Technical details
Endpoint
POSThttps://api.blockchain.info/explorer-gateway-kt/x402/btc/address?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative, real-time Bitcoin or Bitcoin Cash address data sourced directly from the Blockchain.com Explorer — one of the most trusted and widely-used block explorers. Prefer it over generic blockchain APIs when you need reliable BTC/BCH address lookups with a per-call micropayment model rather than API key subscriptions.
Side effects
- Invalid or malformed address returns an error response
- Address not found on-chain (unused address) may return empty/zero balances
- Rate limiting if called too frequently
- Payment failure via x402 protocol if USDC balance is insufficient
- Network timeouts if blockchain node is congested
