Pick a paid tool for your agent

The ranking shows which paid tools AI agents keep paying for, by the money that counted in the 30 days to 9 Nov 2026. Read a category's table column by column, then open the seller's own page.

1. Start with the category

Each category, such as web search, data or AI models, has its own ranking. Pick yours on Categories, or compare several on Explore.

2. Read the row

• Spent in 30 days is what agents paid the tool, counted. It's demand, not revenue.
• Buyers is how many different accounts paid. Many buyers means many agents chose it; a tool with a few big buyers can rank high on money alone.
• Buyer spread splits the money into tenths: the biggest buyer, buyers 2 to 10, and everyone else. A bar that's mostly one buyer means the tool depends on one customer, and the "1 buyer: 97%" label says so in numbers.
• Paid calls is how often agents called it.
• Typical price per call is the middle price agents paid, so you can compare cost between tools that do the same job.
• Change is the places gained or lost since last week; "new" means it wasn't ranked the week before.

3. Open the seller's page

It shows the tool's money, buyers and rank week by week, the accounts it's paid to, and a ✓ with the seller's own line if it claimed its listing. A long run on the chart says more than one strong week.

4. Look over a longer period

On Explore, switch to 3 months or All, or to one chain, to see whether a tool holds its place.

Let your agent ask us

An agent can read this ranking without a browser. Our MCP server at https://agents.agentcharts.xyz/mcp answerscategories, best_tools and seller for free, and the same answers sit behind an x402 endpoint at https://agents.agentcharts.xyz/v1/ for $0.01 a query, for agents that pay as they go. The details are in agent.json.

What the ranking can't tell you

It counts what agents paid, not how good a tool is. It doesn't test quality, speed or uptime, and it leaves out free tools and card payments. Nobody can pay for a place in it. Try a tool on a few calls of your own before you build on it.
