GET /v1/chain/supply

live

Read an ERC-20 total supply with symbol, decimals and a formatted amount, live from Base mainnet, for a fraction of a cent.

Answers are read at the moment of the call and stamped with the block they came from wher…

Verdict: live. The unpaid GET reached a valid 402 (confirmed by the re-probe of 2026-10-01).
