Erc20 Metadata

Reads ERC-20 token metadata: name(), symbol(), decimals(), and totalSupply() in parallel via public RPC on Base, Ethereum, Arbitrum, Optimism, Polygon, BSC, and Avalanche.

Overview

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.

How to call it

Requests are paid per call over the x402 protocol. Call the endpoint, receive a 402 Payment Required quote, then repeat the request with the signed payment header. The SDKs do both steps for you.

# 1. Ask for a quote
curl -i -X POST https://api.jarvisclaw.ai/v1/marketplace/api/erc20-metadata \
  -H 'Content-Type: application/json' \
  -d '{}'

# 2. Pay it (the SDK signs and retries for you)
curl -X POST https://api.jarvisclaw.ai/v1/marketplace/api/erc20-metadata \
  -H 'Content-Type: application/json' \
  -H 'X-PAYMENT: <signed-payload>' \
  -d '{}'
