openclaw skills install @apiclaw/web-extractExtract structured JSON from web pages, search engines, and entire sites in ONE call — {title, summary, sections, key_metrics, outgoing_links, author, date, page_type, ...} fields, no second LLM pass to parse HTML. Six endpoints: scrape (single URL), scrape-interactive (JS-rendered pages with click/scroll/type), search (Google SERP + deep-scrape), map (URL discovery), crawl + crawl-status (async recursive crawl). Markdown/raw HTML on request. USE when the user needs page DATA — product pricing/specs, article fields, link graphs, JS-heavy SPAs, Google results with content. Prefer over browser-act (automation/screenshots) and WebFetch (static, no JS, no structured fields). Not for citation-rich research (use deep-research). Trigger (EN): scrape this URL, extract data from page, crawl this site, deep-scrape search results, map a domain's URLs, render this JS page. 触发词:抓取/爬取/网页提取/结构化抽取/搜索带内容/全站爬取/JS 渲染抓取/点击后抓取. Requires ZOODATA_API_KEY (free key: https://zoodata.ai/en/api-keys).
openclaw skills install @apiclaw/web-extractBacked by the ZooData WebTools API. Six HTTP endpoints. One API key. Structured JSON by default — no second LLM pass to parse fields.
| File | Purpose |
|---|---|
{skill_base_dir}/scripts/webtools.py | Thin CLI wrapper — one subcommand per endpoint. Has the Cloudflare-UA, crawl-warmup, and nested-data-shape quirks baked in. Run --help for params. |
{skill_base_dir}/references/reference.md | Full request/response schemas, error codes, billing, edge cases. Load when you need exact field names. |
| Tool | What it gives you | When to pick it |
|---|---|---|
web-extract (this skill) | Page → {title, summary, sections, key_metrics, outgoing_links, ...} JSON in one call | You need page DATA (price, specs, fields, link graphs) — downstream code or LLM can use the JSON directly without re-parsing |
browser-act | Browser session: click, scroll, type, screenshot | You need to interact with a page (login flow, take a screenshot, fill a form) or visually verify rendering |
WebFetch (built-in) | Static URL → markdown | You need a single static page as prose, no JS rendering, no structured fields |
deep-research | Multi-source research with citations | You need a synthesized report drawing from many web sources, not raw data |
monid | Generic tool-discovery layer | You're not sure which tool to use yet and want to browse options |
Key advantage: every other tool above forces a second pass (re-LLM the markdown / re-parse the HTML / extract structure manually). The underlying API returns the structured fields directly — saves a round-trip and tokens.
Required: ZOODATA_API_KEY (legacy APICLAW_API_KEY still works as fallback).

webtools.py CLI (preferred — quirks baked in): UA header, warmup tolerance, retry/backoff, JSON-first defaults all handled. Just run python {skill_base_dir}/scripts/webtools.py <subcommand>.User-Agent: web-extract-skill/1.0 — the Cloudflare edge rejects the default Python-urllib UA with HTTP 403 (see Tips).Endpoint base URL: https://api.zoodata.ai/openapi/v2/webtools/*. All POST with JSON body, except crawl/{id} (GET).
This skill defaults to formats: ["json"] for every scrape / scrape-interactive / search-with-scrapeOptions call. The API itself defaults to ["markdown"], but JSON gives the agent structured fields (title, summary, sections, key_metrics, outgoing_links, page_type, …) that compose better with downstream tools and are usually smaller to put back into context.
Switch to markdown only when the user explicitly asks for "the article text" / "clean prose" / "as markdown", or when the page is genuinely article-shaped (long-form blog post / news / docs) and structured fields wouldn't help. Switch to rawHtml only when the user needs DOM access (custom CSS selector extraction, table parsing the API didn't structure, embedded <script> data, etc.). Request multiple formats in one call (["json","markdown"]) when you genuinely need both — but never silently fall back to markdown when the user didn't ask for it.
| User intent | Endpoint | Cost |
|---|---|---|
| Fetch one URL as structured JSON (default) | POST /scrape formats:["json"] | 1 credit |
| Fetch one URL as markdown (user explicitly asked) | POST /scrape formats:["markdown"] | 1 credit |
| Fetch one URL as raw HTML (user needs DOM) | POST /scrape formats:["rawHtml"] | 1 credit |
| Same as above, but page needs JS / login / click-through / scroll | POST /scrape-interactive | 1 credit |
| Google search → list of result URLs | POST /search (SERP-only) | 1 credit |
| Google search → URLs + structured JSON for each | POST /search scrapeOptions:{format:"json"} | 1 credit per returned result |
| List all URLs reachable from a website | POST /map | 1 credit |
| Recursively pull every page of a site (async) | POST /crawl + GET /crawl/{id} poll loop | 1/submit + 1/poll |

