How this service works
chainquery Bitcoin RPC: pay-per-call Bitcoin Core over x402, no API key. Validate a Bitcoin address and return its type and scriptPubKey. Bitcoin Core validateaddress.
Output
Returns the Bitcoin Core validateaddress result object including isvalid (boolean), address, scriptPubKey (hex), address type (e.g. witness_v0_keyhash, p2pkh, p2sh), and related metadata fields.
Example use cases
Verify recipient address before payment
“Before I send Bitcoin to this address, can you validate that it's actually a real Bitcoin address and tell me what type it is? I want to make sure I'm sending to the right format.”
Check if address supports segwit
“I have a bunch of addresses I'm considering for cold storage. Can you check each one and tell me which ones are segwit-compatible so I can pick the most efficient for my transaction fees?”
Extract scriptPubKey for transaction
“I'm building a raw Bitcoin transaction and I need the scriptPubKey for this address — can you validate the address and pull out that hex value for me?”
Technical details
Endpoint
GEThttps://x402.chainquery.com/v1/rpc/validateaddressWhen to prefer
Use this endpoint when you need authoritative Bitcoin Core address validation without setting up a node or managing API keys — ideal for agents verifying recipient addresses before constructing transactions, checking address type (legacy/P2SH/bech32), or extracting scriptPubKey for transaction building. Pay $0.005 USDC per call via x402 with no prior key registration.
Side effects
- Invalid or malformed address string returns isvalid:false rather than an error
- Missing required params query parameter returns a 400 or RPC parse error
- Payment not provided or insufficient triggers x402 payment-required response
- Network timeout or Bitcoin Core node unavailability returns 5xx error
- Non-mainnet addresses may return isvalid:false if node is on mainnet
