How this service works
Cross-verified: Live Bitcoin mempool congestion from mempool.space fee estimates. Combined with base address balance/activity/contract check.
Output
Returns a structured JSON object with an ok flag, service slug, score, summary, confidence rating, array of strengths, array of risk factors, evidence object with raw data, and a generatedAt ISO-8601 timestamp. The result combines live mempool fee tiers (slow/medium/fast sat/vbyte) with address-level balance and activity signals.
Example use cases
Set optimal Bitcoin transaction fee
“What's the current Bitcoin mempool congestion like and what fee rate in sat/vbyte should I use to get my transaction confirmed in the next 30 minutes?”
Vet a Bitcoin payment counterparty
“Before I send funds, can you check the Bitcoin address bc1qxy2kgdygjrsqtzq2n0yrf2493p83kkfjhx0wlh — is it active, does it have a balance, and does it show any risk factors?”
Monitor Bitcoin network before large payment
“I'm about to make a large Bitcoin payment — can you pull the live mempool fee estimates and give me a summary of current network congestion so I know the best time to send?”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/bitcoin-fee-pulse-address-fingerprint?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need both current Bitcoin mempool fee conditions and a quick fingerprint of a specific Bitcoin address in a single call, rather than making two separate API requests. It is ideal for agents that need to vet a payment counterparty while simultaneously checking whether network fees are reasonable before initiating a transaction.
Side effects
- Mempool.space API unavailable — fee data may be stale or missing
- Invalid or malformed Bitcoin address returns an error or empty address result
- Network timeout causes partial data return
- Address has no on-chain history, yielding low confidence scores
- Payment not completed results in 402 response requiring x402 payment
