Venice Crypto RPC (JSON-RPC proxy)

Venice exposes a multi-chain JSON-RPC proxy billed per call. Same request shape as Alchemy / Infura — just change the base URL and pay per credit.

Endpoint	Auth	Notes
GET /crypto/rpc/networks	Bearer or SIWE	Returns { "networks": [...] } (sorted).
POST /crypto/rpc/{network}	Bearer or SIWE (x402)	Forward a JSON-RPC 2.0 request (single or batch).

Supported networks

Call GET /crypto/rpc/networks for the current list. It currently returns 23 slugs (always verify — the catalog grows):

arbitrum-mainnet    arbitrum-sepolia
avalanche-mainnet   avalanche-fuji
base-mainnet        base-sepolia
blast-mainnet       blast-sepolia
bsc-mainnet         bsc-testnet
ethereum-mainnet    ethereum-sepolia    ethereum-holesky
linea-mainnet       linea-sepolia
optimism-mainnet    optimism-sepolia
polygon-mainnet     polygon-amoy
starknet-mainnet    starknet-sepolia
zksync-mainnet      zksync-sepolia

Use the slug as :network in the proxy path.

Send a JSON-RPC request

Single call

curl -X POST https://api.venice.ai/api/v1/crypto/rpc/ethereum-mainnet \
  -H "Authorization: Bearer $VENICE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_chainId","params":[],"id":1}'

{ "jsonrpc": "2.0", "id": 1, "result": "0x1" }

Batch (up to 100 calls)

curl -X POST https://api.venice.ai/api/v1/crypto/rpc/base-mainnet \
  -H "Authorization: Bearer $VENICE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '[
    {"jsonrpc":"2.0","method":"eth_chainId","params":[],"id":1},
    {"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":2}
  ]'

A single unsupported method in a batch ⇒ the entire batch fails with 400.

Drop-in with viem / ethers

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

const client = createPublicClient({
  chain: mainnet,
  transport: http('https://api.venice.ai/api/v1/crypto/rpc/ethereum-mainnet', {
    fetchOptions: { headers: { Authorization: `Bearer ${process.env.VENICE_API_KEY}` } },
  }),
})
