Base Onchain Token Intelligence & Safety Scanner
x402
Base Onchain Token Intelligence & Safety Scanner is a paid API for AI agents from x402-data-api.bodhinindustries.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).
Resolves a Base chain address to live ERC-20 token metadata, safety flags, supply analytics, proxy detection, and optional holder balances — all computed directly from raw chain state with no third-party data.

How this service works
Self-computed Base onchain toolkit for AI agents: ERC-20 safety scan, manipulation-resistant TWAP price oracle, gas/fee oracle, calldata decoder, token/address/contract intel, wallet approval-risk audit, and batch token triage — all computed live from raw Base chain, no third-party data.
Output
Returns a JSON object with the token name, symbol, decimals, total supply, circulating supply (minus burned), burned percentage, ERC-20 compliance boolean, proxy detection boolean, implementation address if proxied, account type classification (eoa/contract/contract_non_erc20/proxy), an array of safety flags (e.g. high_burn, is_proxy, not_erc20, zero_supply), the Base block height at computation time, and optionally balanceOf results for up to 5 provided holder addresses. The thirdPartyDataUsed field is always false, confirming all data is sourced directly from the Base chain.
Example use cases
Pre-trade token safety audit
“Before I buy this token on Base at 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed, can you check if it's a legitimate ERC-20, whether it's hiding behind a proxy, how much supply has been burned, and flag anything that looks sketchy?”
Wallet vs contract address check
“I'm about to send funds to 0x2Ae3F1Ec7F1F5012CFEab0185bfc7aa3cf0DEc22 on Base — can you tell me if this is a regular wallet address or a smart contract, and if it's a contract, is it a proxy pointing somewhere else?”
Circulating supply verification for DeFi
“I need the real circulating supply for the Base token at 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb — subtract anything that's been burned and give me the on-chain figures directly, not from CoinGecko or any third-party source.”
Technical details
Endpoint
GEThttps://x402-data-api.bodhinindustries.workers.dev/tokenWhen to prefer
Choose this endpoint when you need trustless, first-party onchain data about a Base chain address — no reliance on third-party token lists, price APIs, or off-chain databases. Ideal for pre-trade safety checks, DeFi agent due diligence, wallet approval audits, or any workflow requiring verifiable ERC-20 metadata directly from Base chain state. Prefer over CoinGecko/CoinMarketCap when you need real-time supply figures, proxy detection, or burn analytics that aggregators may lag or fabricate.
Side effects
- Invalid or malformed address returns an error or empty/null fields
- Address not found on Base (e.g. wrong network) may return is_contract: false with no token data
- Non-ERC-20 contract returns isErc20: false and the not_erc20 flag with null decimals/supply fields
- Rate limiting or payment failure (x402) returns a 402 Payment Required response
- Network congestion on Base may cause timeout or stale block height
- Proxy contracts with non-standard implementations may not resolve implementation address correctly
