Example use cases
Example prompt
“Can you run a full onchain risk check on this Base token contract — 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 — and tell me if there are any dangerous controls, proxy patterns, or rug pull signals I should know about before trading it?”
Technical details
Endpoint
GEThttps://xx402.icu/x402/api/base-token-contract-riskWhen to prefer
Use this endpoint when you need a structured, per-contract onchain risk report for a specific Base ERC20 token — especially before trading, investing, or integrating a token. Prefer this over generic token info APIs when you specifically need contract control analysis, proxy detection, selector heuristics, and risk scoring in a single call for the Base chain.
Side effects
- Invalid or malformed token_address (not a 0x 40-char hex) returns 400 error
- Token contract not deployed on Base returns empty or error response
- Payment not attached or insufficient USDC triggers 402 Payment Required
- Contract is an EOA (not a smart contract) may return limited or null analysis
- Rate limiting or provider downtime returns 5xx error
