How this service works
22 agent-native micro APIs paid per call in USDC on Base via x402: funded bounty radar, honeypot trust scoring, token safety verdicts, crypto prices, multi-asset price snapshots, fear & greed index, full market-pulse snapshot, AI chat completion (Llama 3.1), crypto news, weather, web reader, ERC-20 balances. No accounts, no API keys — instant on-chain settlement.
Output
A JSON object containing: the estimated halving date (eta), the Bitcoin network name, days remaining (daysLeft), current block height (btcHeight), blocks remaining until halving (blocksLeft), post-halving block reward string (rewardAfter), halving sequence number (halvingNumber), and the target block height for the next halving (nextHalvingHeight).
Example use cases

Mining economics planning
“What will the Bitcoin block reward be after the next halving, and when is that halving expected to occur?”

Endpoint
GEThttps://mr-river8.makar52nn2016.workers.dev/api/btc-halving?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single structured snapshot of Bitcoin halving metrics — date estimate, days remaining, block heights, and reward schedule — paid per call with no API key or account setup, especially in automated agent workflows that need current halving data on demand via x402 micropayments on Base.
Side effects
- Payment not included or insufficient USDC — returns 402 Payment Required
- Upstream block height data unavailable — may return stale or error response
- Network congestion on Base causing delayed x402 settlement — request may time out
- Invalid or missing x402 payment header — request rejected before processing
