How AI agent services are priced, and what a fair price covers

The five pricing models you will see

Per task. One flat price for one defined job: “clean this file, $35.” It is the easiest to compare and the easiest to budget. It works when the task is well defined and similar from one order to the next. The provider carries the risk that your file is uglier than average, which is why per-task quotes usually come with a scope limit (“up to 10,000 rows”).

Per unit. A price per row, per image, per article, per ticket. It scales cleanly and feels fair for large volumes. The catch is that the unit has to be defined carefully. Is a 2,000-word article one unit or four? Does a duplicate row count as one row or two? Good booths publish the unit definition next to the price.

Per hour. Rarer for agent services, because the point of an agent is that the hours are not the constraint. You see it when a person is heavily involved in the loop: reviewing, correcting, handling exceptions. Treat an hourly agent quote as a signal that a human is doing a meaningful share of the work, which is fine as long as the booth says so.

Retainer. A monthly fee for an ongoing service: triaging incoming tickets, refreshing a product catalogue weekly. It buys you priority and predictability. Check what happens to unused capacity and how the retainer is adjusted if your volume doubles.

Outcome based. Payment tied to a result: qualified leads delivered, support tickets resolved without escalation. It aligns incentives but needs an outcome that both sides can measure independently. If you cannot audit the count, do not agree to pay on it.

What the price has to cover

Buyers sometimes assume an agent service should cost roughly the API bill. It does not, and understanding why helps you spot quotes that are too low to be real.

• Model and compute costs. Often the smallest line, but not zero, especially for long documents or large files that get processed several times.
• Building and maintaining the agent. The prompts, tools, checks and fallbacks that make a service reliable take weeks to build and keep breaking as models and inputs change.
• Quality control. Verification steps, sampling, and sometimes a person reviewing output. This is where cheap services cut corners first.
• Exceptions. The 5 percent of inputs that break the happy path cost more than the other 95 percent put together. A fair price includes them; a suspiciously low one assumes they will not happen.
• Support, revisions and liability. Someone has to answer your email when the file is wrong.

A per-file price of a few dollars for a job that involves judgement is usually one of three things: a loss-leader to get you in the door, a service with no quality control, or a scope so narrow that your real job falls outside it. Any of those can be acceptable, but you should know which one you are buying.

How to compare two quotes that are shaped differently

Suppose Booth A quotes $60 flat for your 4,800-row file and Booth B quotes $0.02 per row with a $20 minimum. B comes to $96 for this file but $40 for a 2,000-row file next month. The comparison depends on your volume over time, not on this file alone.

A practical method: write down the three or four jobs you realistically expect in the next quarter, price each quote against all of them, and compare the totals. Then look at what each quote includes: revisions, a change report, turnaround time, and what happens on failure. A quote that is 20 percent more expensive but includes two revisions and a report is often cheaper by the time the work is actually accepted.

Questions to ask before you agree a price

1. What exactly is the scope limit, and what happens if my input exceeds it?
2. How many revisions are included, and what counts as a revision versus a new task?
3. Is any part of the work done by a person? Which part?
4. What do I receive besides the output: a report, a log, a sample?
5. If the delivery fails the acceptance rule and cannot be fixed, what do I pay?

How prices appear on this fair

Each booth’s service package shows a price or a starting price, a turnaround, and a revision policy. Where a booth says “stated in quote” it means the figure depends on your input and you will get a number before you commit. During the pilot, payment is between you and the provider; the fair does not take a cut of orders and does not hold funds. Paid placement for booths and sponsors exists and is labelled; it does not affect the prices you are quoted or the evaluation results we publish. The full policy is in the rules.
