Address validation: flat rate vs per-lookup
Most address validation APIs charge per lookup. RevAddress charges a flat monthly fee — after that, every lookup is $0. At 4,300+ lookups/month, RevAddress is cheaper than every per-lookup competitor.
| Provider | 1K lookups | 10K lookups | 50K lookups | Batch? |
|---|---|---|---|---|
| Smarty | $40 | $400 | $2,000 | Per-lookup |
| Melissa | $30 | $30 | $150 | Per-credit |
| Google AV | $5 | $50 | $250 | Per-call |
| Lob | ~$20 | ~$200 | ~$1,000 | Per-lookup |
| RevAddress | $29 | $29 | $79 | 50/call |
RevAddress Starter ($29/mo) includes 5,000 lookups. Growth ($79/mo) adds batch validation — 50 addresses per call. Cached addresses are free. Learn about batch validation →
Shipping API: per-lookup fees vs flat rate
Most shipping APIs charge per lookup or per label. RevAddress is flat — tracking, intelligence, checkout validation, and BYOK included in your plan. Pro and Enterprise merchants create labels through their own USPS credentials.
| Platform | Monthly | Per lookup | 1K lookups/mo | BYOK |
|---|---|---|---|---|
| EasyPost | $0 | $0.08 | $80 | No |
| Shippo | $19 | $0.05 | $69 | No |
| USPS native | $0 | $0 | $0 | N/A |
| RevAddress | $79 | $0 | $79 | Pro+ |
USPS native is free but requires your own OAuth management, token refresh, and error handling. RevAddress handles USPS infrastructure — OAuth, caching, webhooks, SDKs — so you build, not plumb. Full comparison →
Common questions
What counts as a request?
Every API call to any endpoint counts as one request. Address validation, tracking lookups, intelligence queries — each is one request. Cached responses don't count.
What happens if I exceed my limit?
Requests over your plan limit return a 429 status code. No surprise charges. Upgrade from your dashboard or start a new checkout from pricing. Email [email protected] if you need help.
What is BYOK?
Bring Your Own Keys. Use your own USPS Developer Portal credentials with our infrastructure. Your credentials are AES-GCM encrypted at rest with per-merchant keys. If your USPS app has label creation access, you can create shipping labels through RevAddress using your own credentials and payment authorization — we manage the token lifecycle, rate limits, and storage. Available on Pro and Enterprise plans.
Can I try the API for free?
Yes. Get a free API key to validate addresses, extract addresses from unstructured text, resolve ZIP+4, and compare rates. Upgrade when you need tracking, intelligence, batch validation, or BYOK.
How does this compare to EasyPost?
Our Growth plan at $79/mo includes 25,000 requests with batch validation, address intelligence, and Checkout Guard — no per-lookup surcharges.
Can I cancel anytime?
Yes. No contracts, no cancellation fees. Cancel from your dashboard or email [email protected]. Your API key stays active until the end of the billing period.
Monthly vs annual billing?
Annual plans save 20% — pay for 10 months, get 12. Same features, same limits. Choose monthly or annual at checkout. Existing customers can switch from their dashboard or by emailing [email protected].
