How this service works
Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.
Output
Returns the latest block details from the SEI blockchain, including block number (height), block hash, timestamp, and potentially transaction count and validator information for that block.
Example use cases
Real-time SEI block monitoring
“Keep checking the SEI blockchain and tell me the latest block number every time a new one is produced — I want to monitor chain activity.”
SEI chain health verification
“Is the SEI blockchain actively producing new blocks? Grab the latest block and tell me the block number and when it was created so I can confirm the chain is live.”
DApp sync status check
“My dapp needs to know the current SEI block height to sync from — what's the most recent block number and hash on SEI?”

Endpoint
POSThttps://phantom-api-omega.vercel.app/api/sei/block/latestWhen to prefer
Use this endpoint when you need real-time, up-to-date block data specifically from the SEI blockchain network. Prefer it over generic blockchain explorers when you need programmatic, pay-per-call access without subscription overhead and when low-latency on-chain data is critical for agent workflows.
