How this service works
High-speed API suite for AI processing, web scraping, and smart data utilities across 57+ blockchain networks. Pay-per-call via x402.
Output
Returns the latest block information from the specified blockchain network, including block number, hash, timestamp, and related metadata for the chain tip.
Example use cases
Monitor blockchain tip for alerting
“Keep checking the latest block on the Polygon network and let me know whenever a new block is produced so I can track chain activity.”
Verify chain liveness before transaction
“Before I submit my transaction, can you check the latest block on Ethereum to confirm the chain is live and producing blocks normally?”
Log current block height for audit
“Fetch the latest block number and timestamp from the BNB Chain right now and log it so I have a record of the blockchain state at this moment.”

Endpoint
POSThttps://synapse-api-brown.vercel.app/api/adi/block/latestWhen to prefer
Choose this endpoint when you need real-time latest block data across a wide range of blockchain networks (57+) without maintaining your own node infrastructure. It is especially useful for agents that need to check chain liveness, retrieve current block height, or anchor a timestamp to a specific block, particularly when paying per-call via x402 USDC is acceptable and you want multi-chain coverage from a single API.
Side effects

- Malformed request body (missing required fields) returns a 400-level error
- Payment not provided or insufficient USDC results in a 402 Payment Required response
- Network or upstream blockchain node timeout returns a 5xx error
