EasyPost vs Loqate: API comparison

The short answer

Loqate Verify is a stronger conceptual fit for a standalone international cleansing pipeline; EasyPost fits verification within shipping operations. Confirm actual country coverage and international AVS enablement before treating both as equivalent global services.

Choose by the task you need to complete
Provider	A good reason to choose it	Important caveat
EasyPost	A shipping workflow already using EasyPost that needs verification results before proceeding to shipment and label operations.	Creating an Address object is not a passed verification. Including verify or verify_strict triggers verification even with false; omit the parameter to skip it. International AVS requires separate enablement.
Loqate	A multinational address-data pipeline that needs country-aware cleansing, multiple input records and explicit quality codes.	Capture suggestions are not Verify results. Pin the endpoint version and interpret Address Verification Codes in the relevant country context instead of comparing them numerically with another provider's confidence score.

Side-by-side differences

EasyPost vs Loqate: documented interfaces, not benchmark scores
Requirement	EasyPost	Loqate
Validation approach	Verification associated with shipping Address objects	Country-aware Address Verify cleansing
Coverage boundary	Domestic checks; international AVS is separately enabled	International country coverage and data depth vary
Decision signal	verifications success/errors, not Address creation alone	AVC and match/quality details need interpretation
Apartment/unit handling	Preserve street2 and inspect correction/splitting behavior	Country-specific sub-building and address components
Workflow	Create-and-verify or verify an existing Address object	Single or batch input through International Batch Cleanse
Cost driver	Account/service entitlement and verification workload	Input addresses, service credit rules and optional enrichment

Pricing: make the units comparable

Billing model and plan checks
Provider	Billing model	What to check
EasyPost	Shipping-account and address-service pricing	Confirm standalone address verification, international AVS and carrier-grade access on your account. Free label allowances or tracking prices are not standalone validation prices.
Loqate	Service-specific credits and account pricing	Confirm the Address Verify entitlement, per-address consumption and optional geocoding. An address-capture lookup price is not automatically the price of a batch cleansing record.

For 10,000 address checks, include retries and customer edits, not just completed orders. Count input addresses rather than batch HTTP calls. Compare the same country mix and postal evidence; a geocoding credit and a delivery-verification check do not buy the same result.

For a buying decision, calculate total spend divided by accepted outputs at your expected volume. Keep free evaluation access, paid production access, annual commitments and overages separate. We have not measured a cost or speed winner for this pair.

What changes in the integration?

Provider endpoints and input mapping
	EasyPost	Loqate
Method and URL	`POST https://api.easypost.com/v2/addresses`	`POST https://api.addressy.com/Cleansing/International/Batch/v1.20/json6.ws`
Authentication	HTTP Basic auth with the API key as username and an empty password	Loqate Key scoped to the selected service
Inputs	JSON address with street1/street2, city, state, zip and country; include verify or verify_strict deliberately	JSON Key, Addresses array with country/address components; optional GeoCode and processing options
Output	Address object plus verifications with success, errors and details; strict verification fails when verification fails.	Per-input match records and normalized fields with quality information such as AVC; optional geocoding output.

EasyPost: migration check

Omit verify fields entirely when verification is not wanted; false is not an off switch. Distinguish strict API errors from non-strict verification errors before deciding whether a parcel may proceed.

Loqate: migration check

Pin v1.20/json6 or your contracted version and map quality codes using official definitions. Keep Capture's Find/Retrieve workflow out of a Verify adapter and preserve per-record identifiers in a batch.

How to test them fairly

Use provider-approved test fixtures or addresses you have permission to process. Include international formats, accents, rural addresses and unit numbers. Do not generate arbitrary postal addresses or send private customer records without authorization.
Define expected outcomes for known-good records and approved negative cases before the run. Keep unsupported countries and missing evidence separate from invalid addresses.
Measure component correction, unit preservation and false rejection separately. A geocoder's building-level match is not confirmation of postal deliverability or of the person living there.
Record whether the API suggests a correction, confirms a delivery point or merely finds a location. Require customer confirmation when a suggested change could route a parcel elsewhere.
Count billed address checks, repeated checkout attempts, optional geocoding and batch records. Compare latency and cost per accepted decision on the same country mix. No validation result guarantees a successful future delivery.

Record the plan, request settings, time window and acceptance rules with every run. That makes a later result interpretable when a vendor changes a model, source set or pricing tier.
