## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

## Knowde Scraper — Chemical Ingredients, Suppliers & TDS/SDS

> **Chemicals & ingredients marketplace data** — Knowde product search, supplier storefronts, certifications, and TDS/SDS metadata.

Not affiliated with, sponsored by, or endorsed by Knowde. Provided for informational and research purposes only. You are responsible for complying with applicable laws and Knowde terms of use.

Scrape the **Knowde Marketplace** chemical ingredients and polymers catalog by **keyword search**, **product URL**, or **supplier storefront**. Export **ingredient attributes**, **certifications**, **applications**, **TDS/SDS document metadata**, and **supplier contacts** as clean JSON — a **Knowde scraper** / **Knowde API alternative** for **sourcing**, **competitive intelligence**, and **MCP** / Python / Node.js pipelines.

***

### Key Features

- **Keyword product search** — paginated Knowde search results (36 products per page)
- **Product detail enrichment** — Enhanced TDS sections, documents, similar products (optional)
- **Supplier storefronts** — company description, email, phone, HQ, brands, featured products
- **Storefront catalogs** — crawl supplier `/products` listings at scale
- **Quick filters** — With SDS, With TDS, Fast response times
- **Structured attributes** — ingredient name, physical form, labeling claims, certifications, applications
- **Fast HTTP scraping** — `curl_cffi` Chrome TLS impersonation; no headless browser
- **Residential proxy ready** — sticky Apify sessions help pass AWS WAF on product detail pages

***

### Use Cases

| Use case | What you get | Why it helps |
| :--- | :--- | :--- |
| **Ingredient sourcing** | Products matching a chemistry keyword + supplier slugs | Build shortlists for R\&D / procurement |
| **Supplier intelligence** | Storefront contacts, brands, featured SKUs | Map who sells what on Knowde |
| **Compliance screening** | Labeling claims + certifications blocks | Filter Non-GMO / Kosher / GRAS candidates |
| **Document discovery** | TDS / SDS / declaration metadata | Find which SKUs publish safety & tech sheets |
| **Competitive monitoring** | Repeat searches / storefront catalogs | Track new listings in a category |

***

### When to use this Actor

- Knowde **product search** by ingredient, polymer, or chemistry keyword
- **Supplier storefront** extraction (contacts + featured products)
- **Product URL** enrichment when you already have Knowde PDP links
- **Sourcing research** — attributes, applications, certifications, document presence

### When not to use this Actor

- **Official Knowde Developer API** workflows that require a Knowde company API client (OAuth)
- **Live quote / sample / RFQ submission** automation
- **List prices or inventory** — Knowde is discovery/RFQ oriented; public pages do not expose transactional pricing
- **Other chemical portals** — this Actor covers Knowde only

### MCP and AI assistants

Use this Actor from AI tools via [Apify MCP](https://docs.apify.com/platform/integrations/mcp).
Connect your Apify account, then call this Actor by its Store ID / name (`crawloop/knowde-scraper`).

Example prompts:

- "Run Knowde Scraper for glycerin and return the top 20 product rows as JSON"
- "Scrape a Knowde supplier storefront and summarize email, phone, and featured products"
- "Search Knowde for fumed silica with SDS filter and list supplier slugs"

***

### FAQ

**Does this return prices?**\
No. Public Knowde pages are oriented around discovery and RFQ (quote / sample requests), not list prices.

**Do I need a Knowde login?**\
No for public search, storefront, and product pages. Some document downloads may still require a Knowde account in the browser — this Actor returns document metadata when present in the page payload.

**Why use residential proxy?**\
Product detail URLs can trigger AWS WAF challenges on datacenter IPs. Search and many storefront pages often work without proxy; enable Apify RESIDENTIAL for reliable PDP enrichment.

**Is this the official Knowde API?**\
No. Knowde offers a separate Developer API for platform customers. This Actor extracts publicly rendered Marketplace data for automation on Apify.

**Can I scrape with Python or Node.js?**\
Yes — use the Apify client examples above, or call the Actor from MCP / AI assistants.

# Actor input Schema

## `searchQueries` (type: `array`):

Knowde Marketplace keyword searches (e.g. glycerin, fumed silica, silicone). Each query is paginated and returns product listing rows.

## `startUrls` (type: `array`):

Knowde URLs to scrape directly: product pages (/stores/{supplier}/products/{slug}), supplier storefronts (/stores/{supplier}), storefront product catalogs (/stores/{supplier}/products), or search pages (/search?q=...).

## `maxItems` (type: `integer`):

Stop after this many dataset items (products, listings, suppliers).

## `maxPages` (type: `integer`):

Maximum pages per search query or storefront product catalog (36 products per page).

## `enrichProducts` (type: `boolean`):

When scraping search or storefront catalogs, also fetch full product detail pages (Enhanced TDS sections, documents, similar products). Recommended with residential proxy — product pages may hit AWS WAF without it.

## `includeDocuments` (type: `boolean`):

Include TDS / SDS / declaration document metadata on enriched product pages.

## `includeSimilarProducts` (type: `boolean`):

Include similar / related product references from product detail pages.

## `withSds` (type: `boolean`):

When searching, prefer products that have a Safety Data Sheet (with-sds).

## `withTds` (type: `boolean`):

When searching, prefer products that have a Technical Data Sheet (with-tds).

## `withFastResponse` (type: `boolean`):

When searching, prefer suppliers marked with fast response times.

## `requestDelaySecs` (type: `number`):

Pause between HTTP requests on the same session.

## `proxyConfiguration` (type: `object`):

Apify Proxy settings. Residential sticky sessions improve success on product detail pages (AWS WAF).

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
