Which side of the money are your agents on?

Nustro is the accountability layer autonomous agents transact on. What your platform builds — and what it earns — depends on one thing: whether your agents are paying, getting paid, or both.

These are positions in a transaction, not types of company. Any platform can serve either or both — and serving both is paid twice.
Your agents paySide 01 · Demand side

Know who your agents are paying, and cap what they can spend

Your principal asks for something and your agent goes and pays a company you have never dealt with. Nustro gives that counterparty a verifiable identity, a track record, and money set aside to make good if it fails — and gives you hard limits on what your agent can commit.

“Book me a flight to Dublin”your principalConsumer agentyourslimitsYour platformverify · routeyou sit herediscoverairlineevery certified provider — onboarded by you or not

Your platform checks the counterparty and enforces your principal’s limits before any money moves, then steps out. The agents settle directly.

This is for you if you runA product where an agent books travel, tickets or reservations for a principal · an assistant that orders, subscribes or pays bills on someone’s behalf · a runtime whose agents buy inference, search and data per call · a procurement suite whose agents source and order from suppliers · a fabric that routes other people’s agents to paid services.
Check before you pay. Every counterparty carries an identity you can verify, a rating computed from its settlements, and escrow you can see.
Hard spending limits. A per-transaction ceiling and a rolling limit, enforced by the network before the payment is authorised — not by your own middleware.
Get money back when it fails. File a dispute and the remedy comes from the counterparty’s escrow. Filing costs your side nothing.
Buy from anyone certified. Your agents reach every provider on the network, not only the ones you signed up yourself.

Your agents get paidSide 02 · Supply side

Get your sellers found by buying agents, and paid without chargebacks

Buying agents have budgets and no way to tell your sellers apart from anyone quoting the same price. Nustro gives each seller a record buyers can check, puts it in front of buying agents on every platform, and settles payments that cannot be reversed after the fact.

your sellersYour platformverify · routecertify · publish cataloglistedthe scheme directoryfound bybuying agents on any platform — they verify without contacting you

Certification lists every seller in the network directory with its catalog, its escrow and its rating — so buying agents anywhere can find it and check it without contacting you.

This is for you if you runA storefront or retail marketplace selling to shopping agents · travel, hospitality or ticketing inventory sold to booking agents · an API, data or inference business charging agents per call · licensed content or research sold to agents that cite it · a monetization gateway fronting many providers for agent traffic.
Proof that travels. A rating computed from real settlements, verifiable by a buyer who has never contacted you — so a good record wins work off your platform, not just on it.
Listed everywhere, once. Certification puts each seller in the network directory with a machine-readable catalog buying platforms can index.
No chargebacks. Payment settles on-chain and cannot be pulled back. Disputes are decided and paid from escrow instead.
Ranked on merit. Discovery anywhere may weigh what an agent is and does — never which platform hosts it.
What you build
RegisterSellers as principals; one agent each.
ConfigureMarkets, wallets, dispute window. Escrow self-funds.
PublishA catalog of offers on each agent.
SupportDispute responses and escrow headroom.
What you earn

You are paid the supply share on every settled transaction — for onboarding sellers, configuring markets and wallets, indexing catalogs and supporting disputes.

You serve both, and match themSide 03 · Both sides

Earn on both sides of every transaction you match

Marketplaces start here, and most platforms end up here. Serving the other side of transactions you already carry is paid twice, and cuts what the network charges on an internal transaction down to the operator fee alone.

YOUR PLATFORMbuyer agentsMatchtrust & fitseller agentsproviders elsewheresupply inbuyers elsewheredemand inboth shares credited to you

You match inside your own venue and reach outside it in both directions — pulling in supply you never onboarded, and putting your sellers in front of buyers you never onboarded.

This is for you if you runA marketplace where agents hire agents for work · a service exchange matching agent demand to agent supply · a vertical marketplace in logistics, legal, creative or research · a platform already serving one side that wants the other side’s revenue.
Paid twice on your own matches. Both shares are credited to you, and an internal transaction costs only the operator fee.
Escrow you do not fund. Sellers back their own promises. You stop being the insurer of your own inventory.
Match on trust, not just fit. Filter by certificate, rating and market before you rank — ranking stays your product.
Supply and demand beyond your own. Reach sellers you never onboarded, and let buyers elsewhere find the sellers you did.
What you build
RegisterAgents on both sides.
ConfigureLimits one side, markets and escrow the other.
DiscoverYour index plus the network directory.
SupportBoth sides of every dispute.
What you earn

You are paid both shares. On a transaction where you serve both sides, the only network cost left is the operator fee.

Why platforms choose Nustro

Checkout has standards. Payments have three. Accountability has Nustro.

Commerce protocols orchestrate the purchase. Payment protocols move the money. Identity registries list the agents. None of them answer the harder questions: what happens when an agent causes financial harm? What is set aside before the transaction begins? How is a dispute settled without a court? Nustro answers them — built on an open specification, so nothing you accumulate is locked to us.

Governance & compliance
Nustro cannot touch your money. It cannot move a seller’s operating funds, cannot refund, cannot transact for anyone. Its reach ends at escrow, and fees are never taken from escrow.
Nothing is locked to us. Identities, ratings and escrow rules come from an open specification — readable by a counterparty that has never contacted Nustro.
Recourse that actually pays out. Disputes are decided and settled from escrow, not negotiated in a support queue — and the party filing never pays to file.
One published price list. The same rates for every platform, with increases on ninety days’ notice and no private deals.
