d2b-notice-search

Read-only D2B(국방전자조달시스템) bid notice lookup recipe and parsing helpers for the d2b-notice-search k-skill.

Source

• Official entry point: https://www.d2b.go.kr/index.do
• Public search surface: the rendered 입찰공고 search form on the D2B home page
• Direct HTTP probe: /openapi/sealedBidAnnounceList.json is best-effort only; observed security routing can return 400 Bad Request HTML instead of JSON.

This skill is unauthenticated lookup guidance. It does not log in, bid, submit documents, sign certificates, pay fees, or bypass security software.

Usage

const { buildBrowserAutomationInstructions, buildSearchRequest, parseListHtml } = require("d2b-notice-search")

const recipe = buildBrowserAutomationInstructions({
  keyword: "냉난방기",
  kind: "물품",
  noticeType: "긴급공고",
  dateType: "공고일자",
  dateStart: "2026-07-01",
  dateEnd: "2026-08-30"
})

console.log(recipe.steps)

Returned helpers

• normalizeSearchOptions(input): normalizes Korean/English aliases, dates, and page numbers.
• buildSearchRequest(input): returns the official D2B entry URL, browser form selectors, and best-effort direct request metadata.
• buildBrowserAutomationInstructions(input): documents the fallback order: Aside Browser, BrowserOS CDP/local browser, then direct HTTP best-effort.
• parseListHtml(html): extracts rendered notice links with JavaScript action metadata.
• classifyUpstreamHtml(html): classifies security/login/400 HTML as blocked rather than empty results.

Boundaries

• Primary execution should use Aside Browser against the official rendered page.
• A user-launched BrowserOS session over CDP (or a local browser you own) is the fallback when Aside Browser is unavailable.
• Direct HTTP is not the primary path because D2B security routing may reject non-browser requests.
• No k-skill-proxy route is used because the discovered public search surface does not require an API key.
