Delx Base Contract Code
x402
Delx Base Contract Code is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).
Checks whether a Base network address is a smart contract and returns its bytecode size via eth_getCode.

How this service works
Check if a Base address is a contract and return bytecode size for $0.001 USDC via eth_getCode. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.
Output
Returns whether the given Base address has deployed contract bytecode, the size of that bytecode in bytes, and the raw bytecode or a summary, effectively confirming EOA vs. contract status via eth_getCode.
Example use cases
Verify contract before DeFi interaction
“Before I interact with this Base address 0xabc123..., can you check whether it's actually a deployed smart contract or just a regular wallet?”
Audit unknown address in transaction
“I just received a transaction from 0xdeadbeef... on Base — can you tell me if that's a contract address and how large its bytecode is?”
Screen addresses in token distribution
“I'm about to send tokens to 0x5678efgh... on Base — check if it's a smart contract so I know whether it might be a proxy or vault.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/base-codeWhen to prefer
Use this endpoint when you need a fast, paid, agent-ready single-call lookup to determine if a Base L2 address is a smart contract, especially when you want to avoid managing your own RPC node or handling eth_getCode directly. Prefer this over raw RPC calls when building autonomous agents that need on-chain address classification with minimal infrastructure setup.
Side effects
- Invalid or malformed Base address returns an error
- Address exists but has no code (EOA) — returns zero bytecode size
- Network or RPC connectivity issues returning a timeout
- Payment failure if USDC balance is insufficient for the $0.001 fee
- Non-Base chain addresses may return incorrect or empty results
