How this service works
Paid Base token, wallet, DeFi, chain-read, x402 buyer/seller discovery, and specialized Bitcoin 15-minute Up/Down prediction-market data packets for autonomous agents and risk tools.
Output
A JSON object containing a diligence decision verdict (buy/review/avoid), structured risk breakdown, liquidity pair data, on-chain transfer flow analysis, holder sketch, contract risk indicators, DeFi exposure plan, priority/review/avoid queues, agent buy ticket, token evidence matrix, and source status — all grounded in recent on-chain data from the Base network.
Example use cases
Pre-trade token safety screening
“Before I swap into this Base token at 0x4200000000000000000000000000000000000006, can you pull the full due diligence report — check the last 2000 blocks, return up to 10 liquidity pairs, and give me a clear buy or avoid verdict?”
DeFi risk dashboard for agent portfolio
“I'm building an automated DeFi risk monitor — run a token diligence check on 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base with a 500-block window and show me the risk breakdown, holder sketch, and contract risk score.”
Rug pull detection before liquidity provision
“I'm about to add liquidity to a pool on Base using token 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA — can you do a quick diligence check over the last 1000 blocks, return up to 5 liquidity pairs, and flag any contract risks or red flags?”
Technical details
Endpoint
GEThttps://x402.xx402.icu/api/base-token-diligence?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need comprehensive on-chain due diligence on a specific Base ERC20 token before trading, investing, or providing liquidity — especially when you want a structured verdict (buy/review/avoid) backed by contract risk, liquidity, holder, and flow evidence. Prefer this over generic block explorers or price APIs when the goal is autonomous agent risk decision-making on Base chain tokens.
