# 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": "...", // 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.**
