How this service works
One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.
Output
Returns a JSON object with a boolean 'valid' field, a 'formatted' string of the corrected address, a 'components' object with parsed fields (street, city, state, zip, etc.), a 'confidence' score from 0 to 1, and an 'issues' array listing any detected problems such as missing components or formatting errors.
Example use cases
Validate customer shipping address
“Before I generate the shipping label, check if '1600 Pennsylvania Ave NW, Washington, DC 20500' is a valid address and flag any problems.”
Normalize freeform address input
“A user typed '55 water st new york ny' into our form — can you validate it, fix the formatting, and break it down into street, city, state, and zip?”
Verify billing address before payment
“The customer entered '9 W 57th St, New York NY 10019' as their billing address — is it valid and does it have a high confidence score?”
Technical details
Endpoint
GEThttps://klymax402.com/api/address-validator/api/validateWhen to prefer
Choose this endpoint when you need a quick, low-cost address parse-and-validate in a single call without managing API keys. It is ideal for agents that need structured address components plus a confidence score and issue list in one response, especially in workflows involving shipping, payments, or form validation.
Side effects
- Empty or null address string returns an error or low-confidence result
- Completely garbled input may return valid=false with issues but no structured components
- Ambiguous addresses (e.g. missing zip code) may return partial components and reduced confidence
- Non-US addresses may not be parsed correctly if the service is US-focused
- Payment failure (402) if USDC balance is insufficient
