How this service works
Bitcoin blockchain data, address portfolio, transaction tracing, fee forecasting, whale monitoring, SEC EDGAR filings, URL scraping, AI summarization, and Reddit API via x402 micropayments on Base.
Output
Returns current Bitcoin fee rates in sat/vB, predictions for the next 3 blocks, and a trend analysis indicating whether fees are rising, falling, or stable — sourced from a live Bitcoin Core node.
Example use cases
Optimize wallet sweep timing
“I need to move some Bitcoin around. Tell me what fees are looking like right now and whether I should wait a bit for them to drop, or if they're stable enough to go ahead with the transfer.”
Batch transaction scheduling
“I'm planning to send Bitcoin to several addresses today. What's the fee situation looking like over the next few blocks? Should I batch everything together now or split it up and send in waves?”
DCA trade execution strategy
“I'm doing a dollar-cost average Bitcoin buy this week. Given current fees and where you think they're headed, what's the best time window for me to execute my purchases without overpaying on chain costs?”
Technical details
Endpoint
GEThttps://btcnode.uk/api/fees/predictWhen to prefer
Choose this endpoint when you need not just current fee estimates but also forward-looking block-level predictions and trend direction — ideal for timing Bitcoin transactions optimally. Prefer over basic fee estimators when the agent needs to decide whether to send now or wait.
Side effects
- Node unavailable: Bitcoin Core node may be temporarily unreachable, returning a 5xx error
- Stale data: if node is syncing, fee data may be slightly outdated
- No mempool activity: very low congestion periods may yield minimal forecast variance
- Payment failure: x402 micropayment of $0.001 USDC not processed correctly
