How this service works
Read an ERC-20 balance with symbol, decimals and a formatted amount — one call, no ABI work, live from Base mainnet, for a fraction of a cent. No API key, no account — a wallet is the only requirement, and you are charged only if the read succeeds. Plain unsigned data; the attested version of chain reads is /v1/oracle/onchain. Answers are read at the moment of the call and stamped with the block they came from where applicable.
Output
Returns the ERC-20 token balance for the specified holder address, including: raw balance, human-formatted amount (adjusted for decimals), token symbol, token decimals, and the block number at which the balance was read. Returns a not-found or zero-balance result if the address holds none of the token.
Example use cases
DeFi portfolio balance check
“Check how much USDC the wallet 0xaDc3A47EFbD82Ed724a0E9A3D08D5A1A8e6586fd holds on Base — use the USDC contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 and show me the balance formatted with the right decimals.”
Verify token receipt after transfer
“I just sent some tokens and want to confirm they arrived — can you read the ERC-20 balance for token contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 at address 0xaDc3A47EFbD82Ed724a0E9A3D08D5A1A8e6586fd on Base right now?”
Agent treasury monitoring
“My agent's treasury wallet is 0xaDc3A47EFbD82Ed724a0E9A3D08D5A1A8e6586fd — what's the current balance of the token at contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base mainnet, with the symbol and human-readable amount?”
Technical details
Endpoint
GEThttps://soren.com/v1/chain/erc20-balanceWhen to prefer
Choose this endpoint when you need a live, formatted ERC-20 balance from Base mainnet in a single call without writing or parsing ABI code. It is ideal for agents that need quick, human-readable token balances (symbol + formatted amount) without setting up a full Web3 stack. For attested/oracle-grade reads with cryptographic proof, use the sibling /v1/oracle/onchain endpoint instead.
Side effects
- Invalid ERC-20 contract address returns an error or zero data
- Invalid holder address format causes a request error
- Non-ERC-20 contract address (e.g. EOA or non-standard contract) may return unexpected results
- Base mainnet node unavailability causes a read failure
- Payment (x402) failure results in no charge and no data returned
- Token contract with non-standard decimals may return unexpected formatted amounts
