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 object containing real-time Bitcoin mempool metrics such as pending transaction count, fee rate estimates across priority tiers (low/medium/high in sat/vbyte), mempool size in bytes, and network congestion indicators. Exact fields depend on the API's current schema version.
Example use cases
Optimal fee timing for Bitcoin send
“I want to send some Bitcoin — can you check the current mempool and tell me what fee rate I should use to get confirmed within the next couple of blocks without overpaying?”
Mempool congestion alert for trading bot
“Check the Bitcoin mempool right now and let me know if it's heavily congested — I need to decide whether to proceed with an on-chain settlement or hold off.”
Real-time fee dashboard for wallet app
“Pull the latest mempool stats for me — I want to see the current low, medium, and high priority fee rates so I can display them to my users.”
Technical details
Endpoint
GEThttps://api.bitcoinbenji.com/mempoolWhen to prefer
Choose this endpoint when you need real-time, pay-per-call Bitcoin mempool data without committing to a subscription or API key. Ideal for agents that occasionally need fee intelligence, wallet applications surfacing fee recommendations, or automated bots that need to make on-chain transaction decisions dynamically. Prefer this over free public mempool explorers when you want a programmatic, machine-readable JSON response with a reliable SLA and micropayment-gated access.
