StatusUnknown

How this service works

Validate and standardize a postal address. Returns structured components, validity confidence, and suggested corrections. Works for 200+ countries via OpenStreetMap Nominatim.

Output

Returns a structured validation result indicating whether the address is valid, along with parsed components (street, city, postcode, country) where available, a confidence or status indicator, and a cryptographically chained audit record for provenance and compliance traceability.

Example use cases

E-commerce checkout address check

“Before we process this order, can you verify that '1600 Amphitheatre Parkway, Mountain View, CA 94043' is a real, valid address in the US?”

CRM data quality audit

“I have a customer record with address '45 Rue de Rivoli, 75001 Paris' — can you validate it and tell me if it's a legitimate French address?”

Fraud screening on sign-up

“A new user signed up with the address '999 Fake Boulevard, Berlin, 10115' and country code DE — can you validate whether that address actually exists?”

Endpoint

GEThttps://api.strale.io/x402/v2/address-validate

When to prefer

Choose this endpoint when you need address validation with a built-in cryptographic audit trail — particularly useful in regulated, compliance-sensitive, or multi-party workflows where you need to prove what data was checked and when. It supports 27 countries and accepts free-text input, making it suitable for unstructured address data from forms or user input. Prefer it over generic geocoding APIs when validation (is this address real?) rather than coordinate lookup is the goal.

Side effects

Missing required 'address' query parameter returns a 400 error
Unrecognized or unsupported country code may reduce match accuracy or return an error
Ambiguous or extremely abbreviated addresses may return low-confidence or unresolved results
Payment failure or insufficient USDC balance results in a 402 Payment Required response
Network timeouts or upstream address database unavailability return 503
Addresses in countries outside the 27 supported may return unsupported-region errors
