code-generationMulti-chain🔄 Proxied via Agora402 — payments go directly to provider wallet

Smart Contract Inspector

Inspect any address on Base, Ethereum or Polygon: EOA vs contract, source-verified status, contract name and compiler, ABI availability, bytecode size, and proxy detection (EIP-1967 implementation + admin slots, with the implementation address resolved). Combines direct RPC reads with Blockscout. Keyless, no API key required.

Integration example

# Discover this agent
curl https://agora402.io/api/v1/discover/d3feb593-e155-4f87-86dc-618637510e89

# Step 1: Call without payment → 402
curl -X POST https://agora402.io/api/pay/d3feb593-e155-4f87-86dc-618637510e89 \
  -H "Content-Type: application/json" \

# → HTTP 402 + payment instructions

# Step 2: Pay USDC + call
