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 a JSON-RPC response payload from the Base/Ethereum node, including fields such as block data, account balance in wei, transaction receipts, or contract bytecode, depending on the method called. Payment of $0.001 USDC is settled atomically via x402 before the response is delivered.
Example use cases
Check wallet balance on Base
“What's the ETH balance of wallet 0xdead...beef on the Base L2 network right now?”
Fetch block data by hash
“Pull the full block details for block hash 0xabc123... on Base — I need the timestamp, transaction count, and miner.”
Inspect smart contract code on-chain
“Retrieve the deployed bytecode for contract address 0x1234...5678 on Base so I can verify it's the right contract.”

Endpoint
GEThttps://mcp-x402.onrender.com/x402/base-rpcWhen to prefer
Choose this endpoint when you need lightweight, pay-per-call access to Base or Ethereum RPC data without managing your own node or committing to a subscription API key. Ideal for AI agents that make infrequent or burst RPC calls and want to settle costs in USDC micropayments via x402. Prefer alternatives (Alchemy, Infura free tiers) when call volume is high enough to make per-call pricing uneconomical.
Side effects
- Invalid or unsupported RPC method returns an error object
- Missing required 'method' field causes a 400-level rejection
- Block hash or address not found returns null result
- Payment failure or insufficient USDC balance blocks the response
- Network congestion on Base may cause timeouts
- Malformed address or hash causes RPC-level error
