Pay-per-call Ethereum mainnet (chain 1) JSON-RPC, no API key, no account, paid in Base USDC: GET ?method=eth_call¶ms=[...] or POST a standard JSON-RPC body; POST a batch of up to 10 calls for ONE $0.002 payment (vs ~$0.01 per call at other x402 mainnet RPC APIs). Methods: eth_blockNumber, eth_chainId, eth_call, eth_estimateGas, eth_getBalance, eth_getTransactionCount, eth_getCode, eth_getStorageAt, eth_getTransactionByHash, eth_getTransactionReceipt, eth_getBlockByNumber, eth_getBlockByHash, eth_getLogs (<=2000 blocks), eth_gasPrice, eth_maxPriorityFeePerGas, eth_feeHistory, eth_sendRawTransaction, net_version. Failover across 7 public Ethereum RPCs; outage = 502 = not charged. Plain JSON-RPC 2.0 so viem/ethers work. When to call: your agent needs an L1 read (ENS, mainnet token balance, contract state, receipt) or to broadcast a signed mainnet tx.

How to buy
This endpoint takes pay-per-call payments over x402. Call it once without paying to see its live price; any x402 client then pays and retries automatically.

# HTTP/1.1 402 Payment Required: price, asset and payTo are in the responseEstimated calls per day
Paid calls to kr-x402-mvp.kgy5612.workers.dev's tracked endpoints each day, estimated from the 30-day totals the x402 catalogues report. Each bar is the change in that 30-day total since the day before, plus the calls that left the 30-day window (taken as an average day). It is an estimate: Hagglyai does not measure or pay for these calls.
No usage reported for any of 11 tracked endpoints. Unknown usage is left out, not counted as zero.
Compared with other providers
