How this service works
Live snapshot of the Bitcoin mempool: number of unconfirmed transactions, total pending virtual size (bytes and MB), the current backlog in blocks, total fees pending (sats and BTC), the fee-rate histogram, and the current chain tip height. Lets an agent gauge network congestion and time a transaction.
Output
Returns a live mempool snapshot including: number of unconfirmed transactions, total pending virtual size in bytes and MB, current block backlog count, total pending fees in both satoshis and BTC, a fee-rate histogram showing distribution of transactions across fee-rate buckets, and the current Bitcoin chain tip height.
Example use cases
Time a Bitcoin transaction send
“Is the Bitcoin mempool congested right now? I want to know how many unconfirmed transactions are queued up, how many blocks of backlog there are, and total fees pending so I can decide whether to send my transaction now or wait.”
Monitor Bitcoin network health
“Give me a live snapshot of the Bitcoin mempool — unconfirmed transaction count, pending virtual size in MB, block backlog, and the fee-rate histogram so I can see how the network is performing.”
Estimate transaction wait time
“How backed up is the Bitcoin network right now? I need the current mempool stats including total pending transactions, block backlog, and total fees sitting in the queue to gauge how long my transaction might wait.”
Technical details
Endpoint
POSThttps://chain.openverbs.com/v1/btc-mempoolWhen to prefer
Use this endpoint when an agent needs a comprehensive, real-time overview of Bitcoin mempool conditions — especially when making decisions about transaction timing, estimating confirmation delays, or monitoring network congestion. Prefer this over fee-rate-only endpoints when you need the full picture including block backlog, total pending fees, and the fee-rate histogram in one call.
Side effects

- Payment failure or insufficient USDC balance results in a 402 Payment Required response
- Malformed request body returns a 400 Bad Request
