How this service works
Live Bitcoin fee estimates (sat/vB) + mempool size — on-chain congestion signal. Live. Returns JSON.
Output
A JSON object containing live Bitcoin fee estimates expressed in satoshis per virtual byte (sat/vB) across priority tiers (e.g. fast, medium, slow) and the current mempool size, enabling on-chain congestion assessment.
Example use cases
Example prompt
“What's the current Bitcoin fee rate in sat/vB and how congested is the mempool right now? I want to know if it's a good time to send a transaction.”
Technical details
Endpoint
POSThttps://clonecho.builda.company/x402/btc-networkWhen to prefer
Use this endpoint when you need a real-time, low-cost snapshot of Bitcoin network fees and mempool congestion, especially before broadcasting a transaction or building a fee-estimation feature. Prefer this over blockchain explorer APIs when you want a single JSON call with both fee rates and mempool size together at a fixed $0.01 USDC cost.
Side effects
- Upstream Bitcoin node or mempool data source unavailable — may return 5xx or stale data
- Payment not processed (402 Payment Required) if x402 header is missing or insufficient
- Rate limiting if called too frequently without valid payment
