Yellowstone
Authentication
Your FluxRPC API key must be included in every gRPC request for authentication.
Required Header
Pass your API key in the x-token header:
x-token: <your-API-key>Plan Requirements
Yellowstone gRPC access requires a Developer plan or higher. Free and Starter plans do not have access to gRPC services.
Bandwidth Requirements
Your Internet connection must be fast enough to receive the data you subscribe to on Yellowstone. If your connection is too slow, our server will disconnect you with an appropriate error. We buffer some updates on our end to account for temporary issues and will never drop updates.
If you encounter connection speed issues, move your server closer to FluxRPC or subscribe to less data.
API Key Types
Only standard API keys work with gRPC. Shielded API keys are not supported. You must have bandwidth remaining in your account for the service to function.
