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 httpay-xyz-api-gateway-basescan-base-chain-explorer-1dce4328 -d '<json body>'
```

Example prompt: Look up the transaction details and status for this Base chain tx hash 0xabc123... using BaseScan, and also tell me the current token balances for wallet 0xdef456... on Base.

## When to prefer this

Use this endpoint when an agent needs to query Base chain (Coinbase's L2) blockchain data without holding a BaseScan API key, paying only per call via x402 USDC micropayments. Prefer over direct BaseScan API when you want keyless, pay-as-you-go access to Base chain explorer data.

## Known failure modes

- Payment failure if insufficient USDC balance for x402 micropayment
- Invalid BaseScan API path returns 404 or BaseScan error
- Rate limiting from underlying BaseScan API
- Invalid address or tx hash returns BaseScan error response
- Gateway timeout if BaseScan is slow to respond
- Missing required BaseScan parameters return API error
