# Web Scraping API — `POST /scrape/web`
|
||||
|
||||
One endpoint to fetch any URL, optionally with JS rendering, proxies, AI extraction, and screenshots. Synchronous.
|
||||
|
||||
> Reach for this only when the user gave you a specific URL, or when no Scraper API covers the field. Otherwise the platform-specific APIs return pre-extracted JSON without direct page access. Use only for public pages or content the user is authorized to access.
|
||||
|
||||
## Minimal request
|
||||
|
||||
```python
|
||||
import requests
|
||||
|
||||
# Multiple outputs (or include "json") → response is a JSON object
|
||||
resp = requests.post(
|
||||
"https://api.hasdata.com/scrape/web",
|
||||
headers={"x-api-key": API_KEY},
|
||||
json={"url": "https://example.com", "outputFormat": ["markdown", "json"]},
|
||||
timeout=300,
|
||||
)
|
||||
data = resp.json()
|
||||
assert data["requestMetadata"]["status"] == "ok"
|
||||
print(data["markdown"])
|
||||
|
||||
# Single non-JSON output → response IS the raw content (markdown/html/text bytes)
|
||||
resp = requests.post(
|
||||
"https://api.hasdata.com/scrape/web",
|
||||
headers={"x-api-key": API_KEY},
|
||||
json={"url": "https://example.com", "outputFormat": ["markdown"]},
|
||||
timeout=300,
|
||||
)
|
||||
print(resp.text) # raw markdown — no JSON parsing
|
||||
```
|
||||
|
||||
## Body parameters
|
||||
|
||||
| Parameter | Type | Notes |
|
||||
|---|---|---|
|
||||
| `url` | string | **Required.** Absolute URL. |
|
||||
| `outputFormat` | string[] | `html`, `text`, `markdown`, `json`. **Single non-JSON format → raw content as the body** (not JSON-wrapped); multiple formats → JSON object with one key per format. Always include `"json"` (or another format) when you also need `requestMetadata`. |
|
||||
| `proxyType` | enum | `datacenter` (default) or `residential` — use residential only for authorized geo/availability testing where terms and access controls permit it. |
|
||||
| `proxyCountry` | string | ISO 3166-1 alpha-2 — `US`, `UK`, `DE`, `FR`, `IT`, `SE`, `BR`, `CA`, `JP`, `SG`, `IN`, `ID`, `IE`. |
|
||||
| `jsRendering` | bool | Headless browser — required for SPAs and dynamically-injected content. |
|
||||
| `wait` / `waitFor` | int (ms) / CSS string | Fixed delay vs. wait-until-selector. Prefer `waitFor`. |
|
||||
| `jsScenario` | array | Sequence of click/fill/wait/scroll/evaluate. Requires `jsRendering`. |
|
||||
| `headers` | object | Custom headers. **Cookies go here too — no separate `cookies` parameter.** |
|
||||
| `screenshot` | bool | Returns a CDN URL in the response. |
|
||||
| `extractRules` | object | CSS selectors → field text. `@attr` for attributes. **First match only**, missing → `null`. |
|
||||
| `aiExtractRules` | object | Typed LLM extraction. Types: `string`, `number`, `boolean`, `list`, `item`. |
|
||||
| `extractEmails` / `extractLinks` | bool | Quick helpers. |
|
||||
| `blockResources` / `blockAds` | bool | Skip images/CSS/ads — speeds text-only scrapes. |
|
||||
| `blockUrls` | string[] | Glob patterns to block subresources. |
|
||||
| `removeBase64Images` | bool | Strip inline base64 from response. |
|
||||
| `includeOnlyTags` / `excludeTags` | string[] | Trim DOM before serialization. |
|
||||
|
||||
## CSS extraction (`extractRules`)
|
||||
|
||||
```python
|
||||
"extractRules": {
|
||||
"title": "h1",
|
||||
"links": "a @href", # @attr extracts attribute
|
||||
"price": ".price-now",
|
||||
}
|
||||
```
|
||||
|
||||
First match per selector. For lists of records, use `aiExtractRules` with `type: "list"`.
