches several parties, `address` comes back null an

Call this before connecting to a service. Give it the http(s) URL of an MCP or A2A endpoint and it says who declares it, whether our daily probe reached it, what it answered with, and how many of the last readings answered. It keeps three things apart and never merges them: what an identity DECLARES the endpoint offers, what a probe OBSERVED, and the readings behind that. Read `drift` where presen

Call this immediately before sending a payment, every time — not once per counterparty. It weighs THIS payment (the amount, the chain, the endpoint) against what the address has actually done: the price the seller themselves published for that endpoint, the address that endpoint names as its payee, the largest payment this address has ever received, and whether it has ever been paid on the chain y

SEND `exitAmountUsd` WITH THE POSITION YOU ARE WEIGHING and this answers whether that size has ever cleared here: the schema has carried it since 2026-10-08, and an auditor still had to find it by guessing because this sentence did not say so. Without it the answer still describes the capacity; with it, `exitCapacity` says `covered-now`, `above-declared` or `unknown` for your amount, and whether a

SIX RISKS, NOT ONE WORD, across every vault we score. A risk band is a weighted whole and a reader takes it as a summary of everything, which it is not: ours weighs drawdown, crowding, exit, concentration and consistency, and it contains NO reading of who may move the money. Two vaults read `low` while a multisig needing a single signature controlled them. So this groups what is already measured i

BEFORE YOU TRUST ANY COVERAGE FIGURE FROM US, ask this. It says how much of the market each vault reading actually covers, counted TWO WAYS: by number of open vaults and by the capital in them. They differ by a lot, and the difference is the finding — more than half our vault COUNT is one venue’s small automated vaults, so a count-weighted coverage figure is mostly a statement about that venue and

Everything we hold about one subject, as edges, each carrying where it came from. Use it when you need to explain a decision rather than just make one, or to see what is MISSING before you act. Every edge has `source`, `observedAt` (when the world was in that state), `asOf` (when we read it — a fresh read of a stale fact is not a fresh fact), a `confidence` that names what it is confident IN, its

Call this when you are about to DO something and need one answer you can act on: pay an address, connect to an MCP server, call a tool, or put capital into a vault. The answer depends on the AMOUNT, the ACTION, the POLICY you name and how much we actually read — so the same address can be `allow` for $5 and `abstain` for $5,000. Four decisions. `allow` means nothing we could check objects, up to `

WALK THE WHOLE PURCHASE OF AN x402 ENDPOINT WITHOUT PAYING, in the order a buyer actually asks the questions, stopping at the first one that objects. Every other tool here answers ONE question about one subject; the losses live between them. Five steps: is the endpoint there, what does it charge RIGHT NOW, does the seller’s own catalogue entry agree with what it just said, does the record say anyt

WHICH ENDPOINTS CONTRADICT THEIR OWN LISTING: they ask to be paid at an address the catalogue entry they published does not name. This is the one reading here that cannot be reproduced from anywhere else — an uptime checker sees a live endpoint and a catalogue reader sees a published payee, and only holding BOTH shows the contradiction. A disagreement is between two statements by the SAME party, s

WHICH ENDPOINTS A PAYEE SELLS, or which ones match some text. The sharpest check a payment can get is the endpoint being bought, and until this a caller had to know its URL by heart. Nearly every catalogued resource names a payee, and the catalogue holds tens of thousands of them. Every field is the SELLER’s own catalogue entry and never our reading of it, and a listing is not evidence that the en

The policies evaluate_action can be run under, in full: every rule, its id and the sentence it checks. Published deliberately, including to the agents being evaluated — a rule nobody can read is a rule nobody can correct. Free.

Before paying or hiring an agent: what the chain records about that address. Independent payers (counterparties that paid it and were never paid back), the ones it does pay back, how concentrated its custom is, WHETHER THOSE INDEPENDENT PAYERS ARE INDEPENDENT OF EACH OTHER under `independence`, WHAT IT ITSELF RESTS ON under `restsOn` (how many parties it pays and how much of its spending goes to t

Before putting capital into a vault: what the record shows about it. The headline is what a holder ACTUALLY EARNED set against the advertised rate, with the risk band, the components that apply, who runs it, and `keys`: who can move the money. Read `keys.actsAlone` before any return figure, because a strategy can be excellent and one private key away from being emptied; across what we read, a sing

Find a vault by what it has DONE rather than what it is called. Free. The filter worth knowing is `earned`: `short` returns the vaults where a holder earned LESS than the venue advertises — how many there are is in the answer, never here — and `beating` the ones where they earned more. It matches only vaults whose realised return is COMPARABLE with an advertised one, which is a SMALL part of the o

The question that follows vault_check: who runs the money, and how much of it is their own. Free. Read `ownShare` with its limits, which travel inside it: the leader’s holding is readable on Hyperliquid and Drift ONLY, so elsewhere it is ABSENT and not zero, the median describes the strategies we can read rather than the manager, and a large own-share is evidence of alignment and never proof, beca

The vaults we read, so a caller holding a name rather than a slug can find the one it means. Free. Absence from this list means we do not read that vault, never that it does not exist.

