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). # README ## 🪙 Comparador de Preços de Criptomoedas entre Corretoras **Pare de pagar mais caro nas suas criptos.** Cada corretora cobra um preço diferente pela mesma moeda - este actor mostra o preço em **todas as principais corretoras de uma vez** e aponta a **mais barata**, pra você comprar sempre no melhor preço (e enxergar oportunidades de arbitragem). ![Comparação de preços de cripto entre corretoras](https://api.apify.com/v2/key-value-stores/8Fjh922xHv39c4blz/records/crypto-table-pt.png) Compara **Binance, OKX, Bybit, KuCoin, Bitget, Crypto.com, NovaDAX, Mercado Bitcoin** e mais. Para cada moeda: o preço em **cada corretora**, a **mais barata** e a **mais cara**, o spread e a melhor oportunidade de **arbitragem**, além de dados de mercado. **Uma linha por moeda** - exporte para CSV/Excel ou use a API em tempo real. > ⚡ Dados do motor por trás do [criptocortex.com](https://criptocortex.com). --- ### O que você recebe (por moeda) | Grupo | Campos | |---|---| | **Identificação** | `coinId`, `symbol`, `name`, `snapshotAt` | | **Preço** | `priceUsd`, `priceBrl`, `avgPriceBrl`, `minPriceBrl`, `maxPriceBrl`, `usdBrlRate` | | **Spread / arbitragem** | `priceDispersion`, `bestArbOpportunityPct`, `cheapestExchange`, `mostExpensiveExchange` | | **Por corretora (BRL)** | `binanceBrl`, `okxBrl`, `bybitBrl`, `bitgetBrl`, `kucoinBrl`, `cryptoComBrl`, `novadaxBrl`, `mercadoBitcoinBrl`, `coinextBrl`, `gateIoBrl` | | **Mercado** | `priceChange24h`, `high24h`, `low24h`, `ath`, `atl`, `marketCap`, `marketCapRank`, `signal`, `liquidityScore` | Um campo vem `null` quando aquela corretora não tem cotação da moeda no último snapshot. --- ### Moedas monitoradas Bitcoin (BTC), Ethereum (ETH), Solana (SOL), XRP, Cardano (ADA), Dogecoin (DOGE), Avalanche (AVAX), BNB, Tether (USDT), USD Coin (USDC). --- ### Como usar Deixe vazio para todas as moedas, ou filtre: ```json { "coins": ["bitcoin", "ethereum"] } ```` - `coins`: selecione uma ou mais moedas (vazio = todas) Exporte o dataset como **JSON / CSV / Excel**, ou chame a **API Standby** em tempo real (`POST /prices`). *** ### Exemplo de saída (uma moeda) ```json { "coinId": "bitcoin", "symbol": "BTC", "name": "Bitcoin", "snapshotAt": "2026-06-10T14:20:06.887284+00:00", "priceUsd": 61915.64, "priceBrl": 320277.2, "avgPriceBrl": 320277.2, "minPriceBrl": 320092.35, "maxPriceBrl": 320362.37, "bestArbOpportunityPct": 0.0844, "priceChange24h": 0.18, "signal": "neutral", "liquidityScore": 85, "binanceBrl": 320317.93, "okxBrl": 320277.02, "bybitBrl": 320302.36, "novadaxBrl": 320204.5, "mercadoBitcoinBrl": 320349, "cheapestExchange": "novadax", "mostExpensiveExchange": "kucoin" } ``` *** ### Perguntas frequentes **Os dados são atuais?** Retorna o último snapshot coletado das corretoras (atualizado a cada poucos minutos). **Qual a moeda?** Os preços por corretora são em **BRL**; `priceUsd` e `usdBrlRate` também vêm no retorno. **Por que alguma corretora vem null?** Nem toda corretora lista toda moeda; quando não há cotação no último snapshot, a coluna fica `null`. **Posso chamar em tempo real?** Sim. O endpoint Standby `POST /prices` responde de forma síncrona. *** #### 🔌 Integração via API **Execução em lote:** ```bash curl -X POST "https://api.apify.com/v2/acts/brasildados~comparador-precos-cripto/run-sync-get-dataset-items?token=SEU_TOKEN" \ -H "Content-Type: application/json" \ -d '{"coins":["bitcoin","ethereum"]}' ``` **Standby (`POST /prices`):** ```bash curl -X POST "https://brasildados--comparador-precos-cripto.apify.actor/prices" \ -H "Authorization: Bearer SEU_APIFY_TOKEN" \ -H "Content-Type: application/json" \ --compressed \ -d '{"coins":["bitcoin","ethereum"]}' ``` O token vai no header `Authorization: Bearer`, nunca na URL. *** ### Legal Preços têm caráter informativo e não são recomendação de investimento.
