How this service works
Returns the live Bitcoin mempool backlog: pending transaction count, total vsize, aggregate fees and a full fee-rate histogram from mempool.space. Powers autonomous agents and agent-to-agent schedulers that time broadcasts around network congestion and estimate clearing time by fee band. First 3 calls FREE per wallet — send header X-WALLET: 0x<addr>. No charge on upstream failure.
Output
A JSON object containing: a boolean success flag, a niche identifier ('bitcoin-mempool-congestion'), and a result object with the live mempool state including pending transaction count, total vsize (in virtual bytes), aggregate fees waiting in the mempool, and a full fee-rate histogram showing transaction volume bucketed by sat/vbyte fee bands.
Example use cases
Time a low-fee Bitcoin broadcast
“Check the Bitcoin mempool right now and tell me if congestion is low enough that I can safely broadcast my transaction at 5 sat/vbyte and expect it to confirm within a few hours.”
Agent scheduler picks optimal broadcast window
“I need you to monitor the Bitcoin mempool and let me know when the low-priority fee band drops below 10 sat/vbyte so my scheduled payment goes out at the cheapest possible time.”
Dashboard showing live network fee pressure
“Pull the latest Bitcoin mempool snapshot — pending tx count, total vsize, fee histogram — so I can display current network congestion on my analytics dashboard.”
Technical details
Endpoint
POSThttps://bitcoin-mempool-congestion.hergertsynthora.com/serviceWhen to prefer
Choose this endpoint when you need a holistic real-time mempool snapshot — especially the fee-rate histogram — rather than just a simple fee recommendation. Ideal for autonomous agents or agent-to-agent schedulers that need to reason about congestion tiers, estimate clearing times by fee band, and decide when to broadcast transactions. Prefer this over simple fee estimators when you need the full distribution of pending transactions across fee buckets.
Side effects
- Upstream mempool.space API unavailable — returns error with empty result object
- Network timeout if mempool.space is slow to respond
- Invalid or missing authentication keys — returns unauthorized error
- Malformed request payload — returns validation error
- Stale data if mempool.space cache is behind real-time state
