# LightFlow JSON Extract
Use `lightflow.json_extract` to extract a JSON value by dot path. Array indexes are numeric path segments.
## Workflow
- Workflow id: `lightflow.json_extract`
- Runtime ownership: this workflow crate owns its public `execute()` entry and exposes it through the `lightflow-json-extract-runner` package binary.
- Host engine: `package.command.v1`; discovery, help, and plan do not execute package source.
- Input values are validated against their declared JSON types without string coercion.
- Runtime: `lightflow.json.extract`.
- Input `value`: required source JSON; widget `json`.
- Input `path`: required dot path, for example `user.name` or `items.0.title`.
- Outputs `value`, `text`, and `found`.
## Usage
```bash
lfw run lightflow.json_extract -i value='{"user":{"name":"Ada"}}' -i path=user.name
```
## API Usage
Start `lfw serve`, then call the workflow through the shared HTTP run contract. Adjust `inputs` to match the workflow contract above.
```bash
curl -sS -X POST http://127.0.0.1:5174/workflows/lightflow.json_extract/run \
-H 'content-type: application/json' \
-d '{"inputs":{}}'
```
