  version: v1
  description: 'The Robinhood Crypto Trading API lets developers programmatically access their own Robinhood Crypto account: view buying power and holdings, pull market data (best bid/ask and estimated fill prices), enumerate supported trading pairs, and place, retrieve, and cancel cryptocurrency orders (market, limit, stop-loss, and stop-limit). Requests are authenticated per-request with an API key plus an Ed25519 request signature over the API key, UNIX timestamp, request path, method, and body, supplied in the x-api-key, x-timestamp, and x-signature headers.'
