How this service works

Pay-per-call HTTP APIs, paid with x402 in USDC on Base (eip155:8453): agentkit, api-change-check, basedue, basewatch, chainread, check-sanctions, chgwatch, company-facts, composite, edgar, feednews, pageaudit, solcheck, token-dd, txpreflight, walletcheck, webmd, webread, websearch, x402index. Each operation describes its service.

Output

Returns a JSON object with a numeric risk score (0-100), a verdict string (e.g. CAUTION, SAFE, DANGER), an array of risk flags each with a code and severity level, the chain queried, and the contract address analyzed. Also includes metadata about the payer address and price paid.

Example use cases

Pre-trade token safety screening

“Before I swap into this token, can you run a risk check on contract 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA on Base? I want the risk score and verdict so I know if it's safe.”

Detecting rug pull risk in new listing

“There's a new token that just listed — contract address 0x4200000000000000000000000000000000000006 on Base. Can you analyze it for rug pull flags or dangerous ownership concentration?”

DeFi protocol token vetting

“I'm considering adding liquidity to a pool using this Ethereum token at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 — can you score its contract risk and tell me if there are any high-severity flags?”

When to prefer

Choose this endpoint when you need a quick, paid-per-call risk verdict on a specific ERC-20 token contract on Base or Ethereum. It is purpose-built for token due diligence with structured flag codes and severity levels, making it suitable for automated DeFi agents that need to gate transactions on risk thresholds. Prefer this over generic blockchain explorers when you need a machine-readable risk score rather than raw contract data.

Side effects

Invalid or non-contract address returns an error or empty flags
Unsupported chain value (not 'base' or 'ethereum') causes validation failure
Address not found on specified chain may return null or empty response
Payment failure via x402 protocol blocks the request entirely
Rate limiting or network timeout on-chain data fetch
