Let an agent make purchases from a pre-funded balance
A commenter's agent completed a purchase from a pre-funded balance, buying an $18 gift card to cover a $17.73 order.
Done with a custom-built or unnamed agent
- What they did
- A commenter said Muse handled the shopping run itself. Their first attempt used the normal card path, but checkout stalled when the bank triggered 3-D Secure, which the unattended agent could not complete; using a pre-funded balance instead, the agent bought an $18 gift card to pay for a $17.73 order.
- How it went
- The pre-funded-balance flow completed autonomously, and the card on file was charged $0.00. The reported weak points were not the purchase logic but checkout blockers like 3-D Secure, login walls, and CAPTCHAs.
- Worth knowing
- The main catch was that card payments broke on 3-D Secure, and login walls or CAPTCHAs can stop the run before payment regardless of method.
Try it yourself with ChatGPT Agent
I've pre-funded [account or balance name] with [amount]. Find [item to buy] from [site or store] at the best price within that balance, and get everything ready for checkout. If the exact total doesn't match the balance, tell me about options such as a gift card. Pause before any payment and show me the item, total, and shipping address for my approval.
