How to keep your AI agent's phone calls on a budget

By the CallForMe team at Great Work LLC · Updated Oct 3, 2026 · 3 min read

Short answer: CallForMe runs on a prepaid balance, so your agent never has your card and can't spend more than you've added. Each answered call is $1 for the first 5 minutes, then $0.25 a minute, capped at 30 minutes ($7.25). You can turn auto-reload off, set a spend limit on a batch, and give the assistant hard limits on what it agrees to.

Your agent spends credit, not your card

You add money once, on a Stripe checkout page, and your agent places calls against that balance. What the agent holds is an account key. It can dial and read results; it can't see your card number, raise your balance on its own, or move money anywhere.

The first top-up is $10, about 10 calls. Credit never expires, and you can get unused credit refunded within 90 days of buying it.

Decide how the balance refills

Auto-reload adds $10 when your balance drops below a trigger you pick: $2, $5 (the default), $10 or $20. It's there so a long call around doesn't stall halfway through.

If you'd rather approve every top-up, turn it off on the account page or on the setup page before you pay. Then when credit runs low, your agent shows you a link and waits; nothing is charged until you open it.

Every call has a ceiling

A call ends at 30 minutes no matter what, so the worst case for one call is $7.25. Your agent can end any call sooner with hang_up, and get_call shows how long it has been running.

Long hold queues are where calls get expensive. If you only need a person, use transfer_to: the assistant waits through the hold and connects you when someone picks up. See have an AI wait on hold and patch you in.

Limits on batches

When your agent calls many places at once with call_around:

• max_spend_usd stops dialing new places once the batch has cost that much. Calls already on the line finish, so set it a dollar or two under your real limit.
• stop_after stops once that many calls succeed. 1 means "the first place that can do it".
• A preview first. For more than 10 places, your agent shows you the list and the estimated cost and dials only after you say yes.
• stop_batch ends a batch the moment you have what you need.

Limits on what the assistant agrees to

Money on a call isn't only what the call costs. A business can quote a fee, ask for a deposit, or offer an upgrade. Two fields keep that in check:

• constraints are hard limits: "Don't agree to anything over $200", "Quotes only, don't book". The assistant won't cross them.
• if_asked pre-approves the small stuff so the call doesn't stall: "A deposit up to $25 is fine."

The assistant never reads out card numbers, security codes or passwords, whatever is in the request. If paying is part of the errand, it tells the business you'll handle it directly.

Free ways to check before you spend

• plan_call previews a call without dialing: the opening line, what the business will probably ask, whether it's open now, and the cost.
• find_business looks up numbers and hours.
• Demo lines let your agent rehearse on fictional businesses for free: a pizza place, three auto shops and a gym. See the demo lines.

The full price list is on the pricing page, and the rules the assistant follows on every call are in safety and disclosure.
