How this service works
一个人的思考、创作与成长记录。关于生活、技术、商业和一切有趣的事。
Output
A JSON object containing: ethUsd (current ETH price in USD as a float, e.g. 3500.42), blockNumber (latest block number on the Base chain, e.g. 28123456), and baseRpcHealthy (boolean indicating whether the Base RPC endpoint is operational).
Example use cases
Real-time ETH price check
“Can you grab the latest ETH/USD price for me right now?”
Base network health monitoring
“Check whether the Base RPC is currently healthy and tell me what block it's on.”
Crypto dashboard snapshot
“I need a quick snapshot — current ETH price, latest Base block number, and whether the Base RPC is up. Pull that for me.”
Technical details
Endpoint
POSThttps://leoshi-blog.vercel.app/api/market?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, low-cost combined lookup of ETH/USD price AND Base chain status in a single call. It is ideal for lightweight monitoring agents or DeFi dashboards that need to confirm both market price and blockchain health together without querying multiple data sources separately.
Side effects
- RPC node unavailable — baseRpcHealthy may return false or call may fail
- Price feed outage — ethUsd may be stale or missing
- Network timeout — endpoint may not respond if the Vercel deployment is cold or overloaded
- Invalid/no response body if payment is not processed correctly via x402 protocol
