How this service works
USDC pay-per-call APIs for AI agents via the x402 protocol (v2, exact, Base mainnet). Send a request, receive HTTP 402 with payment requirements, pay with @x402/fetch or any x402 client, retry with the PAYMENT-SIGNATURE header.
Output
Returns a JSON object with the token contract address, chain, a numeric risk_score (0-100), a risk_level label (e.g. 'low', 'medium', 'high'), an array of risk flags each with a code, detail, and severity, a list of data sources with availability status, and a data_quality field indicating how complete the analysis is.
Example use cases
Pre-swap token safety check
“Before I swap into this token, can you check the risk score for contract 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA on Base and let me know if it has any scary flags like honeypot or proxy contract issues?”
DeFi portfolio risk audit
“I'm building a DeFi portfolio and want to vet a few tokens — start by checking the risk level of 0x4200000000000000000000000000000000000006 on Ethereum and tell me what risk flags come up.”
Automated token screening for a trading bot
“My agent is about to buy a new token on Base — run a token risk check on contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 and only proceed if the risk level is low.”
Technical details
Endpoint
POSThttps://call402.com/api/token-risk-summary?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, structured risk assessment of a specific ERC-20 token contract on Base or Ethereum — especially in agentic workflows where autonomous token screening, pre-swap safety checks, or portfolio vetting are required. It is well-suited for AI agents that can handle x402 micropayment flows natively and need a single, low-cost ($0.05 USDC) per-call signal rather than building their own on-chain analysis pipeline.
Side effects
- Invalid or non-existent contract address returns error or empty flags
- Unsupported chain value causes validation error
- HTTP 402 returned on first call requiring x402 payment before retry
- Insufficient USDC balance prevents payment and blocks the call
- Token with no on-chain data returns degraded data_quality field
- Network congestion on Base mainnet may delay payment confirmation
