How this service works
Interactive Bitcoin 4-year halving cycle chart on a polar disc. Live price, 200W MA, Mayer Multiple, RSI, MACD, Pi Cycle and optional paid cycle projections.
Output
A JSON object containing: live BTC fee estimates (fastest, halfHour, hour, economy, minimum in sat/vB); mempool stats (transaction count, vsize in bytes, total fees in satoshis); blockchain state (current block height, next halving height, blocks remaining, estimated seconds to halving); and difficulty epoch data (progress percent, remaining blocks, next retarget height, difficulty change percent, estimated retarget date timestamp). Additional indicator fields (200W MA, Mayer Multiple, RSI, MACD, Pi Cycle) are implied by the description and may appear in the full paid response.
Example use cases
Pre-halving investment timing check
“How far are we from the next Bitcoin halving, and where does the Mayer Multiple and Pi Cycle indicator put us in the 4-year cycle right now?”
Mempool congestion monitoring
“What are the current Bitcoin mempool size and recommended fee rates — I need to know if it's a good time to send a transaction or if I should wait.”
Cycle top/bottom signal scanning
“Check the current Bitcoin RSI, MACD, and 200-week moving average against the live price — I want to see if any of the classic cycle indicators are flashing a top or bottom signal.”
Technical details
Endpoint
GEThttps://4yearcycle.com/x402/btcWhen to prefer
Choose this endpoint when you need a single API call that consolidates Bitcoin on-chain cycle metrics (Mayer Multiple, Pi Cycle, 200W MA, RSI, MACD) together with real-time mempool data and halving countdown into one JSON response, particularly when analysing Bitcoin's 4-year cycle position for timing investment decisions. Prefer it over generic Bitcoin price APIs when the cycle-phase indicators matter, and over block-explorer APIs when you also need fee rate and mempool congestion data in the same call.
Side effects
- Payment not included or invalid — HTTP 402 returned, no data delivered
- Rate limit exceeded — too many calls within the billing window
- Upstream Bitcoin node or data provider temporarily unavailable — partial or stale data returned
- Malformed response if the chain is mid-reorg — block height may be inconsistent
- Pi Cycle and advanced indicator fields may be absent if the paid projection tier is not unlocked
