Your agent got blocked at checkout. Hand us the payment.
Some vendors only take checks. Some want a card number read over the phone. Some sites block every bot on principle. Duckbill is the fallback for the payments your agent can’t complete on its own, online or off.

Half the real world doesn’t take agentic payments.
The contractor wants a check.
The deposit is card-in-person only. The county office takes money orders. We pay it and send the receipt.
The caterer wants a card number read to a person.
The medical bill, the box office, the deposit that can’t wait. Card number read out, confirmation number read back.
The site rejected your agent’s session on principle.
The order still gets placed, and your user still gets the confirmation.
A fallback, not a replacement.
Your agent tries its own rails.
Agentic checkout, virtual cards, whatever you’ve built. Most payments never reach us.
When it can’t, it hands us the payment.
One request: what to pay, who to pay, and the ceiling. Duckbill picks the method that works for that payee.
We complete it and send the receipt.
Amount, method used, confirmation number, and a short summary, as structured data on your webhook.
Built for handing over money.
Tied to a task.
Every payment belongs to a goal your agent sent. Nothing moves on its own.
Capped at the amount you set.
The ceiling is part of the request. We don’t exceed it.
Receipted, every time.
Amount, method, confirmation number, summary. On your webhook.
Questions
Can an AI agent pay a vendor that doesn't take online payments?
Yes. Your agent sends the payment to Duckbill with the payee, the amount ceiling, and the goal. Duckbill completes it by phone, by check, or in person, and returns the receipt as structured data.
What is a payment fallback for AI agents?
The path a payment takes when agentic checkout can't finish: the vendor has no online option, wants a card read over the phone, or blocks automated sessions. Duckbill is that path.
Which payments can Duckbill make?
Deposits, invoices, bills, and orders. By phone, by check, or in person. If the vendor takes money at all, there is a way to pay them.
How do I know what was paid?
Every payment comes back with the amount, the method used, a receipt or confirmation number, and a short summary, on your webhook.
When is the payments API available?
It is in early access. Request access and we will reach out with timing for your use case.
How does pricing work?
A per-task fee on top of the amount paid. Tell us your expected volume and we will send pricing.
