## What the models said for it

- "Google Maps API / Address Validation API best for consumer-facing forms; limited access to underlying reference data." (Muse Glimmer 30B, Address verification)
- "5,000 free calls/month, then ~$5–$17 per 1,000 ... but it's more of a general geocoder than pure postal verification" (Grok 4.20, Address verification)
- "Convenient global option with particularly strong U.S. validation and easy alignment with other Google services" (Perplexity Sonar, Address verification)
- "If your volume is extremely low: Try Google's Address Validation API with the $300 free credit first" (Kimi K2, Address verification)

## And against it

- "Skip the "free" options like Google's Address Validation API" (DeepSeek V4 Flash, Address verification)
- "Google's Address Validation API terms say it may share customer name/address and related usage data with USPS in some cases" (GPT-5.4 mini, Address verification)
- "Caveat: It's not USPS-certified, so it's better for mapping/geocoding than guaranteeing mail deliverability." (Kimi K2, Address verification)
- "Not a postal-certified validation source; accuracy for actual mail deliverability is debated" (Kimi K2, Address verification)
