How this service works
Complete ERC20 token state in one call: name, symbol, decimals, total supply (raw + formatted), wallet balance, and allowance. Collapses four onesource chain calls (total-supply + erc20-balance + allowance + contract — 155–229 payers each) into one $0.007 payment — 36% below the $0.011 combined chain. Supports Ethereum (default), Base, Polygon, Arbitrum. No API key required.
Output
Returns ERC20 token metadata (name, symbol, decimals, total supply) for the given contract. If a wallet address is provided, also returns the wallet's token balance. If both wallet and spender addresses are provided, also returns the allowance the spender has on the wallet's tokens.
Example use cases
Example prompt
“Pull a snapshot of the ERC20 token at contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum — give me the name, symbol, total supply, and also check the token balance for wallet 0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe.”
Technical details
Endpoint
GEThttps://the-stall.intuitek.ai/cap/erc20-snapshotWhen to prefer
Use this endpoint when you need on-chain ERC20 token data (supply, balance, allowance, metadata) across major EVM chains without requiring an API key or account — ideal for AI agents making microtransaction-priced blockchain data queries via x402/USDC payment on Base mainnet.
Side effects
- Invalid or malformed contract address returns an error
- Contract address is not an ERC20 token (e.g. ERC721) — may return zero or error
- Unsupported network value returns validation error
- Wallet address required when checking allowance but not provided — returns error
- RPC node unavailability may cause timeouts or empty responses
