Use with the SDK

Install @pipeworx/sdk to call tools from any TypeScript/Node project.

TypeScript
import { Pipeworx } from '@pipeworx/sdk';
const px = new Pipeworx();
const result = await px.call("point_elevation", {});
ask_pipeworx
// Or ask in plain English:
const answer = await px.ask("opentopography — point elevation lookups, dem rasters, and dataset catalog for global terrain data");
