How this service works
Generate an AI_POLICY.md and a pull request template with an AI-disclosure section for your open-source repo. Free, runs in your browser.
Output
Returns a JSON object with per-chain breakdown (block number, nonce, native ETH balance, stablecoin token balances with symbols and amounts), total aggregated USDC and USDT balances, the queried wallet address, and a list of chains the wallet is active on.
Example use cases
Pre-payment wallet balance check
“Before we send the invoice payment, can you check if wallet 0xAbC123...def456 has at least 50 USDC available on Base?”
Portfolio snapshot for DeFi dashboard
“Pull the current ETH and stablecoin balances for 0x5b4Ca59741DE12DC212982b342392a063492a021 so I can update my portfolio tracker.”
Verify wallet activity before airdrop
“Is wallet 0x9f8e7d6c5b4a3210fedcba9876543210abcdef12 actually active on Base, and what tokens does it hold right now?”
Technical details
Endpoint
GEThttps://ai-policy-kit.moneymaker-ai.workers.dev/api/wallet-snapshot?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, multi-chain token balance snapshot for an EVM wallet address, especially when you need USDC/USDT stablecoin totals aggregated across chains. It is particularly suitable for pre-payment checks, airdrop eligibility verification, or lightweight portfolio monitoring without needing a full blockchain indexer.
Side effects
- Invalid or malformed 0x address returns an error
- Address not active on any supported chain returns empty balances
- Rate limiting or payment failure (402) if USDC payment not attached
- Network timeout if the underlying RPC node is slow
- Chain not supported returns missing chain data
