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 data about the most recently mined Ethereum block, including the block number, hash, timestamp, transaction list or count, miner address, gas used, and other standard Ethereum block fields.
Example use cases
Real-time Ethereum block monitoring
“Keep me posted on the current Ethereum block number — I want to know the latest block height and when it was mined.”
On-chain event timing verification
“I need to verify whether a transaction could have been included in the latest Ethereum block — can you pull the most recent block data including its timestamp and transaction count?”
DApp synchronization checkpoint
“My app needs to sync with the Ethereum network — fetch the latest block so I can use its hash and number as a checkpoint.”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/ethereum/block/latest?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, pay-per-call lookup of the latest Ethereum block without maintaining your own Ethereum node or paying for a full RPC subscription. Ideal for lightweight agents that only need occasional block queries and want to pay in USDC micro-transactions via x402.
Side effects
- Network or node unavailability causing a 503 or timeout
- Payment failure or insufficient USDC balance returning a 402 response
- Rate limiting if too many requests are made in quick succession
- Stale or slightly delayed block data due to node sync lag
- Malformed request body causing a 400 validation error
