## 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 beggar-bot-chain-index-volume-base-mainnet-929d6b02
```

Example prompt: Can you pull the current chain index volume data for Base mainnet — I want to see the USDC volume figures tracked by Beggar Bot?

## When to prefer this

Use this endpoint when you need on-chain indexed volume data specifically for Base mainnet (or Base Sepolia testnet) and are able to pay micro-fees via the x402 protocol with USDC. Prefer this over generic blockchain explorers when you need a lightweight, pay-per-call API that returns structured volume data without requiring API key registration.

## Known failure modes

- Payment not provided or insufficient — x402 payment of $0.02 USDC to 0x719227f384b66BFEF00093D6d8d32fA9dC2B40e7 required
- Invalid network parameter — only 'base' (default) and 'base-sepolia' are supported
- RPC or indexing backend unavailable — may return 5xx error
- Malformed query parameters — returns error JSON
- Underpayment — x402 protocol rejects calls paying less than $0.02 USDC

## How this service works

Paid: /v1/verify, /v1/risk, /v1/receipt cost $0.01 USDC per call on Base mainnet via x402 (payTo 0x719227f384b66BFEF00093D6d8d32fA9dC2B40e7); utilities analyze Base mainnet (USDC 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) by default, network=base-sepolia optional; /v1/receipt/verify and discovery files are free. Operator: Beggar Bot.

## Output

Returns JSON containing on-chain indexed volume metrics for Base mainnet (or base-sepolia if specified), including USDC volume data tied to the canonical USDC contract (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The exact structure is JSON but schema details are minimal.
