# Mint Intel: Base ERC-20 Transfer Events

> Mint Intel: Base ERC-20 Transfer Events is a paid API for AI agents from mintintel.35-171-220-195.sslip.io, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-31).

Fetches recent ERC-20 Transfer events on Base chain for a given token contract, optionally filtered by wallet address, returning block, tx hash, from/to addresses, and token amounts.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability mint-intel-base-erc-20-transfer-events-65633b1e
```

Example prompt: Show me the last 50 ERC-20 transfers for the token at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base, but only transfers involving wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045.

## When to prefer this

Use this endpoint when you need recent Transfer event history for a specific ERC-20 token on Base chain, especially when you want to scope results to a particular wallet or a recent block window. Prefer this over Ethereum equivalents when the token lives on Base. Best suited for real-time monitoring, wallet auditing, and token flow analysis within a 2,000-block lookback window.

## Known failure modes

- Invalid or non-ERC-20 token contract address returns empty transfers or error
- Wallet address filter typo returns no results silently
- blocks parameter exceeding 2000 rejected with validation error
- Token contract with no activity in the window returns count 0 and empty array
- Payment failure (x402) if USDC not provided or insufficient balance
- RPC timeout if Base node is congested

## How this service works

ERC-20 Transfer events on Base via eth_getLogs - the newest transfers of a token, optionally only those from or to one wallet (?wallet=), window up to 2,000 blocks: block, tx hash, from, to, raw and decimal-adjusted value.

## Output

Returns a JSON object with the token address, a count of matching transfers, and an array of transfer records each containing block number, transaction hash, sender address, recipient address, raw value in wei, and decimal-adjusted human-readable token amount — ordered newest first.
