How this service works
Recommended Bitcoin fee rates right now — Genesis402 / UnyKorn Operator Network
Output
A JSON response containing recommended Bitcoin fee rates (likely tiered by confirmation speed such as next block, ~30 min, and economy), along with a receipt object including a transaction hash, USD amount charged, and a receipt ID for auditing the pay-per-call charge.
Example use cases
Optimize Bitcoin transaction fee before sending
“Before I send this Bitcoin transaction, what fee rate should I set to get it confirmed in the next block without overpaying?”
Monitor mempool congestion for wallet app
“Pull the latest recommended Bitcoin fee rates so I can show my users the current low, medium, and high priority sat/vByte options in the wallet.”
Automate fee selection for batch payments
“What are the current Bitcoin fee rates? I need to pick the right sat/vByte for a batch of payments that need to confirm within a few hours.”
Technical details
Endpoint
POSThttps://twin.unykorn.org/btc-fees?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a real-time, pay-per-call Bitcoin fee rate lookup with x402 micropayment billing and an auditable receipt. It suits agents that need current sat/vByte recommendations on demand without maintaining a mempool node themselves. Prefer alternatives (free public mempool APIs) if cost per call matters more than the receipt/audit trail or x402 integration.
Side effects
- Bitcoin node or mempool data source temporarily unavailable — returns error or stale data
- Payment not processed correctly — 402 response if x402 payment header is missing or invalid
- Rate limiting or quota exceeded on the underlying fee data provider
- Network timeout if Bitcoin mempool query takes too long
