## 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 coinopselect-defi-summary-api-509d1e25
```

Example prompt: Can you pull the DeFi summary for ETH, USDC, and WBTC — I want to see vault info and which networks like Base, Arbitrum, and Ethereum are covered?

## When to prefer this

Choose this endpoint when you need a cross-network DeFi vault overview for specific crypto tokens (up to 10) across Base, Arbitrum, and Ethereum, and are operating in an x402-enabled payment environment on Base. Prefer it over generic block explorers when you want aggregated vault-level DeFi data rather than raw transaction history, and when per-call micropayment pricing ($0.01 USDC) is acceptable for fresh, streaming-sourced data.

## Known failure modes

- Missing or invalid x402 payment header returns 402 Payment Required
- Invalid or unsupported ticker symbols result in empty or partial vault arrays
- Exceeding the 10-symbol limit may cause request rejection or truncation
- Network or upstream data stream outages may result in empty vaults array with a stale or missing generatedAt
- Malformed queryParams (non-comma-separated symbols) may return default ETH,USDC,WBTC results instead of requested tickers

## How this service works

Paid on-chain token, wallet, contract and research data over x402 on Base.

## Output

Returns a JSON object with an array of vault data entries, an array of token symbols queried, a list of networks covered (e.g. base, arbitrum, ethereum), a source identifier (stream-1-defi/vault-monitor), an optional note, and a generatedAt ISO timestamp indicating when the data was produced.
