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.
Example use cases
Cross-chain vault research for a portfolio
“Show me the DeFi vault summary for ETH and WBTC across all supported networks — I want to see what's available on Base and Arbitrum.”
Token DeFi landscape before investing
“Before I allocate funds, can you get me the current DeFi summary for USDC and ETH so I can see what vaults and networks are active?”
Automated DeFi monitoring for agent workflow
“Every hour, fetch the DeFi summary for ETH, USDC, and WBTC and flag any new vaults or network changes that appear in the results.”
Technical details
Endpoint
GEThttps://coinop.publicvm.com/api/v1/market/defi-summary?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
