CCGP Government Procurement Search

L0: One-Sentence Summary

Input a company name (short name recommended, e.g. "华为" instead of the full legal name), search ccgp.gov.cn via Kimi WebBridge browser automation, and return a structured list of procurement announcements.

L1: Overview

• Data source: China Government Procurement search (search.ccgp.gov.cn)
• Auth: none (public search)
• Invocation: Kimi WebBridge browser automation (navigate + evaluate)
• Prerequisites: Kimi WebBridge daemon running (127.0.0.1:10086) + browser extension connected
• Key advantage: a browser session naturally avoids the IP throttling applied to direct curl calls

L2: Procedure

1. Check the WebBridge daemon

curl -s -X POST "http://127.0.0.1:10086/command" \
  -H "Content-Type: application/json" \
  -d '{"action":"list_tabs","session":"ccgp-query"}' --max-time 10

If unreachable, start the daemon:

~/.kimi-webbridge/bin/kimi-webbridge.exe start

2. Navigate to the search results page

Windows approach (write JSON to a temp file to avoid encoding issues):

Write C:\tmp\ccgp-nav.json:

{
  "action": "navigate",
  "args": {
    "url": "https://search.ccgp.gov.cn/bxsearch?searchtype=1&page_index=1&bidSort=0&pinMu=0&bidType=0&dbselect=bidx&kw={company-short-name-URL-encoded}",
    "newTab": true,
    "group_title": "政府采购网查询"
  },
  "session": "ccgp-query"
}

curl.exe -s -X POST "http://127.0.0.1:10086/command" \
  -H "Content-Type: application/json" \
  --data-binary "@C:\tmp\ccgp-nav.json" --max-time 30

Wait 5 seconds before continuing.

3. Extract the announcement list

Write C:\tmp\ccgp-extract.json:

{
  "action": "evaluate",
  "args": {
    "code": "(function(){var txt=document.body.innerText||'';var total=(txt.match(/共找到\\s*(\\d+)\\s*条/)||[])[1]||'?';var items=[];document.querySelectorAll('a').forEach(function(a){var t=(a.innerText||'').replace(/\\s+/g,' ').trim();if(t.includes('{company-keyword}')&&t.length>10){var li=a.closest('li')||a.closest('div');var date='';if(li){var m=(li.innerText||'').match(/\\d{4}[-:]\\d{2}[-:]\\d{2}/);if(m)date=m[0];}items.push({title:t.slice(0,80),href:(a.href||'').slice(0,100),date:date});}});return JSON.stringify({total:total,count:items.length,items:items.slice(0,10)});})()"
  },
  "session": "ccgp-query"
}
