Alpaca Market Data - News API

  title: Alpaca API (Trading, Market Data, Broker) Account Market Data - News API
  description: A grounded, curated OpenAPI description of Alpaca's public REST surface. Alpaca is a developer-first, commission-free brokerage whose stock, ETF, options, and crypto trading and market data are exposed entirely through APIs. This document covers the three REST products - the Trading API (api.alpaca.markets/v2, with a free paper sandbox at paper-api.alpaca.markets/v2), the Market Data API (data.alpaca.markets, with v2 stocks, v1beta3 crypto, and v1beta1 options/news/screener namespaces), and the Broker API (broker-api.alpaca.markets/v1). Real-time WebSocket streaming for market data is described in the companion AsyncAPI document at asyncapi/alpaca-markets-asyncapi.yml. Trading and Market Data authenticate with the APCA-API-KEY-ID and APCA-API-SECRET-KEY headers (or OAuth2 for third-party apps); the Broker API uses HTTP Basic auth. This spec is a representative subset of the full API for discovery purposes, not an exhaustive vendor specification.
