๐Ÿ†• totalSupply for any Base token, returned raw and scaled by its decimals, alongside the name and symbol. When a contract doesn't declare decimals the answer assumes 18 and marks that it assumed โ€” a silent guess here quietly moves every downstream number by orders of magnitude. Non-token addresses answer found:false.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.002.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://402.com.tr/api/x402/token-supply?token=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
