## GraphOps services on Ethereum Sepolia

One API key from your organization can include every service you use, and all of them draw from the organization's credit balance.

### RPC

Send JSON-RPC requests over HTTPS, or open a WebSocket for subscriptions. Archive data is available: historical state, such as eth_call at a past block, and historical event logs. Ethereum Sepolia RPC is not published with tracing.

### Subgraphs

Query any Subgraph that The Graph Network serves on Ethereum Sepolia by Deployment CID or Graph Network Subgraph ID. Managed indexing runs on Ethereum Sepolia: publish a Managed Subgraph and GraphOps indexes it. Managed Subgraphs need a monthly plan.

## Make a first Ethereum Sepolia request

This request reads the latest Ethereum Sepolia block number with eth_blockNumber. Create an API key that includes RPC in your organization and export it as GRAPHOPS_API_KEY. The example sends it in the Authorization header.

## Ethereum Sepolia questions

What is the Ethereum Sepolia chain ID?

Ethereum Sepolia is a testnet with EVM chain ID 11155111. Its CAIP-2 network ID is eip155:11155111.

What is the GraphOps Ethereum Sepolia RPC endpoint?

Send HTTPS JSON-RPC requests to https://rpc.graphops.xyz/v1/evm/11155111, and open WebSocket connections to wss://rpc.graphops.xyz/v1/evm/11155111. Authenticate with an API key from your organization that includes RPC, in the Authorization header or as a route token at the end of the path.

Does GraphOps Ethereum Sepolia RPC serve archive data?

Yes. Historical state, such as eth_call at a past block, and historical event logs are available on Ethereum Sepolia.

Does GraphOps Ethereum Sepolia RPC support tracing?

No. Ethereum Sepolia RPC is not published with tracing.

Which network name do Ethereum Sepolia Subgraphs use?

Subgraphs that index Ethereum Sepolia declare network: sepolia in their manifest.

Can GraphOps index my own Subgraph on Ethereum Sepolia?

Yes. Managed indexing runs on Ethereum Sepolia, so you can deploy a Managed Subgraph that GraphOps indexes. Managed Subgraphs need a monthly plan.
