Abstract API pricing

Each API is priced and billed on its own, so you only pay for the ones you use. Every plan includes the full API response, including the free one, and annual billing saves 10%. Pick a plan below by the data you need, then set your volume in the dashboard.

How Abstract API pricing works

Abstract prices each API on its own meter, so email validation API pricing, phone validation API pricing and IP geolocation API pricing are separate lines on your bill and you only pay for the APIs you actually call. Every API has a permanently free tier with no credit card, and every plan returns the complete API response rather than a trimmed one.

Plans differ by the data each response carries, not by speed or support. Starter returns the core validation fields, Standard adds enrichment, and Professional adds the risk and reputation signals used for fraud scoring. Volume is a separate choice: you set requests per month inside your plan, and the cost per 1,000 requests falls as that volume rises. Annual billing is 10% cheaper than paying monthly for the same plan.

Rate limits are separate again. They cap requests per second rather than requests per month, so a burst of traffic is governed by the rate limit while your monthly quota governs total usage.

Cost per 1,000 requests
Email validation$3.40
Phone validation$3.40
IP geolocation$0.085

At each API's entry volume on Starter, billed annually. Free tier: 100 requests a month on email and phone, 1,000 on IP.

Email Validation pricing FAQ

What is included in the free Email Validation plan?

100 requests a month, no credit card. The free plan returns the same full API response as the paid plans, so you can test the exact payload you will ship before you pay anything.

Starter is $17 a month billed annually and includes 5,000 requests a month, which works out to $3.40 per 1,000 requests. Cost per request falls as you raise the volume inside a plan.

What is the difference between Starter, Standard and Professional?

Phone Validation pricing FAQ

What is included in the free Phone Validation plan?

100 requests a month, no credit card, at 3 requests a second. The free plan returns every field the paid plans return, so you can check the response shape before committing.

Why do all three paid Phone plans cost the same?

They cost $17 a month billed annually and differ by volume rather than price. Starter includes 5,000 requests a month, Standard 3,000 and Professional 2,000, because each step adds more data to every response. You are trading volume for depth at a fixed price.

Which plan returns carrier and line type?

Starter. It returns validation, location and carrier, which covers carrier lookup and line type checks. Standard adds messaging details, and Professional adds registration and risk signals for fraud scoring.

Can I pay monthly instead?

Yes. Every paid Phone plan is $19 a month paid monthly, against $17 billed annually. The included volume is the same either way.

IP geolocation API pricing compared

The cheapest plan at each provider that covers 200,000 IP lookups a month. None of the three sells a plan at exactly that volume, so this is the plan you would actually have to buy. Abstract's price is billed annually, $19 paid monthly.

IP Geolocation pricing FAQ

What is included in the free IP Geolocation plan?

1,000 requests a month at 1 request a second, no credit card. The free plan returns the complete response, including the security and company fields that paid plans gate.

How much does IP geolocation cost per 1,000 requests?

Starter is $17 a month billed annually and includes 200,000 requests a month, which works out to $0.085 per 1,000 requests. IP lookups usually sit on every request rather than at signup, which is why the entry volume is far higher than the other two APIs.

What is the difference between the plans?

Starter returns ASN, location, timezone, flag and currency. Standard adds company information. Professional adds the security signals and domain data used for VPN, proxy and fraud detection.

What is the rate limit?

10 requests a second on every paid plan, and 1 request a second on the free plan. Rate limits are separate from volume: they cap how fast you can call, not how much you can call in a month.
