## 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.

# README

## eBay Aftermarket Parts — Price, Brand Tier & Fitment

**Search eBay aftermarket auto parts by part and vehicle, and get price, condition, brand, seller — plus two things nobody else surfaces:** a hand-authored **brand-quality tier** (OE/Premium / Mid / Budget) and real **fitment** via eBay's own compatibility check. Bring your own free eBay developer key.

For parts resellers, repricing tools, garages and auto lead-gen.

### What you get

Per listing:

- **Listing** — `itemId`, `title`, `price`, `currency`, `condition`, `conditionId`, `buyingOptions[]`, `itemUrl`, `image`, `itemLocation`
- **Seller** — `seller`, `sellerFeedbackPct`, `sellerFeedbackScore`
- **Brand + tier** — `brand` from eBay's aspect, and `brandTier` = **OE/Premium**, **Mid** or **Budget** from a curated brand map (the differentiator)
- **Fitment** (when a vehicle is passed) — `compatibility` = `COMPATIBLE` / `NOT_COMPATIBLE` / `UNDETERMINED`, plus `compatibilityNote`

### Output sample

```json
{
  "itemId": "v1|1234567890|0",
  "title": "Bosch QuietCast Front Brake Pads BC1234",
  "price": 48.97,
  "currency": "USD",
  "condition": "New",
  "conditionId": "1000",
  "brand": "Bosch",
  "brandTier": "OE/Premium",
  "seller": "partsdirect_us",
  "sellerFeedbackPct": 99.4,
  "sellerFeedbackScore": 128456,
  "buyingOptions": ["FIXED_PRICE"],
  "itemUrl": "https://www.ebay.com/itm/1234567890",
  "image": "https://i.ebayimg.com/.../s-l1600.jpg",
  "itemLocation": "US",
  "compatibility": "COMPATIBLE",
  "compatibilityNote": null
}
```

`compatibility` is `null` when no vehicle is provided.

### Input

| Field | Type | Default | Description |
|-------|------|---------|-------------|
| `query` | string | `brake pads` | Part to search, e.g. `oil filter` |
| `make` / `model` / `year` | string | — | Vehicle for the fitment check |
| `trim` / `engine` | string | — | Optional, for a more precise fitment check |
| `clientId` | string (secret) | — | eBay App ID / Client ID (Production) |
| `clientSecret` | string (secret) | — | eBay Cert ID / Client Secret (Production) |
| `marketplaceId` | string | `EBAY_US` | `EBAY_US`, `EBAY_GB`, `EBAY_DE`, … |
| `categoryId` | string | `6030` | eBay category (6030 = Motors Parts & Accessories) |
| `filter` | string | — | Raw Browse filter, e.g. `conditions:{NEW},price:[10..80]` |
| `sort` | string | — | e.g. `price` (lowest first), `-price` |
| `maxResults` | integer | `50` | Cap on listings returned |

### Example input

```json
{
  "query": "brake pads",
  "make": "Honda",
  "model": "Accord",
  "year": "2020",
  "clientId": "YOUR_APP_ID",
  "clientSecret": "YOUR_CERT_ID"
}
```

### Bring your own key (free, required)

Create a free application at **developer.ebay.com**, get your **Production** keys, and pass `clientId` (App ID) and `clientSecret` (Cert ID) — both stored as secret inputs. The actor authenticates via OAuth client-credentials. **Without both keys the actor exits cleanly with no results** (it uses your own eBay rate limits, keeping cost low).

### Why this actor

- **`brandTier` — a quality signal nobody else has** — eBay exposes the brand but not whether it's OE/Premium, Mid or Budget; this actor attaches it from a hand-curated map.
- **Real fitment** — eBay's own `check_compatibility` per listing, not a guess.
- **BYO-key** — you get your own eBay quota; you only pay Apify for the rows returned.

### Pricing

Pay per result — **$3.00 per 1,000 results** (one result = one listing row). BYO eBay key means you use your own eBay rate limits; you only pay Apify for the results returned.

### Important: fitment is a signal, not a guarantee

A `COMPATIBLE` verdict comes from eBay's compatibility check, which relies on seller-supplied fitment data — it can be missing or wrong. `UNDETERMINED` means the listing has no fitment catalog. **Always verify the exact part number against your vehicle before buying.** The `brandTier` is a convenience heuristic, not an endorsement. Prices change constantly; not affiliated with eBay.

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).
