Technical details
Endpoint
POSThttps://api.blockchain.com/explorer-gateway-kt/x402/btc/address?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need programmatic, pay-per-call access to Bitcoin or Bitcoin Cash address data without API key registration. Ideal for agents that need to verify payments, audit wallets, or enrich transaction data on demand. Prefer over free public explorers when you need reliable uptime backed by blockchain.com infrastructure and x402 micropayment billing.
Side effects
- Invalid or malformed address string returns an error response
- Address not found on-chain (e.g. never used) may return empty or zero-balance result
- Network timeout or upstream blockchain.com service unavailability
- Unsupported address format (e.g. non-BTC/BCH address submitted) returns an error
- Payment failure via x402 protocol results in 402 response and no data returned
