English pilot — the directory is mainly in French for now.
The honest answer: it depends on the billing model — and there are three of them, each with different traps. Here is how each one works, with orders of magnitude read on the tools' official pages in October 2026.
Most consumer agents are paid like classic software: a fixed price per month, often around $20/month — that's the price of ChatGPT Plus and of Claude Pro, both of which include their agent features (ChatGPT (agent mode), Claude Cowork). Specialized tools run from $0 to $50/month for most profiles in this directory. Advantage: the bill is predictable. Limit: the “included usage” has ceilings, and a very active agent can hit them before the end of the month.
Some services bill what the agent actually consumes. Voice agents are paid by the call minute — figure $0.07 to $0.31/minute all-in with per-minute providers (rates read in October 2026); our profile Synthflow details this market and its traps. More unusual, Intercom Fin bills by outcome: $0.99 per customer request actually resolved. Advantage: you pay for work done. Limit: with no cap, the bill fluctuates — and can surprise you.
Open-source agent software is often free (MIT license, most of the time): you then pay for the model calls the agent consumes, at the provider's rate — from a few dollars a month in light use to far more if the agent runs continuously. Agents that run entirely locally on your machine (Ollama (local agents)) bring that cost down to $0, for the price of a decent machine and a bit of setup. And to keep a grip on the API bill, there are capping tools such as LiteLLM.
Setup time. Even an “easy” agent still takes one to three hours of configuration and testing before you can trust it.
Supervision. Rereading an agent's output is part of the cost — count it in, especially in the first month.
Mistakes. An agent that sends the wrong email or books at the wrong price costs more than its subscription. Hence the guardrails in the guide AI agents: risks and guardrails.
Stacking subscriptions. Five tools at $20 make $100/month: most needs are covered by one or two well-chosen agents.
Choose a billing model and adjust the volume. Rough estimate, as an order of magnitude only: always check the real price on the tool's website before you commit.
Estimate:
Basis (ranges read on the tools' official pricing pages, October 2026): a typical consumer agent subscription ≈ $20/month; an all-in voice call between $0.07 and $0.31/minute; one agent task typically consumes $0.02 to $0.50 worth of API calls depending on the model and the length of the task.
Start with the free plan or the trial, measure the time actually saved over a month, and only pay if the math is obvious. A profitable agent is easy to spot: it saves you, every week, more time than its monthly price is worth in hours of your work.
