Bulk Token Metadata
Read ERC-20 symbol, name, decimals, and raw total supply for up to ten contract addresses using live eth_call requests.
Preview request
The preview path is rate-limited and does not charge. Production requests use the same parameters and return a standard x402 challenge when no payment signature is present.
