Stipend is a USDC wallet that an AI agent installs and controls by itself. There is no developer account to open and no API key to paste in. You set the spending limits and the agent cannot raise them. It also keeps a record of what it earns and spends, so you can see whether it is paying for itself.
curl -sL stipend.sh/install | sh
irm stipend.sh/install.ps1 | iexstipend is then not found, add ~/.local/bin to
your PATH.Agents: read /skill.md — it is written for you and you can act on it unaided.
MetaMask, Coinbase and Circle all need a person to open a developer account and set up keys before an agent can use them. That means an agent cannot get a wallet without a human doing the paperwork first.
Stipend is the wallet it can set up on its own.
When your agent meets an API that asks to be paid, it pays and carries on instead of stopping to ask you. It works with any x402 endpoint. x402 is an open standard with roughly 165 million transactions behind it.
It has an address of its own that it can publish, so people and other agents can pay it. Money arrives whether the agent is running or not.
It records what it earned and what it spent, by category, over time. That lets it tell you something like:
"Earned $4.20, spent $6.10. Covering 69% of what I cost to run. 6 days left."
Your agent reads text written by strangers, and some of that text is written to manipulate it. Prompt injection between bots is already happening. The limits below are built on the assumption that your agent will be fooled at some point, and are meant to make that survivable.
| Per transaction | $25 | hard ceiling |
|---|---|---|
| Per day | $100 | rolling total |
| Above $10 | confirm | needs your explicit approval |
| New address | confirm | first payment to any unseen payee, any amount |
| Allowlist | absolute | once set, funds reach nothing else |
The limits are enforced in code, after the agent decides to pay and before the payment is signed. They are not instructions in a prompt, so no wording from anyone can change them. The allowlist is the strongest of them: switch it on and even an agent that has been completely fooled cannot send money to an address you did not name.
We never hold your key. It is generated on your machine, encrypted with a passphrase from your environment, and stored outside the agent's workspace, because an agent's file tools are not reliably confined to that folder.
Because we never see the key, we cannot recover it for you. If you lose both the keystore and the passphrase, the money is gone. Keep the balance small: this is meant to be a working float rather than savings.
The wallet is free. The thing you can pay for is not having to supply ETH, which is what otherwise stops an agent from spending money it has already earned.
Every blockchain transfer costs a network fee, and that fee has to be paid in ETH rather than in the USDC your agent holds. So an agent can be paid all day and still not be able to send anything until somebody buys it ETH. One credit covers the fee on one transfer, and we pay it.
stipend credits buystipend license buyThe free tier is the whole wallet. Your agent creates it and holds the key, pays automatically when a service asks to be paid, and reports what it earned and spent. The limits are checked between deciding and signing, so nothing it reads can talk it into raising them.
The dashboard is the part for you. Everything else your agent reads as JSON and never needs a screen for. The dashboard is a page you open: what it earned, what it spent and on what, whether it is paying for itself yet, and every time its limits refused it.
No fee on what your agent spends or earns. We take nothing from your transactions — credits cover the network fee and nothing else.
Pay from your own wallet. No card, no account, no human.
stipend credits buy --confirm # $7.80, 1,000 credits. Under your $25 cap on purpose.
The $39 pack is not an agent's to buy — it is a dashboard for the
human paying the bills, and it sits above the agent's own cap. Buying it
would mean approving around that limit to pay us. They buy it above;
the agent then runs stipend credits claim <key>.

and the commission covers the $7.80 pack exactly.
The $7.80 pack sits under the default $25 cap on purpose. Our address is new
to your agent like any other address, so the first payment still needs
--confirm — once, ever, and no human. $39 is above the cap, so
it needs an explicit stipend approve first. We could have
exempted our own address and made both sales smoother. We didn't — a limit
with a vendor-shaped hole in it is not a limit.
Your agent probably sent you here. What it is asking for is a wallet with spending limits you control, so it can pay for the small things it needs — API calls, data, tools — without coming back to you every time.
You set the ceilings. Anything above $10 needs your approval. First payment to any new address needs your approval regardless of size. If you turn on the allowlist, money can only ever reach addresses you named.
Read the longer version, or just look at the limits above — they are the whole story.
The wallet is free. If you want to buy the $39 part, it is here — one payment, no subscription, and your agent can pay for it itself if it has funds.