|
||||
|
||||
## AI extraction (`aiExtractRules`)
|
||||
|
||||
```python
|
||||
"aiExtractRules": {
|
||||
"title": {"type": "string"},
|
||||
"price": {"type": "number"},
|
||||
"in_stock": {"type": "boolean"},
|
||||
"tags": {"type": "list", "description": "category tags"},
|
||||
"author": {"type": "item", "output": {
|
||||
"name": {"type": "string"},
|
||||
"verified": {"type": "boolean"},
|
||||
}},
|
||||
"reviews": {"type": "list", "output": {
|
||||
"rating": {"type": "number"},
|
||||
"text": {"type": "string"},
|
||||
}},
|
||||
}
|
||||
```
|
||||
|
||||
Use when layout varies across pages; otherwise prefer `extractRules` for determinism and predictability.
|
||||
|
||||
## JS scenarios
|
||||
|
||||
```python
|
||||
"jsScenario": [
|
||||
{"fill": ["#email", "user@example.com"]},
|
||||
{"fill": ["#password", PASSWORD]},
|
||||
{"click": "#login"},
|
||||
{"waitFor": ".dashboard"},
|
||||
{"scrollY": 2000},
|
||||
{"waitForAndClick": ".load-more"},
|
||||
{"evaluate": "window.__APP_STATE__"},
|
||||
]
|
||||
```
|
||||
|
||||
Actions: `click`, `fill: [sel, val]`, `wait: ms`, `waitFor: sel`, `waitForAndClick: sel`, `scrollX/scrollY: px`, `evaluate: "JS"`. Sequential. Missing element on `click`/`fill` fails the request — wrap with `waitFor` first.
|
||||
|
||||
## Auth via cookies
|
||||
|
||||
```python
|
||||
"headers": {
|
||||
"User-Agent": "Mozilla/5.0 ...",
|
||||
"Cookie": "session=abc; csrf=xyz",
|
||||
"Accept-Language": "en-US,en;q=0.9",
|
||||
}
|
||||
```
|
||||
|
||||
Capture cookies once in a real browser (devtools → Storage → Cookies), forward via the `Cookie` header. Only with explicit user permission and authority to access that account/content; never use cookies to bypass someone else's access controls.
|
||||
|
||||
## Slim response & speed
|
||||
|
||||
```python
|
||||
{
|
||||
"blockResources": True, # skip images/CSS/fonts
|
||||
"blockAds": True, # skip ad/tracking
|
||||
"blockUrls": ["**.googletagmanager.com/**", "**.doubleclick.net/**"],
|
||||
"removeBase64Images": True,
|
||||
"excludeTags": ["script", "style", "nav", "footer"],
|
||||
}
|
||||
```
|
||||
|
||||
Reduces response size 60–90% on noisy pages.
|
||||
|
||||
## Response shape
|
||||
|
||||
The wrapper is JSON **only when** the response is JSON-wrapped — i.e. multiple `outputFormat` values, or a single value that includes `"json"`. With a single non-JSON format the response body is the raw content (`text/markdown`, `text/html`, `text/plain`).
|
||||
|
||||
```json
|
||||
{
|
||||
"requestMetadata": { "id": "uuid", "status": "ok", "url": "..." },
|
||||
"headers": { "content-type": "text/html" },
|
||||
"screenshot": "https://...jpeg",
|
||||
"content": "<!DOCTYPE html>...", // outputFormat: html
|
||||
"markdown": "# Title\n...", // outputFormat: markdown
|
||||
"text": "Title\n...",
|
||||
"extractRules": { ... }, // present iff sent
|
||||
"aiExtractRules": { ... }, // present iff sent
|
||||
"extractedEmails": [ ... ], // iff extractEmails: true
|
||||
"extractedLinks": [ ... ] // iff extractLinks: true
|
||||
}
|
||||
```
|
||||
|
||||
## Batch (`POST /scrape/batch/web`)
|
||||
|
||||
Async wrapper for >1k URLs running the same extraction. Returns `jobId`; poll status, page `/results`. Per-batch cap **10,000 URLs**. For small workloads loop the sync endpoint at concurrency = plan limit.
|
||||
|
||||
## Gotchas
|
||||
|
||||
- **Disable `jsRendering` first**, enable only when the page needs it — most static pages parse fine without a headless browser.
|
||||
- **`waitFor` > `wait`.** Selector-based waits adapt to network speed.
|
||||
- **Cookies via `headers["Cookie"]` only.**
|
||||
- **`extractRules` returns first match** — for arrays use `aiExtractRules` `type: "list"`.
|
||||
- **Set client timeout ≥ 300 s** to match the server deadline.
|
||||
- **`requestMetadata.status === "ok"` is the only success signal.**
