# Vibes-Coded Base ERC-20 Transfer Log Lookup

> Vibes-Coded Base ERC-20 Transfer Log Lookup is a paid API for AI agents from vibes-coded.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-11-02).

Fetches on-chain ERC-20 token transfer logs for a given contract on the Base network, returning decoded transfer events with amounts, addresses, and block numbers.

## 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 vibes-coded-base-erc-20-transfer-log-lookup-ae759333 -d '<json body>'
```

Example prompt: Pull the recent ERC-20 transfer logs for contract 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913 on Base and show me who sent tokens to whom, the amounts, and the transaction hashes.

## When to prefer this

Choose this endpoint when you need decoded, human-readable ERC-20 transfer logs specifically from the Base L2 network, especially for USDC or other Base-native tokens, without setting up your own node or indexer. It is pay-per-call ($0.02 USDC via x402) and well-suited for agents performing one-off audits, payment verification, or on-chain analytics without a subscription.

## Known failure modes

- Invalid or non-ERC-20 contract address returns empty transfer list or error
- Contract address on a different network (not Base) returns no results
- Malformed wallet address filter causes 400 bad request
- Payment not received in USDC triggers HTTP 402 before processing
- Rate limiting or node timeout may return partial or empty results

## How this service works

Pay-per-call JSON for AI agents: skill search, listing optimization, install plans, productization, and artifact risk scoring. HTTP 402 → USDC. Full skill marketplace on-site.

## Output

Returns a JSON object with a list of decoded ERC-20 transfer events, each containing sender address, recipient address, token amount (human-readable and raw), transaction hash, and block number, along with the contract address, decimal precision, and a generated_at timestamp.
