## 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 crypto-shark-bazaar-chain-token-transfers-a3e463b8
```

Example prompt: Pull the recent token transfers on Base for wallet address 0xAbCd1234... — I want to see what's been moving in and out.

## When to prefer this

Choose this endpoint when you need lightweight, low-cost ($0.001 USDC) on-chain token transfer lookups on the Base network via the x402 micropayment protocol, especially for autonomous agents that need programmatic blockchain data access without a heavyweight indexer subscription.

## Known failure modes

- Invalid or malformed wallet/contract address returns an error or empty result
- Unsupported network or property filter yields no data
- Rate limiting or payment failure (x402) blocks the request
- Missing required properties parameter may return unexpected results
- Network congestion or node delays may cause stale or incomplete data

## How this service works

Low-cost x402 blockchain primitives, market intelligence, and AI utilities for autonomous agents
