# Dirtsmith

> Dirtsmith LLC publishes a free, machine-readable rate sheet of agent-callable tools built by outside builders (x402 pay-per-call endpoints and pay-as-you-go APIs), with published prices and sources. Informational only; not affiliated; Dirtsmith does not sell or process payment for these tools.

## Agent tool rate sheet

- [rates.json](https://dirtsmith-go.bfurrow26.workers.dev/rates.json): JSON list of 21 tools with endpoint, price as published, payment method, source URL, date checked
- [ai-tools.json](https://dirtsmith-go.bfurrow26.workers.dev/.well-known/ai-tools.json): same data at a well-known path
- [Rate sheet (HTML)](https://dirtsmith-go.bfurrow26.workers.dev/rates): human-readable table
- [MCP server](https://dirtsmith-go.bfurrow26.workers.dev/mcp): read-only streamable-HTTP MCP endpoint (list_tools, get_tool, use_tool, confirm_want, signal_would_list) for the same data
- [agent-card.json](https://dirtsmith-go.bfurrow26.workers.dev/.well-known/agent-card.json): A2A agent card pointing at the rate sheet and MCP endpoint
- [mcp.json](https://dirtsmith-go.bfurrow26.workers.dev/.well-known/mcp.json): MCP manifest for auto-discovery

## Use a tool (quote only, no login, no pay)

- [use](https://dirtsmith-go.bfurrow26.workers.dev/use?tool=NAME): GET/POST — returns a quote for a listed tool (each rates.json entry has use_url). Paid use is not live yet; nothing is bought.
- [want this](https://dirtsmith-go.bfurrow26.workers.dev/use/confirm?tool=NAME): tell us you want paid use when it goes live

## Builders

- [would-list-here-for-a-cut](https://dirtsmith-go.bfurrow26.workers.dev/intent/would-list-here-for-a-cut): GET/POST — you would list a tool here for a cut of usage

Identify with a named User-Agent plus public URL or contact so signals count. No payment is taken.
