Arbitrum One ERC-20 token info

$0.003 per call · failed calls are never charged · no account or API key needed

Look up the name, symbol, decimals and total supply of an ERC-20 token contract on Arbitrum One, live from the contract. Use to identify an unknown token address or to format raw amounts; for a holder's balance use arb_token_balance. Input is the token's 0x contract address; an address that is not an ERC-20 contract returns 422, uncharged.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/arb/token-info?token=0xaf88d065e77c8cC2239327C5EDb3A432268e5831"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/arb/token-info?token=0xaf88d065e77c8cC2239327C5EDb3A432268e5831&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum, Monad, World Chain or Tempo) and retries.
