Brave NewCoin API

Cryptocurrency / API Key Intermediate HTTPS
Varies by plan (check documentation)

Overview

Brave NewCoin aggregates real-time and historical price data from over 200 cryptocurrency exchanges to compute market index prices for thousands of assets. The API provides OHLCV time series, market capitalization rankings, and composite price indices used by institutional finance platforms. It requires authentication via Auth0 before accessing any endpoint.

💡

Beginner Tip

You must first obtain a bearer token by POSTing your API credentials to the Auth0 authentication endpoint — refer to the quickstart guide at bravenewcoin.com/developers. Once you have the token, pass it as Authorization: Bearer TOKEN in every subsequent request.

Common Errors & Troubleshooting

401 Unauthorized on all endpoints Brave NewCoin uses OAuth2 client credentials flow, so a simple API key in a header will not work.
POST your client_id and client_secret to the Auth0 token endpoint and use the returned access_token as your Bearer token.
Token expiry mid-session Access tokens expire after a set duration (typically 24 hours).
Implement token refresh logic that re-authenticates and updates the stored token before expiry.
Asset ID not found Brave NewCoin uses internal UUIDs for assets, not ticker symbols like BTC.
Call the /asset endpoint first to look up the correct UUID for the asset you want, then use that ID in subsequent calls.
