How this service works
Live Base and Ethereum RPC for AI agents: block tip, balances, transactions, and ENS. $0.001 USDC per call on Base.
Output
A JSON response containing the current block number as a hex string (e.g. '0x12a05f2'), along with metadata: the RPC endpoint used, the network queried (base or ethereum), the cost in USDC ($0.001), and a unique request ID for tracing.
Example use cases
Confirm chain liveness before transaction
“Before I submit my transaction, can you check what the current block number is on Base so I know the chain is live and moving?”
Monitor Ethereum block progress
“Keep an eye on the Ethereum block number for me — what block are we at right now on Ethereum mainnet?”
Build block-height triggered automation
“I need to know the current block height on Base to decide whether my on-chain event has been included yet — can you grab the latest block number?”
Technical details
Endpoint
GEThttps://joe-evm-rpc.marnick-yezo.workers.dev/api/chain/block-numberWhen to prefer
Choose this endpoint when your agent needs to know the current block tip on Base or Ethereum mainnet with minimal setup — it wraps the raw RPC call behind a simple REST GET with x402 micropayment, so there's no need to manage provider API keys or configure a full Web3 connection. Prefer it for lightweight chain-height polling, liveness checks, and block-based triggers in AI agent workflows.
Side effects
- Invalid or unsupported network value returns an error (only 'base' and 'ethereum' are accepted)
- Network RPC unavailability causes a 5xx or timeout response
- x402 payment failure (insufficient balance or wallet misconfiguration) results in a 402 Payment Required error before the RPC call is made
- Rate limits or worker capacity issues may cause transient 429 or 503 errors
