How this service works

Bitcoin mempool stats real-time. Unconfirmed tx count, total vsize MB, fee histogram, avg sat/vByte, current tip height, next difficulty adjustment estimate with progress %, remaining blocks, avg block time. AI agent BTC timing bot, mempool API, network congestion data.

Output

Returns a structured JSON object with: count of unconfirmed transactions, total mempool vsize in MB, fee histogram (distribution of transactions across fee rate buckets), average sats per vbyte, current tip block height, and next difficulty adjustment details including estimated percent progress, blocks remaining, and average block time.

Example use cases

Example prompt

“What are the current Bitcoin mempool stats — how many unconfirmed transactions are there, what's the average fee in sats per vbyte, and when is the next difficulty adjustment?”

Endpoint

POSThttps://proxy.suverse.io/v1/data/bitcoin-mempool-stats

When to prefer

Use this endpoint when an AI agent needs to make real-time decisions about Bitcoin transaction fee rates, assess network congestion before broadcasting a transaction, or track difficulty adjustment cycles. Prefer this over general blockchain explorers when you need a single structured response covering fee histograms, mempool size, and difficulty adjustment together in one call at low cost ($0.005 USDC).

Side effects

Upstream data source unavailable — returns 5xx error
Payment not provided or invalid — returns 402 Payment Required
Rate limit exceeded — returns 429 Too Many Requests
Temporary network latency causing stale or delayed mempool data
