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
A JSON object containing the transaction hash, block number, block timestamp (UTC), chain name and chain ID, success flag, confirmation count, a list of ERC-20 transfers (each with from/to addresses, token contract address, symbol, decimals, raw and formatted amount, and log index), and a list of ERC-721 transfers.
Example use cases
Verify crypto payment receipt
“Check transaction 0x71aa55e3a2cbfe57d1707997a21f13d7026e17e7f3536c24e86f14144fffc67d on Base and confirm whether a USDC payment went through, how much was sent, and who received it.”
Audit ERC-20 transfers on Ethereum
“Pull up the token transfer details for tx hash 0xabc123...def456 on Ethereum — I want to know the token symbol, the amount, and the sender and recipient addresses.”
Check NFT transfer on Polygon
“Look up transaction 0x9f8a...1234 on Polygon and tell me if any ERC-721 NFTs were transferred, and if so which token IDs and to which wallet.”
Technical details
Endpoint
GEThttps://ai-policy-kit.moneymaker-ai.workers.dev/api/token-transfers?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to decode and inspect ERC-20 or ERC-721 token transfers from a known transaction hash across major EVM chains (Base, Ethereum, BSC, Arbitrum, Optimism, Polygon, Gnosis, Celo). It is ideal for payment verification, audit trails, and post-transaction analysis where you already have the tx hash. Prefer this over a block explorer scrape when you need structured, machine-readable transfer data.
Side effects
- Invalid or malformed transaction hash returns an error
- Unsupported chain name returns a validation error
- Transaction not yet indexed or too recent may return no results or stale confirmations
- Transaction exists but contains no token transfers — empty transfer arrays returned
- Network timeouts on RPC calls may result in service errors
