Closed beta guide

Redeem your invite code

Go to /account and paste your invite code (RPCBOX-XXXX-XXXX-XXXX) into "Redeem an invite code". Your API key is shown exactly once — store it somewhere safe. Redemption activates the Growth tier and credits your account; no card is required during beta. The same page is your usage dashboard afterwards: per-method request counts, latencies, egress, credit balance. The key travels only in the Authorization header and is never persisted by the page.

First request

curl -s https://8-232-23-170.sslip.io/v1/evm/1 \
  -H 'Authorization: Bearer <YOUR_KEY>' \
  -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"eth_getBlockByNumber","params":["latest",false]}'

Receipts — root-verified at the tip, available ~200ms after the block:

curl -s https://8-232-23-170.sslip.io/v1/evm/1 \
  -H 'Authorization: Bearer <YOUR_KEY>' \
  -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":2,"method":"eth_getTransactionReceipt","params":["0x<TX_HASH>"]}'

viem

import { createPublicClient, http } from 'viem'
import { mainnet } from 'viem/chains'

const client = createPublicClient({
  chain: mainnet,
  transport: http('https://8-232-23-170.sslip.io/v1/evm/1', {
    fetchOptions: { headers: { Authorization: 'Bearer <YOUR_KEY>' } },
  }),
})

const block = await client.getBlockNumber() // served hot from memory

Ponder and other standard JSON-RPC indexers work with zero code change — point the RPC URL at the endpoint and set the header.
