Technical details
Endpoint
POSThttps://twin.unykorn.org/btc-tip?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call lookup of the current Bitcoin block height without managing a full Bitcoin node or subscribing to a data plan. It is ideal for agents that need occasional on-demand BTC chain tip checks and can pay micro-amounts per query via the x402 protocol.
Side effects
- Payment failure via x402 protocol if USDC balance is insufficient
- Network or upstream Bitcoin node unavailability causing stale or missing block data
- Malformed request body causing rejection
- Rate limiting or operator downtime on the UnyKorn network
