How this service works
Base latest block number + timestamp — a chain-head freshness probe. Pay-per-call via x402.
Output
Returns a JSON object with the current Base network block number (e.g. 49280291), the Unix timestamp of that block, an ISO 8601 timestamp string, the network name ('base'), and an asOf field indicating when the data was fetched.
Example use cases
Blockchain freshness health check
“Can you check what the latest block number and timestamp are on Base so I can confirm our on-chain data feed isn't stale?”
Timing an on-chain transaction window
“What's the current block number and timestamp on Base? I want to make sure I'm submitting my transaction at the right time.”
Automated chain liveness monitor
“Every 30 seconds, grab the latest Base block number and timestamp and alert me if the chain hasn't produced a new block in over 2 minutes.”
Technical details
Endpoint
POSThttps://fiatdock.com/v1/chain/blockWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call chain-head freshness probe for the Base network specifically — ideal for monitoring liveness, anchoring timestamps, or validating that downstream on-chain data is current. Prefer this over a full node RPC call when you want a simple REST interface with no node setup and only pay $0.001 per call.
Side effects
- Base RPC node unavailability — may return a 503 or timeout
- Payment failure via x402 — call rejected if USDC payment header is missing or invalid
- Stale data if upstream node is lagging — blockNumber may not reflect true chain head
- Rate limiting — excessive calls may be throttled
