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 payload containing historical snapshots of the Bitcoin mempool, likely including time-series data on fee rates (sat/vB), pending transaction counts, mempool size in bytes, and block backlog metrics across the requested time window.
Example use cases
Bitcoin fee timing research
“Show me the historical mempool fee rates from Bitcoin Benji over the last week — I want to know what times of day tend to have the lowest fees so I can time my transactions better.”
On-chain congestion trend report
“Pull the Bitcoin mempool history from Bitcoin Benji and summarize how network congestion has changed over the past month — I'm writing a report on Bitcoin scalability.”
Automated fee alert baseline
“Fetch the recent mempool history from Bitcoin Benji so I can establish a baseline of typical fee levels and set up alerts when fees spike significantly above average.”
Technical details
Endpoint
GEThttps://api.bitcoinbenji.com/mempool/historyWhen to prefer
Choose this endpoint when you need historical mempool data — fee rate trends, congestion history, or past transaction volume — for Bitcoin network analysis, fee optimization research, or on-chain data enrichment. It is uniquely suited for pay-per-call workflows via Lightning/L402 where you don't want to commit to a subscription. Prefer alternatives if you need real-time (live) mempool state rather than historical records, or if you need Ethereum/other chain data.
Side effects
- Payment not received or Lightning invoice expired — returns 402 Payment Required
- Invalid or expired L402 token — returns 401 Unauthorized
- Rate limit or token reuse — returns 403 Forbidden
- Service unavailable or mempool node sync issue — returns 503
- Malformed request parameters — returns 400 Bad Request
- Empty result set if time range has no recorded data
