## 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

## Altcoin BTC-Relative Performance

> Ranks 488 altcoin/BTC pairs by 24h performance relative to Bitcoin using Binance public data: top gainers, losers, volume leaders, and altseason breadth signal. No API key required.

***

### ⚡ Run in 30 seconds

Click **Start** with default settings — you get the top 20 altcoin gainers and losers vs BTC, the highest-volume altcoin/BTC pairs, and a market breadth signal indicating whether altseason conditions are present. No API key needed.

***

### What It Does

Fetches all Binance XXXBTC trading pairs and ranks altcoins by their performance vs Bitcoin:

- **Top gainers vs BTC**: Alts outperforming Bitcoin the most
- **Top losers vs BTC**: Alts underperforming Bitcoin the most
- **Volume leaders**: Highest-volume pairs regardless of direction
- **Market breadth**: % of alts beating BTC with altseason classification:
  - `strong_altseason` (≥70% beating BTC)
  - `altseason` (55-70%)
  - `mixed` (45-55%)
  - `btc_dominance` (30-45%)
  - `strong_btc_dominance` (<30%)

***

### Input

| Field | Type | Default | Description |
|-------|------|---------|-------------|
| `topN` | integer | `30` | Results per category (gainers/losers/volume) |
| `minVolumeBtc` | number | `1.0` | Minimum 24h volume filter in BTC |
| `includeStables` | boolean | `false` | Include stablecoins vs BTC |

***

### Output

First item: `market_summary` with BTC price, 24h change, breadth % and signal.

Remaining items tagged with `rank_type`:

- `top_gainer` — change\_vs\_btc\_pct from highest to lowest
- `top_loser` — change\_vs\_btc\_pct from lowest to highest
- `volume_leader` — sorted by 24h volume USD

***

### Pricing

**$0.005 flat per run.** Binance public API, no authentication required.
