How this service works
Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).
Output
Returns current Bitcoin mempool fee estimates broken down by priority tier (e.g. slow, medium, fast) expressed in satoshis per virtual byte (sat/vByte), reflecting real-time network conditions. Delivered as a JSON response after micropayment settlement in USDC on Base via x402.
Example use cases
Optimize BTC transaction fee before sending
“Before I send this Bitcoin transaction, what are the current mempool fee rates for slow, medium, and fast confirmation so I can pick the right one?”
Monitor mempool congestion for DeFi bot
“Check the current BTC mempool fees right now — I need the fast-confirmation sat/vByte rate to decide whether to execute my on-chain arbitrage trade.”
Alert when Bitcoin fees drop below threshold
“What are the Bitcoin mempool fees at this moment? I'm waiting for the fast fee to drop below 20 sat/vByte before I broadcast my transaction.”

Endpoint
GEThttps://acp-x402-scriptmasterlabs.onrender.com/x402/btc-mempool-fees?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time Bitcoin mempool fee estimates and are operating in a crypto-native, x402-compatible payment environment settling in USDC on Base. It is well-suited for AI agents that already handle x402 micropayments and need lightweight, pay-per-call access without a subscription. Prefer alternatives with richer documentation if exact schema fidelity is critical.
Side effects
- Payment not settled — 402 response if USDC payment via x402 is not included or insufficient
- Mempool data unavailable — upstream Bitcoin node or data provider outage returns an error or empty response
- Rate limiting — excessive calls may be throttled
- Malformed response — example schema is empty so exact field names are undocumented and may vary
- Cold start latency — hosted on Render free tier, may have slow initial response after inactivity
