## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
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.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## 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.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## Reverb Gear Price Alert Bot

Monitor [Reverb.com](https://reverb.com) for new music gear listings matching your criteria. Get instant Discord or email alerts when guitars, amps, pedals, synths, and more match your price and condition preferences.

### What does it do?

This Actor watches Reverb.com for deals on music equipment. You define a **watchlist** of items you're looking for (e.g., "Fender Jazzmaster under $800"), and the bot:

1. Queries the Reverb API for each watchlist item
2. Compares results against previously seen listings (stored between runs)
3. Sends alerts for **new listings** and **price drops** via Discord webhook and/or email
4. Saves all alerts to the Apify dataset for review

Set it up on a **schedule** (e.g., every hour) and never miss a deal again.

### How to use

#### 1. Basic setup

Configure your watchlist with search queries and optional filters:

```json
{
    "watchlist": [
        {
            "query": "Fender Jazzmaster",
            "maxPrice": 800,
            "condition": "all"
        },
        {
            "query": "Boss DD-500",
            "maxPrice": 200,
            "condition": "excellent"
        },
        {
            "query": "Fender Twin Reverb",
            "maxPrice": 900,
            "category": "amps"
        }
    ]
}
```

#### 2. Discord alerts (recommended)

Get rich embeds in your Discord channel with listing details, photos, and direct links.

**Setting up a Discord webhook:**

1. Open your Discord server
2. Go to **Server Settings** > **Integrations** > **Webhooks**
3. Click **New Webhook**, name it (e.g., "Reverb Deals"), pick a channel
4. Copy the webhook URL
5. Paste it in the `discordWebhookUrl` input field

#### 3. Email alerts

Enter your email address in the `emailTo` field to receive a summary email with all new matches. Requires the Actor to run on the Apify platform with a valid token.

#### 4. Schedule it

For best results, schedule this Actor to run periodically:

- **Every hour**: Good for popular items with lots of new listings
- **Every 4 hours**: Balanced coverage for most gear
- **Daily**: Sufficient for niche or expensive items

In Apify Console: Actor page > **Schedules** tab > **Create schedule**

### Watchlist item options

Each item in the watchlist supports these fields:

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `query` | string | Yes | Search term (e.g., "Gibson Les Paul", "MXR Phase 90") |
| `maxPrice` | number | No | Maximum price in USD. Only alert for listings at or below this price. |
| `minPrice` | number | No | Minimum price in USD. Filter out listings below this price. |
| `condition` | string | No | Filter by condition: `all`, `mint`, `excellent`, `very_good`, `good`, `fair`, `poor` |
| `category` | string | No | Reverb category slug: `electric-guitars`, `acoustic-guitars`, `bass`, `drums`, `keyboards-synths`, `amps`, `effects-pedals`, etc. |

### Alert types

#### New Listing

Triggered when a listing appears that hasn't been seen in any previous run. The bot tracks seen listing IDs in a persistent Key-Value Store.

#### Price Drop

Triggered when a previously seen listing has a lower price than the last time it was checked. Shows both the current and previous price.

### Input reference

| Field | Type | Default | Description |
|-------|------|---------|-------------|
| `watchlist` | array | Required | List of watch items (see above) |
| `discordWebhookUrl` | string | - | Discord webhook URL for real-time alerts |
| `emailTo` | string | - | Email address for alert summaries |
| `alertOnPriceDrop` | boolean | `true` | Send alerts when existing listings drop in price |
| `maxAlerts` | integer | `20` | Max alerts per run (0 = unlimited) |
| `maxListingsPerQuery` | integer | `50` | Listings to check per query (1-100) |
| `stateRetentionDays` | integer | `30` | Days to remember seen listings before cleanup |
| `proxyConfiguration` | object | Apify Proxy | Proxy settings |

### Output

Each alert saved to the dataset contains:

```json
{
    "alertType": "new_listing",
    "matchedQuery": "Fender Jazzmaster",
    "listingId": "12345678",
    "title": "2019 Fender Player Jazzmaster - Sunburst",
    "price": 649.99,
    "previousPrice": null,
    "priceDrop": null,
    "condition": "Excellent",
    "shopName": "Guitar Center Pro",
    "url": "https://reverb.com/item/12345678",
    "photo": "https://images.reverb.com/...",
    "publishedAt": "2026-03-20T10:00:00Z",
    "alertSentAt": "2026-03-20T10:15:00Z"
}
```

### State persistence

The bot uses an Apify Key-Value Store (`reverb-alert-state`) to track which listings it has already seen. This persists between runs so you only get alerted once per new listing. Listings older than the `stateRetentionDays` setting (default: 30 days) are automatically cleaned up.

### Tips

- **Start broad, then refine**: Begin with just a query and no price filter to see what's available, then add thresholds.
- **Use categories**: Adding a `category` filter reduces false positives (e.g., "Fender" without a category might match strings, picks, etc.).
- **Multiple webhooks**: Run separate Actor instances with different Discord webhooks to route alerts to different channels.
- **Cost optimization**: This Actor uses the Reverb public API (no browser needed), so it runs fast and cheap. A typical run with 5 watchlist items uses minimal compute.

### Limitations

- The Reverb public API returns up to 100 listings per query. If you need deeper historical coverage, increase `maxListingsPerQuery`.
- Discord webhooks have a rate limit of ~30 messages per minute. The bot adds delays between messages to respect this.
- Email alerts require the Actor to run on the Apify platform with a valid `APIFY_TOKEN`.

# Actor input Schema

## `watchlist` (type: `array`):

List of items to watch for. Each item defines a search query with optional price and condition filters.

## `discordWebhookUrl` (type: `string`):

Discord webhook URL for sending alerts. Create one in Discord: Server Settings > Integrations > Webhooks.

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {

        }
    }
}
```

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).
