Official SDKs

The official SDKs cover the same REST endpoints and the same WebSocket stream documented on this site. Each one is a thin wrapper with no runtime dependencies, and every method returns the same JSON shape the API sends.

Python

Package name on PyPI is dino-markets. Requires Python 3.9 or later.

pip install dino-markets

from dino_markets import Dino

client = Dino()  # reads DINO_API_KEY, or pass api_key= directly

markets = client.markets(sport="baseball")
arbs = client.find_arbitrage(sport="baseball", limit=20)
history = client.history(markets["markets"][0]["id"])

Streaming needs the stream extra, which pulls in centrifuge-python, and a Basic or Pro key. A Free key's stream_token() call raises PlanError (402) before any socket opens.

pip install "dino-markets[stream]"

TypeScript

Package name on npm is dino-markets. Built on the native fetch API, so it runs in Node 18+, Deno, Bun, and the browser with no bundler polyfill.

npm install dino-markets

import { Dino } from "dino-markets";

const dino = new Dino(); // reads DINO_API_KEY, or pass { apiKey: "..." }

const { markets } = await dino.markets({ sport: "baseball" });
const arbs = await dino.findArbitrage({ sport: "baseball", limit: 20 });
const history = await dino.history(markets[0].id);

Streaming needs the optional centrifuge peer dependency and a Basic or Pro key. A Free key's streamToken() call throws PlanError (402) instead of opening a socket.

npm install centrifuge

Errors

Both SDKs raise a typed error for every non-2xx response: AuthenticationError on 401, PlanError on 402, RateLimitError on 429 with the retry delay attached, and ServerError on 5xx, all subclasses of a shared DinoError.
