## How to choose

- Fees on small payments: Check the fees on each charge, payout and metered unit, since a percentage fee on small agent payments can outweigh the value of the call itself.
- Rails for agent payments: Check which rails the platform supports, such as cards, stablecoins and bank transfers, since an agent can only pay on rails it can reach by itself.
- Settlement time for payouts: Check how long settlement takes for payments and payouts, since the time between a charge and usable funds affects what an agent can spend next.
- Actions without a person: Check which steps, such as approvals, refunds and payouts, need a person in the loop, since any step that does will stall an agent running unattended.
