     Content-Type: application/json

DESCRIPTION

Reads ERC-20 token metadata: name(), symbol(), decimals(), and totalSupply() in parallel via public RPC on Base, Ethereum, Arbitrum, Optimism, Polygon, BSC, and Avalanche. Robust to non-standard tokens that return bytes32 instead of string (MakerDAO MKR pattern is decoded). Returns formatted total supply when decimals are present, plus a chain-appropriate block explorer URL. Use it for token info, token symbol lookup, token decimals, total supply, or as a multi-chain ERC20 reader.

chainstringChain name the token lives on (Base, Ethereum, Arbitrum, Optimism, Polygon, BSC, Avalanche).
chain_idstringEVM chain ID for the network the lookup ran against.
tokenstringERC-20 contract address that was queried, echoed back checksummed.
blockstringBlock number the name/symbol/decimals/totalSupply reads were resolved against.
namestringToken name from name(), with bytes32 fallback decoded for non-standard tokens like MKR.
symbolstringToken symbol from symbol(), with bytes32 fallback decoded for non-standard tokens.
decimalsstringDecimals from decimals() as a stringified integer (e.g. '18', '6').
total_supply_rawstringRaw totalSupply() return value as a base-units integer string, no decimal scaling applied.
total_supplystringHuman-formatted total supply scaled by decimals, omitted if decimals weren't readable.
explorer_urlstringBlock explorer link for the token on its chain (Basescan, Etherscan, Arbiscan, etc.).
EXAMPLEStwo ways to call
EXAMPLE 1 · curl
curl -X POST https://x402.agentutility.ai/erc20-metadata \
  -H 'Content-Type: application/json' \
  -d '{ }'
first response = 402 Payment Required with payment requirements; sign + retry with X-PAYMENT.
EXAMPLE 2 · mcp
# Install the MCP package for this endpoint's cluster
npx -y @agentutility/mcp-<cluster>

# Required: EVM private key with USDC on Base
export X402_PRIVATE_KEY=0x...

# Then call the erc20-metadata tool from your MCP-aware agent.
MCP server handles payment automatically — your coding agent just calls the tool by name.
