How this service works
Pay-per-call crypto, RWA, federal, SEC, Section 8/HUD housing, and compliance APIs via x402. Primary: USDC on Base (eip155:8453). Also accepts Global Dollar (USDG) on Robinhood Chain (eip155:4663) via sovereign X-PAYMENT-TX. Hyphen routes only (e.g. /x402/gas-tracker, /x402/pha-lookup, /x402/sec-8k). MARKETPLACE REVIEW: use free /x402/playground/* (no key, no payment). Production /x402/* returns 402 unless paid via x402 or X-Api-Market-Key / X-API-Key from seller dashboard.
Output
Returns the raw JSON-RPC response from the Ethereum node for the requested method, including fields such as balance, transaction details, block metadata, or contract return values depending on the method called.
Example use cases
Check wallet ETH balance on-chain
“What's the current ETH balance for wallet address 0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe? Call the Ethereum RPC to get the live on-chain balance.”
Look up transaction by hash
“Can you fetch the details of this Ethereum transaction — hash 0x5c504ed432cb51138bcf09aa5e8a410dd4a1e204ef84bfed1be16dfba1b22060 — and tell me its status and value?”
Fetch latest Ethereum block info
“Get me the details of the latest Ethereum block — block number, timestamp, and transaction count — using the eth_getBlockByNumber RPC call.”

Endpoint
GEThttps://mcp-x402.onrender.com/x402/eth-rpcWhen to prefer
Choose this endpoint when you need pay-per-call Ethereum RPC access without a subscription, especially when your agent stack supports x402 micropayment settlement in USDC on Base. Ideal for low-frequency on-chain lookups where a full node subscription is overkill.
Side effects
- Invalid or unsupported RPC method name returns an error response
- Malformed address or hash parameter causes a bad request error
- Payment not settled in USDC on Base results in 402 Payment Required
- Block or transaction not found returns null or empty result
- Network timeout or node unavailability causes a service error
