## 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 phantom-api-base-network-token-transfers-8757541e -d '<json body>'
```

Example prompt: Show me all token transfers for wallet 0xAbC...1234 on Base, going back to block 10000000, sorted ascending, and limit it to 50 results for the USDC contract 0x833589...

## When to prefer this

Use this endpoint when you need historical token transfer data specifically on the Base network with fine-grained control over block range, pagination, sort order, and contract filtering. Prefer this over generic blockchain explorers when you need programmatic, structured JSON output suitable for agent consumption and pay-per-call pricing makes sense for your volume.

## Known failure modes

- Invalid owner address format returns an error
- Unknown pageKey causes pagination failure or empty results
- fromBlock greater than toBlock returns an error or empty set
- maxCount exceeding API limits may be capped or return an error
- Missing required fields (owner or contractAddresses) may result in empty or error response
- Network downtime or upstream indexer outage returns 5xx error

## How this service works

## Output

A list of token transfer records on the Base network, each including sender, recipient, token contract address, amount, block number, and transaction hash. Supports pagination via a pageKey for large result sets.
