Heuristic wallet risk indicators, balances and account nonce on Base

$0.02 per call · failed calls are never charged · no account or API key needed

Returns a heuristic high/medium/low address risk tier, named flags, ETH balance, holdings of 4 major tokens (USDC, WETH, cbBTC, DAI), and the Base EVM account nonce. Per-token risk is unknown because token contracts are not audited here. For EOAs the nonce counts outgoing transactions only, not full history. Address type is reported separately and does not affect the balance/nonce-based risk tier. Use to screen an address before paying it.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/wallet-audit?address=0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/wallet-audit?address=0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045&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.
