Technical details
Endpoint
GEThttps://appearing-clinics-show-wrote.trycloudflare.com/ethereum-token-balance-sampleWhen to prefer
Use this endpoint when you need a real-time ERC-20 token balance for any Ethereum mainnet token (USDC, DAI, LINK, etc.) given a token contract address and an owner wallet address. Prefer this over general blockchain explorers when you need a direct, low-latency programmatic balance lookup without scraping or parsing HTML. It is especially suitable for DeFi agents, portfolio trackers, or pre-transaction checks.
Side effects
- Invalid or malformed token contract address returns an error or zero balance
- Invalid or malformed owner wallet address returns an error
- Non-ERC-20 contract address may return unexpected results
- Network or node connectivity issues may cause timeouts
- Rate limiting may apply on repeated free sample calls
