How this service works
Latest Solana blockhash + lastValidBlockHeight for building and signing transactions (confirmed, cached <=1 s).
Output
Returns a JSON object containing two fields: 'blockhash' (a base58-encoded string representing the latest confirmed Solana blockhash) and 'lastValidBlockHeight' (an integer indicating the last block height at which a transaction using this blockhash will still be accepted by the network). Data is cached for up to 1 second at confirmed commitment level.
Example use cases
Sign and submit a Solana transaction
“I'm about to build and sign a Solana transaction — can you get me the latest blockhash and lastValidBlockHeight so I can include them before broadcasting?”
Check Solana blockhash freshness for transaction validity
“What's the current Solana blockhash and how many blocks do I have left before it expires? I want to make sure my transaction won't get rejected for using a stale blockhash.”
Automate Solana transaction batching pipeline
“My transaction batching bot needs the latest Solana recent blockhash and lastValidBlockHeight every time before it submits a batch — can you pull that now?”
Technical details
Endpoint
GEThttps://mintintel.35-171-220-195.sslip.io/v1/sol/blockhash?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, low-cost, pre-cached Solana blockhash and lastValidBlockHeight for transaction construction — especially in automated pipelines where making a raw Solana RPC call would add latency or complexity. At $0.001 USDC per call, it is cheaper than maintaining your own RPC node for this single query. Prefer it over direct RPC when you need a simple one-call solution with caching guarantees and confirmed commitment semantics.
Side effects
- Stale cache: if the cache hasn't refreshed within 1 second, the blockhash may be slightly behind the live chain tip
- Network unavailability: if the upstream Solana RPC is unreachable, the endpoint may return an error or timeout
- Payment failure: missing or invalid x402 payment header results in a 402 Payment Required response
- Rate limiting: excessive requests may be throttled beyond the cached refresh window
