# seleniumbase-website-scraper
|
|
|
|
Private A2A agent for compliant, authorized website scraping with SeleniumBase/browser automation where available.
|
|
|
|
## Safety policy
|
|
|
|
Use this agent only for authorized scraping of public or user-owned sites. The agent must not bypass, solve, defeat, or evade CAPTCHAs, anti-bot protections, login gates, paywalls, `robots.txt`, ToS restrictions, or access controls. If a CAPTCHA, anti-bot challenge, login wall, paywall, or access-control indicator is detected, the run stops and returns a manual-intervention/blocked status.
|
|
|
|
The agent does **not** use stealth/undetected-browser modes, CAPTCHA solvers, proxy rotation, credential injection, or access-control circumvention.
|
|
|
|
## Skill
|
|
|
|
### `scrape_website`
|
|
|
|
Inputs:
|
|
|
|
- `url` — absolute `http` or `https` URL.
|
|
- `selectors` — mapping of output field names to CSS selectors.
|
|
- `max_pages` — maximum same-origin pages to visit.
|
|
- `wait_seconds` — wait after page open before capture/extraction.
|
|
- `output_format` — `json` or `csv`.
|
|
- `headless` — toggle browser headless mode.
|
|
- `user_agent` — optional custom single-line user agent.
|
|
- `respect_robots` — when true, checks `robots.txt` before fetch and pagination.
|
|
- `rate_limit_seconds` — polite delay between pagination requests.
|
|
- `screenshot` — save PNG screenshots for visited pages.
|
|
|
|
Outputs:
|
|
|
|
- `status` — `ok`, `invalid_input`, `blocked_by_robots_txt`, `manual_intervention_required`, `browser_runtime_unavailable`, or `error`.
|
|
- `items` — extracted records.
|
|
- `saved_paths` — output files under `outputs/seleniumbase-website-scraper/`.
|
|
- `warnings` — safety, robots, selector, browser, or runtime warnings.
|
|
- `screenshots` — screenshot file paths when requested.
|
|
- `pages_visited` and `html_captures`.
|
|
|
|
## Selector syntax
|
|
|
|
Default extraction returns visible text:
|
|
|
|
```json
|
|
{"title": "h1", "summary": ".article-summary"}
|
|
```
|
|
|
|
Supported suffixes:
|
|
|
|
- `::text` — visible text.
|
|
- `::html` — inner HTML.
|
|
- `::attr(name)` — attribute extraction, e.g. `a.card::attr(href)`.
|
|
|
|
Special pagination selector field names are not emitted as data fields and are used to find the next page:
|
|
|
|
- `next`
|
|
- `_next`
|
|
- `__next__`
|
|
- `pagination_next`
|
|
- `next_page`
|
|
|
|
Pagination is restricted to the same scheme and host as the start URL.
|
|
|
|
## Example payload
|
|
|
|
```json
|
|
{
|
|
"url": "https://example.com/articles",
|
|
"selectors": {
|
|
"headline": "h2.article-title",
|
|
"links": "a.article-link::attr(href)",
|
|
"next": "a[rel='next']::attr(href)"
|
|
},
|
|
"max_pages": 3,
|
|
"wait_seconds": 2,
|
|
"output_format": "json",
|
|
"headless": true,
|
|
"user_agent": "",
|
|
"respect_robots": true,
|
|
"rate_limit_seconds": 2,
|
|
"screenshot": false
|
|
}
|
|
```
|
|
|
|
## Smoke test payload
|
|
|
|
Use this payload to verify the scraper against the public demo site `https://quotes.toscrape.com/` while respecting robots.txt. It should return parseable JSON, quote items, a saved JSON file, an HTML capture path, and screenshot paths only when `screenshot` is `true`.
|
|
|
|
```json
|
|
{
|
|
"url": "https://quotes.toscrape.com/",
|
|
"selectors": {
|
|
"quotes": ".quote",
|
|
"text": ".text",
|
|
"author": ".author",
|
|
"tags": ".tag"
|
|
},
|
|
"max_pages": 1,
|
|
"wait_seconds": 1,
|
|
"output_format": "json",
|
|
"headless": true,
|
|
"user_agent": "",
|
|
"respect_robots": true,
|
|
"rate_limit_seconds": 1,
|
|
"screenshot": false
|
|
}
|
|
```
|
|
|
|
## Deployment notes
|
|
|
|
The agent declares a larger runtime budget because browser work can be CPU/memory intensive. Actual browser execution is performed through the workspace sandbox helper using the SeleniumBase image, so files written under `/workspace/outputs/seleniumbase-website-scraper/` are durable workspace outputs.
