How this service works
Goldsky Feeds: Prediction markets and Chain datasets — prepaid balance, funds ~500 requests at 10 atomic units each
Output
Returns a JSON object containing the chain name (e.g. 'base'), the latest block number as an integer, the block's Unix timestamp, and the head_lag_seconds indicating how many seconds the indexed head trails the actual chain tip.
Example use cases
Real-time Base chain sync check
“Is the Base chain head up to date? Give me the current block number and how many seconds it's lagging behind.”
On-chain event timing reference
“I need the exact timestamp of the latest block on Base so I can correlate it with an on-chain event I'm tracking.”
Blockchain indexer health monitoring
“Keep checking the Base head block lag every minute and alert me if it goes above 30 seconds.”
Technical details
Endpoint
GEThttps://edge.goldsky.com/data/blocks/base/head?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, low-cost ($0.005/call) real-time lookup of the Base blockchain's current head block without running your own node or using a full RPC provider. It is ideal for monitoring scripts, agent health checks, or timestamping workflows that only need block number, timestamp, and lag — not full transaction data.
Side effects
- 402 Payment Required if prepaid balance is exhausted
- 503 or timeout if Goldsky indexer is temporarily unavailable
- Stale data if head_lag_seconds is elevated due to indexer sync issues
- Network errors if edge.goldsky.com is unreachable
