## Pricing
from $0.00001 / result
This Actor is paid per event and usage. You are charged both the fixed price for specific events and for Apify platform usage.

## What's an Apify Actor?
Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
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.
In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):
```bash
npm install apify-client
```
In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):
```bash
pip install apify-client
```
In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):
````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash
In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).
If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).
For usage examples, see the [API](#api) section below.
For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).

JLCPCB Parts Finder
Find in-stock electronic components by specification — instantly.
---
### What It Does
Search **JLCPCB's entire in-stock catalog** of electronic components by electrical specifications. Instead of browsing pages of parts, describe what you need and get back matching components with stock counts, unit prices, and full specs.
**Supported component types:**
| Type | Search Filters |
|------|----------------|
| 🔲 **Resistors** | Resistance, package, tolerance, power |
| 🔵 **Capacitors** | Capacitance, package, voltage, tolerance |
| 🟡 **Inductors** | Inductance, package, current, tolerance |
| 🔴 **LEDs** | Color, package, voltage, current |
| ⚡ **MOSFETs** | Package, voltage, current, channel type |
| 🧠 **ICs** | Package, manufacturer, category |
---
### Use Cases
- **BOM generation** — automate finding the right parts for your circuit design
- **Design validation** — verify that components exist in JLCPCB stock before finalizing
- **Price comparison** — find the cheapest in-stock part matching your specs
- **Alt-part discovery** — find substitute components when your primary choice is out of stock
---
