How this service works
Bitcoin address validator - checks base58check and bech32/bech32m checksums, returns network, address type (P2PKH, P2SH, P2WPKH, taproot) and encoding
Output
Returns a JSON object with: address (the input), valid (boolean), network (e.g. mainnet/testnet), type (P2PKH, P2SH, P2WPKH, P2TR, etc.), encoding (base58check or bech32/bech32m), witness_version (for SegWit addresses), program_hex (the decoded witness program), checked_at (UTC timestamp), and reason (error description if invalid).
Example use cases
Pre-flight withdrawal address check
“Before I process this Bitcoin withdrawal, verify that 1A1zP1eP5QGefi2DMPTfTL5SLmv7Divf is a valid BTC address and let me know if it's mainnet or testnet and what address type it is.”
Taproot address format verification
“I just generated a new taproot address — bc1p5d7rjq7g6rdk2yhzks9smlaqtedr4dekq08ge8ztwac72sfr9rusxg3297 — can you confirm it passes the bech32m checksum and is correctly recognized as a taproot (P2TR) address?”
Detecting invalid or mistyped addresses
“A customer submitted this Bitcoin address for a refund: 1AGNa15ZQXAZUgFiqJ3i7Z2DPU2J6hW62i — can you run it through validation and tell me if there's any problem with the checksum or format?”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/tools/btc-address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call Bitcoin address validation that covers all modern address types (legacy P2PKH, P2SH, native SegWit P2WPKH, and taproot P2TR) and returns structured metadata including network and encoding — particularly useful in automated pipelines (e.g. wallets, exchanges, payment processors) that need to gate on address correctness before executing a transaction.
Side effects
- Missing required 'address' query parameter returns an error response
- Completely garbled non-address string returns valid=false with a reason explaining the failure
- Testnet addresses may be identified as testnet rather than invalid — callers should check network field
- Address with valid checksum but unsupported type may return unknown type field
- Network timeouts or service unavailability return HTTP 5xx errors
- Payment required (HTTP 402) if x402 payment is not provided or fails
