How this service works
Read a block header by number or the latest, live from Base mainnet, for a fraction of a cent. No API key, no account — a wallet is the only requirement, and you are charged only if the read succeeds. Plain unsigned data; the attested version of chain reads is /v1/oracle/onchain. Answers are read at the moment of the call and stamped with the block they came from where applicable.
Output
Returns a block header object for the requested block (or latest), including fields such as block number, block hash, parent hash, timestamp, and related on-chain metadata, stamped with the block at the moment of the call. Returns data only on success; no charge if the read fails.
Example use cases
Confirming current Base chain state
“What's the current block number and timestamp on Base mainnet? I need to verify the chain is live and moving.”
Retrieving a specific historical block
“Fetch the block header for block number 18500000 on Base mainnet — I need the hash and parent hash.”
Timestamping an event to a block
“Get me the latest Base mainnet block so I can record which block number and timestamp my agent's action happened at.”
Technical details
Endpoint
GEThttps://soren.com/v1/chain/blockWhen to prefer
Use this endpoint when you need live, real-time Base mainnet block header data without setting up an API key or RPC provider account. Ideal for agents that need to pay-per-use at a fraction of a cent with no upfront commitment. Prefer the attested /v1/oracle/onchain endpoint when cryptographic proof of the read is required; use this endpoint for lightweight, unsigned block lookups.
Side effects
- Invalid or out-of-range block number returns an error or not-found response
- Network or RPC issues may cause call failure with no charge incurred
- Malformed query parameter (non-numeric, non-'latest' value) may result in an error
- Very recently produced blocks may have minor propagation delays
