NAME
match-key-address — generates a match key for postal addresses with usps-style standardization so equivalent addresses collide
SYNOPSIS
POST https://x402.agentutility.ai/match-key-address
Content-Type: application/json
X-PAYMENT: <signed-transferWithAuthorization>
{ ... }↳ first call →
402 Payment Required. Sign USDCtransferWithAuthorization, retry with theX-PAYMENT header.DESCRIPTION
Generates a match key for postal addresses with USPS-style standardization so equivalent addresses collide. Expands street types (St to Street), directionals (N to North), and unit designators (Apt/Ste/# to unit), then builds a stable key so '123 Main St Apt 4' and '123 Main Street #4' collide. Deterministic and instant — no geocoding or external lookups. Use it for postal address dedup and address record linkage.
