Listed in PayAI
Pay-per-call Base mainnet JSON-RPC, no API key, no account: GET ?method=eth_call¶ms=[...] (params = URL-encoded JSON array) or POST a standard JSON-RPC body. POST a batch of up to 10 calls for ONE $0.002 payment (vs $0.005 per call at other x402 RPC gateways). Read + broadcast 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, web3_clientVersion. Failover across 7 public Base RPCs (drpc, publicnode, mainnet.base.org, tenderly, meowrpc, blastapi, llamarpc); upstream outage = 502 = not charged. Response is a plain JSON-RPC 2.0 result so any viem/ethers client works. When to call: your agent needs a raw Base read or to broadcast a signed tx without running or renting a node.

# 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 9 tracked endpoints. Unknown usage is left out, not counted as zero.
