Base ERC-20 token facts and risk flags

$0.01 per call · failed calls are never charged · no account or API key needed

Live on-chain facts for any ERC-20 token on Base: name, symbol, decimals, total supply, owner address and whether ownership is renounced, paused state, proxy detection (EIP-1967 and minimal proxy) with implementation and admin addresses, and bytecode heuristics for mint, pause, blacklist and fee-setter functions. Use for token due diligence and rug-pull or honeypot screening before a swap.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/token?address=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/token?address=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913&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.
