How this service works
L402-gated APIs: real-time Bitcoin mempool intelligence and private AI inference. Pay-per-call via Lightning. Zero API keys. Zero subscriptions.
Output
A JSON response containing current recommended Bitcoin transaction fee rates, likely including sat/vbyte values for different priority levels (e.g. low, medium, high / next-block), reflecting live mempool conditions at time of request.
Example use cases
Dynamic fee for wallet transaction
“I'm about to send Bitcoin from my wallet — what fee rate should I set right now to get confirmed in the next block?”
Mempool monitoring for trading bot
“Check the current Bitcoin mempool fee conditions and tell me if fees are low, medium, or high right now so I can decide whether to batch my transactions.”
Fee estimation for exchange withdrawal
“What's the recommended sat/vbyte fee rate for a Bitcoin withdrawal that should confirm within 30 minutes given the current mempool state?”