Find agents to hire by what the chain records rather than what they claim: filter every address ever paid on x402, Virtuals ACP, the Olas mech marketplace or Masumi by independent payers, dealings, ACP completion, whether its declared service answers, whether it pays its own payers back, how spread its own SPENDING is (`spreadSuppliers`, the one filter here about what the agent rests on rather tha

How one agent’s record has moved: dealings, independent payers, concentration and delivery, day by day. PAID, one cent a call over x402 — the median price of this rail. Without payment the tool answers with the price and how to pay it, and the free check remains available. The history begins the day we started keeping it; it is a record we keep, not one the chain gives away. WHY readOnlyHint IS fa

What depositors actually KEPT, against what their vault advertised. READ `population` BEFORE QUOTING ANY SHARE FROM THIS. The comparison covers only the vaults where we hold BOTH an advertised rate and a realised one, which is a narrow and lopsided set, usually dominated by one venue: `population.largestVenue` names it and `population.concentration` says how much of the set it is. A share from her

What moved in the agent record, across every agent, since a date. The counterparty check answers what is true about one address NOW; this answers what changed, for all of them, which is the question anybody holding a list asks next. One row per FIELD that moved, not per address: an agent whose dealings and concentration both moved is two facts, and folding them would make you diff the answer to wo

Check up to fifty addresses in one call, each with its observations, AND what the set shares underneath: the parties that two or more of them pay. That second part is the one answer no per-address row can contain, because the input is your own shortlist — four agents stopping together because they all pay one party is invisible in four separate clean records. PAID two ways and they buy different t

If your firm relies on several external agents, what do they rest on AT ONCE? Give it two to twenty-five addresses and it finds the parties more than one of them pays. THE PRODUCT IS THE DISTINCTION, NOT THE JOIN: finding that three agents paid the same address tells you almost nothing — on our rails one address is paid by 71 agents across 4,100 payments and another by three agents once each, and

Does this agent have a BUSINESS, and can any of it be demonstrated? Six questions an investor, a marketplace or an operator actually asks, each answered separately: are the addresses paying it really independent customers; is revenue growing or shrinking; how much is repeat custom; how many of those payments can be shown to have bought anything; what does it cost to run and to whom; and if it has

One agent, four readings, in the order a buyer actually asks them: what it EARNS and from whom, whether its contracted work FINISHED and who signed it off, who it RESTS ON as a supplier, and whether it is still TRADING and its endpoints answer. Every other tool here answers one of those; this is the one that answers them together, over the same nightly record, so the four cannot disagree with each

Before you put capital in, ask what evidence there is that you could get a PARTICULAR amount back out. Every other reading about a vault is about return or about risk of loss; this is about the practical question a holder has, and it is always about a size: "can I get out" has no answer, "can I get $2m out of a vault with $400k free and 25,941 settled withdrawals behind it" has several. Six readin

CALL THIS BEFORE YOUR AGENT SIGNS ANYTHING THAT MOVES MONEY. One request instead of five: it reads the counterparty record, decodes the calldata you are about to sign, looks up the seller’s own catalogue listing, runs an unpaid 402 handshake with the endpoint, and applies a published policy — and then, which is the point, compares them WITH EACH OTHER. The losses an agent actually suffers live bet

Call this with the CALLDATA you are about to sign, before you sign it. Every other check here asks whether an address is worth dealing with; this asks whether the transaction is the one you think it is, and the two catch different losses. No amount of reputation makes the recipient in the bytes match the recipient on your screen, and a spotless counterparty record says nothing about an UNLIMITED A

Call this AFTER you have paid an address or called a tool, to put what you did on the record. Until now this platform answered "should I" and never heard what happened, which is the difference between a lookup and a control layer: a receipt lets the next question about this subject be asked against a record instead of a guess, and lets a verdict we gave be read back against what followed. `referen

Ask to be told when the answer about an address CHANGES. The dimensions are the ones the counterparty check already answers, so this is that same reading on a schedule rather than a second opinion; what it adds is the comparison. The first run records a reading and reports nothing — there is nothing yet to compare against, and a first reading dressed up as news is the thing this avoids. Idempotent
