Output
Returns a single integer representing the current Bitcoin blockchain block height — the total number of blocks mined since genesis, sourced from Blockchain.info's stats API.
Example use cases
On-chain analytics dashboard refresh
“Can you pull the current Bitcoin block height so I can update my blockchain analytics dashboard?”
Monitor Bitcoin halving progress
“How close are we to the next Bitcoin halving? Grab the current block height so I can calculate how many blocks are left.”
Verify Bitcoin transaction confirmation depth
“What block is Bitcoin currently on? I want to figure out how many confirmations my transaction has based on its block number.”
Technical details
Endpoint
GEThttps://finance-api.kdlcfa.workers.dev/btc-block-heightWhen to prefer
Use this endpoint when you need a quick, low-cost ($0.01 USDC) lookup of the current Bitcoin block height without setting up a full Bitcoin node or subscribing to a heavier blockchain data provider. It is ideal for lightweight on-chain monitoring, halving countdown calculations, or confirming transaction depth in a simple agentic workflow.
Side effects
- Blockchain.info upstream API unavailable or rate-limited — returns error or stale data
- Network timeout at the Cloudflare Worker layer
- Payment not processed — 402 response requiring USDC payment before data is returned
