# Examples

URL: https://services.dev/docs/examples

> Whole brands built on services.dev, each proving one layer of the model, file by file.

Each example is a whole brand: its Services, its check, a walk through one job, and its plans. Each proves one layer. lingua proves the AI-only default. api.lawyer proves people and the gate. apis.tax proves time: clocks, kept facts and a plan that runs a year. api.forsale proves money paid on an outcome.

| Brand | Proves | Its gate |
|---|---|---|
| [lingua](https://services.dev/docs/examples/lingua.md) | AI delivers every job alone | [its own suite](https://services.dev/docs/examples/lingua.md#every-branch), over HTTP and MCP |
| [api.lawyer](https://services.dev/docs/examples/legal.md) | credentialed people, parties, and charging on a receipt | [its own suite](https://services.dev/docs/examples/legal.md#its-suite), over HTTP and MCP |
| [apis.tax](https://services.dev/docs/examples/tax.md) | time: clocks, a taxpayer's periods and kept facts, and a plan that runs a year | [the `tick 1y` walk](https://services.dev/docs/examples/tax.md#the-gate) and [its own suite](https://services.dev/docs/examples/tax.md#its-suite), over HTTP and MCP |
| [api.forsale](https://services.dev/docs/examples/sales.md) | an outcome: nothing on effort, 5% of the closed value when the account pays, or 15% with a closer, held for its window | [api.forsale's own suite](https://services.dev/docs/examples/sales/port.md#the-suite) and [the sales kernel's 76 tests](https://services.dev/docs/examples/sales/port.md#its-behavior-tests) |

Every key page in the Service tab shows the lines of these files that use its key, under "In the example brands".
