It acts
Agents use tools, not screens
They call APIs, read and write to business systems and talk to other agents directly. A website built for humans is an obstacle to them, not an interface
Agent Pay
AI agents are starting to pay. Changelly makes sure the money arrives in the right asset, on the right chain.
An agent pays with whatever its wallet holds. The business on the other side wants a specific stablecoin, on a specific chain, at a price it can book. Changelly is the conversion and settlement layer that closes that gap, in one API call.

First · What an AI agent is
Software that is given a goal, not a script, and works out the steps itself
A chatbot answers a question. An agent is handed an outcome ("restock the warehouse", "settle this month's invoices", "find and book the cheapest route") and then plans, calls other systems, checks results and keeps going until the job is done, with a human setting limits rather than clicking every step
It runs alone
Agents work without a person present
Tasks run overnight, in bulk, or in milliseconds. Whatever an agent needs to finish a job has to be available without a human approving each step
It spends
Finishing most jobs means paying someone
Buying goods, paying a supplier, purchasing data or compute. Once agents do real work, they need a way to move money that is as automatic as the rest of what they do
Then · How agents pay
Agents don't use a checkout page. They hold a mandate and call an API.
Open standards now define how an AI agent is allowed to spend. Google's AP2 proves what the user approved, OpenAI's ACP hands a cart to a payment token, and Coinbase's x402 lets an agent pay over HTTP in stablecoins. In every case the agent ends up with the same thing: an instruction to pay a payee a fixed amount.
AuthorizeA user grants the agent a spending mandate
“Buy this, pay that invoice, keep suppliers paid.” The agent gets limits and a signed authority to spend within them
DecideThe agent finds the payee and the price
It negotiates the purchase or receives the invoice, usually machine-to-machine, with no human on the screen
PayThe agent sends a payment from its wallet
Wallet balances are crypto and stablecoins. The payee's address and preferred asset are rarely the same as what the wallet holds
The protocols decide whether an agent may pay. None of them handles what currency arrives, on which chain, at what rate.
≠The wallet holds ETH, SOL or a mix. The payee wants USDT or USDC.
≠The wallet is on one network, the receiving address on another.
±
Price risk.A mandate authorizes an exact amount. The payee must receive exactly that.
If the conversion fails mid-flow, nobody is watching.
Finally · How Changelly helps
One API call converts the agent's payment into exactly what the payee wants.
Changelly plugs in under any agent platform, wallet or commerce system. The agent sends what it has; Changelly delivers what the payee asked for, with the rate locked before anything moves and a receipt the finance team can reconcile.
WITHOUT CHANGELLY
Agent has to find liquidity, bridge chains and manage slippage itself
Payee receives the wrong asset or a different amount than invoiced
Every wallet is a separate counterparty for the payee's risk team
Failed or partial conversions with nobody watching
Agent sends any supported asset; Changelly routes across venues and chains
Payee receives the exact stablecoin amount, at its own address, on its chosen chain
One institutional counterparty on every leg
Locked quote before funds move, settlement receipt after
Any stablecoin, USDT first
Settle into USDT, USDC or whichever stablecoin the payee specifies, from any supported asset on the paying side.
Any chain
Pay from one network, deliver on another. Cross-chain routing happens inside the swap, not in the agent's code.
Delivery to an address
Funds land at the address the payee names. No account to open, no new wallet to adopt.
Locked pre-trade quotes
The amount the agent is authorized to spend is the amount that settles. The rate is fixed before anything moves.
Inbound and outbound
Customers pay in any asset and the business books one. Treasury pays suppliers in theirs. Same engine both directions.
Agent-callable, non-custodial
API-first and ready for x402 and AP2 flows. Changelly never holds the balance; it routes, executes and returns a receipt.
From quote to delivery in four steps
1
Quote
The agent asks Changelly for a locked rate from its asset to the payee's stablecoin and chain.
2
Send
The agent's wallet sends the paying asset to the quoted address.
3
Convert
Changelly sources liquidity across venues and executes the conversion and chain transfer in one step.
4
Deliver
The payee receives the exact amount at its address. A receipt goes back to the agent and the finance system.
