How this service works
Pay-per-call APIs, paid downloads and work-on-request for agents. Payment: x402 (USDC on Base, eip155:8453), no accounts or API keys. Catalog: https://206-81-14-131.sslip.io/?format=json. Agent guide: https://206-81-14-131.sslip.io/llms.txt
Output
Returns whether the provided Bitcoin address is valid, including information about the address format (e.g. legacy P2PKH, P2SH, or bech32/SegWit) and any detected errors in the checksum or structure.
Example use cases
Pre-transaction address sanity check
“Before I send 0.05 BTC, can you check whether this address is a valid Bitcoin address: bc1qar0srrr7xfkvy5l643lydnw9re59gtzzwf5mdq?”
User-submitted wallet validation
“A customer entered this Bitcoin address on our checkout page — can you tell me if it's a valid BTC address or if they made a typo: 3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy?”
Bulk payment list pre-screening
“I've got this Bitcoin address from my vendor's invoice: 1BvBMSEYstWetqTFn5Au4m4GFg7xJaNVN2 — please verify it's a properly formatted Bitcoin address before I approve the payment.”
Technical details
Endpoint
GEThttps://206-81-14-131.sslip.io/svc/bitcoin-address/validate?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, pay-per-call Bitcoin address validation with no account setup or API key required. Ideal for agents that need on-demand validation in automated workflows, especially when using x402 micropayment infrastructure on Base. Prefer this over rolling your own checksum logic or using a full blockchain node query when all you need is format/validity confirmation.
Side effects
- Missing or empty address parameter returns an error
- Malformed address string returns invalid status with reason
- Address from a different network (e.g. testnet) may be flagged as invalid or differently categorized
- Network errors or timeouts from the upstream service
- Payment failure via x402 protocol if USDC balance is insufficient
