## 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

## CoinGecko Tokens by Category Scraper

Pulls every token listed in a CoinGecko category (DeFi, meme, AI, L1, ecosystem tags, etc.) with current price, market cap, 24h volume, rank, and price change. Uses the free public CoinGecko API — **no API key required**.

### Example output row

```json
{
  "category": "meme-token",
  "coin_id": "dogecoin",
  "symbol": "doge",
  "name": "Dogecoin",
  "price_usd": 0.1423,
  "market_cap_usd": 20895432198,
  "rank": 8,
  "volume_24h_usd": 1034598217,
  "change_pct_24h": 3.14,
  "circulating_supply": 146852429611.0,
  "all_time_high_usd": 0.7376,
  "logo_url": "https://coin-images.coingecko.com/coins/images/5/large/dogecoin.png",
  "last_updated": "2026-06-21T18:00:00.000Z",
  "snapshot_at": "2026-06-21T18:47:01+00:00"
}
```

### How to use

Pass a JSON input with a `category` array of CoinGecko category slugs.\
Category slugs come from the `category_id` field of the [/coins/categories/list](https://api.coingecko.com/api/v3/coins/categories/list) endpoint — they are **not** human-readable names.

```json
{
  "category": [
    "layer-1",
    "meme-token",
    "decentralized-finance-defi",
    "artificial-intelligence",
    "gaming",
    "ethereum-ecosystem",
    "solana-ecosystem"
  ]
}
```

| Field | Type | Default | Description |
|---|---|---|---|
| `category` | `string[]` | `["layer-1","meme-token","artificial-intelligence"]` | One or more CoinGecko category slugs. Invalid slugs are skipped gracefully. |

Each category returns up to **100 tokens** ordered by market cap descending.\
Large categories (e.g. `ethereum-ecosystem` has 4000+ tokens) are intentionally truncated to the top 100 — buyers want the leaders, not the long tail.

#### Known slug quirks

- `polygon-ecosystem-` has a trailing dash (CoinGecko's bug, not ours).
- CoinGecko deprecated some legacy slugs in 2025 — if a slug returns 0 results, verify it against `/coins/categories/list`.

### Pricing

| Event | Cost |
|---|---|
| `dataset-item` — per token row returned | **$0.001** |

A run over 3 categories averaging 80 tokens each costs $0.24.

### Buyer

- **Portfolio trackers** monitoring which tokens dominate a sector (AI coins, RWA, L2s) without a CoinGecko Pro subscription.
- **Quant researchers** seeding a watchlist from an entire category in one API call.
- **Trading bots** that need a refreshed universe of tokens per sector on a schedule.
- **DeFi dashboards** displaying sector-level market cap and volume aggregates.
- **Crypto journalists** snapshotting category leaders at publication time.

### Source

CoinGecko free public REST API — no authentication required.

```
GET https://api.coingecko.com/api/v3/coins/markets
    ?vs_currency=usd
    &category={category_slug}
    &order=market_cap_desc
    &per_page=100
    &page=1
    &sparkline=false
    &price_change_percentage=24h
```

Rate limit: ~10–30 requests/minute on the unauthenticated tier.\
The actor automatically backs off 60 seconds on a 429 response and retries once.
