How this service works
Validate and standardize a delivery address: parsing, provider verification (US-optimized), geocoding and a deliverability score, as JSON. 0.02 USDC per call on Base. Useful before shipping to or storing an address.
Output
A JSON object containing the standardized address fields (street, city, state, ZIP), geocoordinates (latitude/longitude), a deliverability score indicating how likely the address can receive mail or packages, and any corrections or parsing notes applied during validation.
Example use cases
Pre-shipment address check
“Before I ship this order, can you validate the customer's address — 456 Oak Avenue, Austin, TX 73301 — and tell me whether it's deliverable and give me the standardized version?”
Database address cleanup
“I'm about to save this address to our customer database: 789 Elm St, Brooklyn, NY 11201 — can you validate and standardize it first so we store a clean, verified version?”
E-commerce checkout verification
“A customer just entered '22 West 34th Stret, New York, NY 10001' at checkout — can you validate and correct that address and give me a deliverability score before we accept the order?”
Technical details
Endpoint
POSThttps://kder-ai.com/validate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need combined address parsing, USPS-style carrier deliverability scoring, and geocoding in a single call for US addresses — particularly before storing an address in a database or initiating a shipment. It is well-suited for e-commerce checkout flows, CRM data cleansing, and logistics pre-validation where a deliverability confidence score matters alongside coordinate lookup.
Side effects
- Address not found in provider database — returns low or zero deliverability score
- Invalid or missing required fields (street, city, state, ZIP) — returns 400-level error
- Non-US addresses may have reduced accuracy since service is US-optimized
- Ambiguous address with multiple possible matches — may return lowest-confidence result or require disambiguation
- Payment failure (insufficient USDC balance) — request rejected before processing
