How this service works
Bitcoin mempool state (free/keyless): current unconfirmed tx count, total vsize, and total fees, plus the most recent transactions (whale radar) — filter with minBtc to surface only large pending transfers. For congestion monitoring and large-transfer alerts.
Output
Returns current Bitcoin mempool statistics including total unconfirmed transaction count, aggregate vsize, and total pending fees, along with a list of recent mempool transactions optionally filtered to only those above a specified BTC threshold (whale radar).
Example use cases
Example prompt
“What's the current state of the Bitcoin mempool — how many unconfirmed transactions are there, what are the total fees, and can you show me any pending transfers worth at least 5 BTC?”
Technical details
Endpoint
GEThttps://2s.io/api/crypto/btc-mempoolWhen to prefer
Use this endpoint when you need real-time Bitcoin mempool data without an API key — ideal for congestion monitoring dashboards, fee estimation context, or whale-watching alerts. Prefer this over on-chain confirmed transaction APIs when you specifically need pending/unconfirmed transaction data.
Side effects
- Network or upstream Bitcoin node unavailability returning 5xx errors
- Invalid minBtc value (negative number) returning a validation error
- Mempool data temporarily stale if node sync is delayed
- Empty recent transactions array if no transactions meet the minBtc threshold
