Getting Started

This guide covers everything you need to make your first connection to the Arcfeed Stream API.

Prerequisites

  • A valid API token — obtain one from the arcfeed.finance dashboard.
  • A gRPC or Connect RPC client. The Stream API uses Connect RPC over HTTP/2 with Protobuf encoding. Any Connect RPC or standard gRPC client works.

Authentication overview

All requests to the Stream API require a JWT token. Pass your token as the raw value of the Authorization header — no scheme prefix:

Authorization: <your-token>

Tokens are issued per account and can be managed from the arcfeed.finance dashboard. Each token is scoped to your account's subscription.

Next step

Follow the Quickstart to install the client library and stream your first trades in under five minutes.