# 1. Scrape one URL as structured JSON (default)
$WT scrape https://example.com
# → data.json = {title, summary, sections, key_metrics, outgoing_links, author, date, page_type, ...}
# 2. Scrape as markdown (user explicitly asked for prose)
$WT scrape https://example.com --format markdown
# 3. Need BOTH JSON and markdown in one call
$WT scrape https://example.com --format json --format markdown
# 4. JS-heavy page — wait, click "Load more", scrape
$WT interactive https://example.com --actions '[
{"type":"wait","milliseconds":1500},
{"type":"click","selector":"button.load-more"},
{"type":"wait","milliseconds":1000}
]'
# 5. SERP-only search (cheap — 1 credit total, regardless of result count)
$WT search "best wireless earbuds 2026" --limit 10
# 6. Deep-scrape every search result as JSON (1 credit per result)
$WT search "best wireless earbuds 2026" --limit 5 --deep-scrape
# 7. Search restricted to specific domains, last 24h
$WT search "python async" --limit 20 --tbs qdr:d \
--include-domains "python.org,realpython.com"
# 8. Discover every URL on a docs site under /api/
$WT map https://docs.example.com --include-paths "/api/.*" --limit 1000
# 9. Crawl + poll in one shot (handles warmup, paginates pages internally)
$WT crawl-wait https://blog.example.com --limit 200 --max-depth 3 \
--poll-interval 10 --max-wait 1800
# 9b. Or submit + manual poll
$WT crawl https://blog.example.com --limit 200 --max-depth 3

Run $WT <subcommand> --help for every flag on any subcommand.
When the CLI isn't available (no python3 / offline / restricted env), every endpoint also takes a plain JSON POST:
curl -sS -X POST https://api.zoodata.ai/openapi/v2/webtools/scrape \
-H "Authorization: Bearer $ZOODATA_API_KEY" \
-H "Content-Type: application/json" \
-H "User-Agent: web-extract-skill/1.0" `# REQUIRED — see Tips` \
-d '{"url":"https://example.com","formats":["json"]}'
See references/reference.md for the full JSON body shape of every endpoint. Any non-curl HTTP client must set a custom User-Agent header — Cloudflare's edge blocks the default Python-urllib UA with HTTP 403 (error code 1010).
Full schemas are in references/reference.md. Load that when you need exact field names or are debugging.
/scrape: url (required), formats: ["json"|"markdown"|"rawHtml"] — skill default ["json"] (API itself defaults to ["markdown"] if formats omitted; always pass it explicitly). Max 3 formats per call.
/scrape-interactive: url, formats, actions: [...] — 7 action types (wait/click/write/press/scroll/scrape/executeJavascript). Max 50 actions, cumulative wait ≤ 60s.
/search: query (supports inline Google operators), limit (1–20, default 10), sources (["web","news","images"]), tbs (qdr:d|w|m|y), includeDomains/excludeDomains (bare hostnames, max 20 each), scrapeOptions: {format:"markdown"|"json"} (presence triggers deep-scrape).
/map: url, limit (1–100000, default 5000), search (keyword rank filter), sitemapMode (include/only/skip), includeSubdomains (default true), includePaths/excludePaths (regex), ignoreQueryParameters (default true).
/crawl: url, limit (1–10000, default 100), maxDepth (1–10), includePaths/excludePaths, allowSubdomains, sitemapMode, ignoreQueryParameters (default false — opposite of /map), crawlEntireDomain.
GET /crawl/{job_id}: query params skip, limit (1–1000). data is an array of page-scrape blobs. meta.total is the running total; compare against data.length to detect completion.
api.zoodata.ai blocks default Python Python-urllib/X.Y User-Agent → HTTP 403. ALWAYS set an explicit User-Agent header (any non-default value works, e.g. User-Agent: web-extract-skill/1.0). curl is fine out of the box; Python / Go / Node fetch / requests all need it.GET /crawl/{job_id} warmup gotcha: for ~5–10 seconds after POST /crawl returns the job_id, polling may return NOT_FOUND. This is the job still registering, not a real "not found." Tolerate it: retry with 5s sleep up to ~3 times before giving up.crawl-status response shape: data is an object {id, status, completed, total, data: [pages...]} — the page array is nested at data.data. Status values: "queued", "running", "completed", "failed". (Failed success:false responses cost 0 credits.)success:true response can still contain an error page. Always check data.meta.statusCode (or per-result meta.statusCode for search) before trusting content./search may return fewer than limit results — pages with no extractable content in the chosen format are dropped.https://github.com or github.com/path → 422. Use github.com.includePaths / excludePaths are regex, not glob. Use /blog/.* not /blog/**.ACCESS_DENIED, RATE_LIMITED) are NOT billed. TIMEOUT and CONTENT_UNAVAILABLE are.limit=1000 and space polls ≥10s apart.json is the default — gives structured fields (title/summary/sections/key_metrics/outgoing_links/page_type/...) that downstream tools can consume directly. Use markdown only when the user asks for clean prose or the page is article-shaped (blog post / docs); use rawHtml only when DOM access is needed (custom selectors, table parsing the JSON layer doesn't expose).BEFORE calling any endpoint, verify a credential is configured. Reliable check: python {skill_base_dir}/scripts/webtools.py check — exits 2 if no key is found in env (ZOODATA_API_KEY / legacy APICLAW_API_KEY) or config files (~/.zoodata/config.json / ~/.apiclaw/config.json). A [ -z "$ZOODATA_API_KEY" ] test alone is NOT sufficient.
When no key is found through any mechanism:
