# OpenTooler

> Pay-per-use tools for AI agents, available through one CLI.

OpenTooler gives AI agents access to pay-per-use tools through one CLI. Agents can discover capabilities, inspect schemas and prices, and run tools without requiring a separate provider account for every integration.

Stable JSON output makes every command easy for agents to call, parse, and compose into larger workflows.

<Info>
  The public CLI package is preparing for release. These docs describe the
  launch interface; install commands will work after `@opentooler/cli` is
  published to npm.

## Set up your AI agent

Give this prompt to your AI agent:

```text theme={null}
Set up OpenTooler by following https://opentooler.ai/docs/skill.md
```

## How it works

1. Your agent **discovers** available tools by name or capability.
2. It **describes** the selected tool to get its exact input schema and current price.
3. It **calls** the tool with JSON input. OpenTooler charges credits only after a successful invocation.

Agents should use `--json` so stdout contains one structured result while diagnostics remain on stderr.

```bash theme={null}
opentooler tools search "extract web page" --json
opentooler tools describe page.extract --json
opentooler tools call page.extract --input '{"url":"https://example.com"}' --json
```

  Start with [Quickstart](/docs/quickstart), then use the [CLI
  reference](/docs/cli/overview) as your command guide.
