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 several addresses, can the link be DEMONSTRATED or is it an unconfirmed assumption. Measured on two live agents: one takes $2,388 a month from 4,772 payers of whom 97% are repeat, the other $932,414 from 7,220 payers of whom 12% are — two completely different businesses that a counterparty count reports identically. THERE IS NO SCORE over the six, deliberately: a number would average "thousands of addresses paid this" against "we hold no delivery record at all", and the second is a statement about US. Four things the data invites and this refuses: an ADDRESS is not a customer (one customer can hold twenty); a PAYMENT is not a delivery (the busiest agents settle on rails that carry money without carrying a job, so "no delivery record" there is our reach and not a finding); a SHARED FUNDER is not an identity (an exchange funds thousands of strangers), so a link is published as demonstrated or as merely co-occurring and the second is never promoted; and a COST we cannot see is not a cost that is not there. PAID. SINCE 2026-10-11 IT ALSO CARRIES economicChain: the four links of the chain an agent has to complete to be a working economic subject — a customer paid it, it ordered or did work, the result was demonstrably delivered, a customer came back. Each link is evidenced, unevidenced (we read the rail and found nothing — a statement about the agent), unread (THE RAIL RECORDS IT AND WE DO NOT READ IT — a statement about us, and the only one of the four that closes by our building something) or unevidenceable (the rail does not record it at all, so no reading by anybody will change it — a statement about the rail). Those three silences are never folded together, because they call for three different acts. Masumi settles work through an escrow whose release or refund is on chain, and SINCE 2026-10-11 WE READ IT: a release to the seller is the buyer letting the escrow go, which is the closest thing to an accepted delivery this chain can show, and it counts alongside an ACP completion. A CLOSURE does not count — over all 29,088 settled escrows, 5,819 refunded to the BUYER against 4,659 released, so counting closures would publish a refund as delivered work more often than not. An agent whose escrows the step reader has not walked yet is unread rather than unevidenced, per agent, because the chain carries the answer and we have not asked for that one. THE FOURTH STATE is the one to read carefully: x402 is 91% of the volume and records payment, never delivery, so for an x402-only agent link three is unevidenceable and reporting it as missing would blame the agent for the rail. NO SCORE: the worst link governs, because averaging lets a strong payment record carry an absent delivery record. Measured over all 3,135 addresses we hold: paid 3,048, hires 432, delivered 684, returned 2,412, and 185 with all four.
