How this service works
Validate a Bitcoin address checksum offline: base58check or bech32/bech32m, with type and network (mainnet or test).
Output
Returns a structured object containing: verdict (valid/invalid), address type (P2PKH, P2SH, P2WPKH, P2WSH, P2TR, etc.), network (mainnet or testnet), witness version (for SegWit addresses), a human-readable summary, reasons for any failure, a list of unchecked properties, a degraded flag, and an asOf timestamp. All validation is performed offline without blockchain queries.
Example use cases
Validate user-submitted withdrawal address
“Before I process this Bitcoin withdrawal, check if 1A1zP1eP5QGefi2DMPTfTL5SLmv7Divf is a valid address and what type it is — I don't want to send funds to a malformed address.”
Distinguish mainnet vs testnet address
“Is tb1qw508d6qejxtdg4y5r3zarvary0c5xw7kxpjzsx a testnet Bitcoin address or a mainnet one? I need to make sure I'm not mixing up environments.”
Identify address encoding format
“Can you tell me whether 3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy uses base58check or bech32 encoding, and confirm it passes the checksum?”
Technical details
Endpoint
GEThttps://bitcoin-network.x402tookit.com/btc-address-validate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, offline format and checksum validation of a Bitcoin address before sending funds or storing the address — it does not hit the blockchain, so it is ideal for pre-flight checks in payment flows, user input validation, and address sanitization pipelines. Use the sibling balance-checking endpoint if you also need on-chain balance and transaction history.
Side effects
- Invalid or malformed address returns a failed verdict with reasons explaining the checksum or format error
- Missing required 'address' query parameter returns a 400-level error
- An address with a valid checksum but unknown or ambiguous prefix may return partial type information
- Network connectivity issues to the API itself (though validation is offline, the HTTP call may fail)
