How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object with a boolean 'valid' field indicating whether the input conforms to the Bitcoin Base58 alphabet, the integer 'length' of the string, the 'alphabet' type used (bitcoin-base58), and a 'schema' identifier. Does not return decoded values.
Example use cases
Validate Bitcoin address before payment
“Before I broadcast this transaction, can you confirm that '3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy' is a valid Base58 string using the Bitcoin alphabet?”
Check encoded key in wallet integration
“I'm building a wallet and need to verify that the public key 'xpub661MyMwAqRbcFW31YEwpkMuc5THy2PSt5bDMsktWQcFF8syAmRUapSCGu8ED9W6oDMSgv6Zz8idoc4a6mr8BDzTJY47LJhkJ8UB7WEGuduB' passes Base58 validation — can you check it?”
Sanitize user-submitted blockchain address
“A user submitted the address '0xInvalidAddr' as a Bitcoin address — can you run it through Base58 validation to see if it's actually well-formed?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/base58-validate?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, cheap, pay-per-call Base58 format check with no signup overhead — ideal for agents validating Bitcoin-style addresses or encoded keys before passing them to downstream blockchain APIs. Prefer this over rolling your own regex when you want a verifiable, schema-stamped result.
Side effects
- Missing or empty 'value' field returns a validation error
- Non-string input may cause a bad request response
- Payment failure via x402 protocol will block the call before processing
- Network or service unavailability returns a 5xx error
