BuiltByEcho Research

Use @builtbyecho/research for local-first web research workflows: search, fetch, render JavaScript-heavy pages, crawl sites, extract structured fields, audit sources, save traces, and produce citation-backed reports.

Install or run

Prefer npx when you only need a one-off run:

npx @builtbyecho/research --help

For repeated use, install globally:

npm install -g @builtbyecho/research
builtbyecho-research --help

Alias:

echo-research --help

Requires Node.js 20+.

Optional browser setup

The package uses Playwright for render/browser escalation. If Playwright browsers are missing, install Chromium:

npx playwright install chromium

Optional search key

No API key is required. For better search discovery, set a Brave API key:

export BRAVE_API_KEY="..."

Without BRAVE_API_KEY, search falls back to DuckDuckGo HTML scraping.

Common commands

Search:

npx @builtbyecho/research search "open source deep research agents" -n 8

Fetch a page:

npx @builtbyecho/research fetch https://example.com --max-chars 5000

Render a JavaScript-heavy page:

npx @builtbyecho/research render https://example.com

Run a research pipeline:

npx @builtbyecho/research pipeline "research agent architecture" --expand --rounds 2 -n 8 --format markdown --trace

Generate a citation-backed report:

npx @builtbyecho/research report "Playwright browser automation best practices" -n 6 --rounds 2 --trace

Extract structured fields:

npx @builtbyecho/research extract https://example.com --schema links,headings
npx @builtbyecho/research extract https://company.example --schema emails,phones,pricing,contact_links,socials

Crawl a site:

npx @builtbyecho/research crawl https://docs.example.com --depth 2 --max-pages 25 --chunk

Workflow guidance

1. Start with search, pipeline, or report depending on the user’s goal.
2. Use --trace for research that may need auditability or follow-up.
3. Prefer render or browser escalation for pages with low text, heavy JavaScript, “enable JavaScript” messages, or bot-wall/CAPTCHA-like content.
4. Treat generated prose as a first draft. Verify citations before high-stakes use.
5. Do not bypass CAPTCHA, login walls, paywalls, robots/ToS restrictions, or other access controls.

Library API

For Node.js code:

import {
  researchPipeline,
  iterativeResearchPipeline,
  toResearchReport,
  extractSchemaFromUrl,
} from '@builtbyecho/research';

const result = await iterativeResearchPipeline('Playwright MCP best practices', {
  expand: true,
  count: 6,
  rounds: 2,
});

console.log(toResearchReport(result));

Vaultline integration

For research that needs durable handoff, upload the final report or trace bundle to Vaultline instead of leaving it in transient chat history.

node -e '
const fs = require("node:fs");
const { Vaultline } = require("@builtbyecho/vaultline-sdk");
const reportPath = "report.md";
const content = fs.readFileSync(reportPath, "utf8");
const vault = new Vaultline({ apiKey: process.env.VAULTLINE_API_KEY });
vault.files.upload({
  path: `research/${Date.now()}-report.md`,
  content,
  contentType: "text/markdown"
}).then(r => console.log("Vaultline fileId:", r.fileId));
'

Use this pattern when multiple agents or human reviewers need the same source-backed artifact.
