Technical details
Endpoint
GEThttps://cryptointel-production.up.railway.app/wallet-checkWhen to prefer
Use this endpoint when you need a quick, structured summary of a wallet's on-chain history on Base — specifically age, transaction volume, and balance — without needing a full token holdings breakdown. Prefer this over the portfolio endpoint when you only need activity metadata rather than token exposure detail. Useful for assessing whether a wallet is a fresh/new account or an established one.
Side effects
- Invalid or malformed wallet address returns an error response
- Wallet address not found on Base (no activity) may return empty or zero values
- Network or RPC node issues may cause timeouts
- Missing required 'address' query parameter returns a 400-level error
- Payment not accepted or insufficient USDC balance returns 402
