Celestia gRPC API Overview

Updated on
Jul 04, 2025

Overview​

The Celestia gRPC API offers fast, low-latency access to network data. Use it to query blockchain state, monitor on-chain activity, estimate gas, check transaction status, and detect network upgrades.

Access​

You can access Celestia gRPC directly through your existing QuickNode Celestia endpoint—no additional add-ons are needed. The gRPC services are available on port 9090, a dedicated and secure channel for gRPC communication.

Endpoint and Token Configuration​

When connecting to Celestia gRPC services, the port must be specified in the URL:

  • Endpoint: The name of your endpoint followed by .celestia-mainnet.quiknode.pro and the port number 9090 (e.g., https://docs-demo.celestia-mainnet.quiknode.pro:9090)
  • Token: The alphanumeric string that follows the endpoint name in the URL

For example, if your endpoint looks like this: https://docs-demo.celestia-mainnet.quiknode.pro/123456789/, then your authentication credentials would be:

  • Endpoint: https://docs-demo.celestia-mainnet.quiknode.pro:9090
  • Token: 123456789
