x402 APIPassing, checked 2 h ago

ERC-20 token profile on any major EVM chain: on-chain metadata (name, symbol, decimals, total supply) read straight from the contract, joined with live DEX market data (USD price, liquidity, 24h volume, 24h change, and the top trading pair with its DEX). Use it to price a token, check liquidity depth before a swap, or resolve an unknown contract address into a real token.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.004.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://chain.cyberwarex.com/token?address=0x4200000000000000000000000000000000000006&chain=base'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - 'https://chain.cyberwarex.com/token?address=0x4200000000000000000000000000000000000006&chain=base' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
