## 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 x402-bazaar-base-wallet-activity-48a6f4f6 -d '<json body>'
```

Example prompt: Pull up the latest transactions for Base wallet 0xAbCd1234... and show me the hash, time, who sent it, who received it, the ETH value, and whether each one succeeded.

## When to prefer this

Choose this endpoint when you need a quick, affordable ($0.01) lookup of recent on-chain activity for a specific Base (eip155:8453) wallet address and want structured transaction data (hash, time, from/to, value, success) powered by Covalent. Ideal for agents monitoring wallet behavior, auditing addresses, or surfacing transaction history without building a direct Covalent integration.

## Known failure modes

- 402 Payment Required returned first — agent must pay $0.01 USDC on Base to 0x973a31858f4d2125f48c880542da11a2796f12d6 and retry
- Invalid or malformed Base address returns an error
- Address with no transaction history returns empty result set
- Covalent data lag may mean very recent transactions are not yet indexed
- Network congestion on Base may delay data freshness

## How this service works

The latest transactions for a Base address — hash, time, from/to, ETH value, success — via Covalent. For agents tracking what a wallet is doing. Paid via x402: $0.01 in USDC on Base (eip155:8453) to 0x973a31858f4d2125f48c880542da11a2796f12d6. Returns 402 with payment requirements; pay and retry.

## Output

A list of recent transactions for the given Base address, each containing the transaction hash, timestamp, from and to addresses, ETH value transferred, and a success/failure status flag — sourced from Covalent.
