- On these published prices SimpleVerifier costs less at every volume Abstract API's page prices (1,000, 10,000, 50,000, 100,000 a month).
- SimpleVerifier one-time packs ($9 for 2,500 emails or $19 for 10,000 emails) never expire but cover email verification only, without the API, finder or phone lookups. Pro includes them.
- Pro has no monthly cap, but runs at up to 45 checks a minute per account, so 100,000 addresses take about 37 hours. Larger lists queue rather than fail.
- “Not published” means Abstract API’s page did not price that volume; we do not extrapolate. Run your own numbers in the cost calculator.

How Abstract API meters usage
In Abstract API’s own framing: monthly request allowance. What to watch: the plan is a request quota, so a bulk clean and your live sign-up checks compete for the same allowance.
What it does well: Abstract API is worth keeping if you already use Abstract's other APIs, such as IP geolocation or phone validation, and want one key and one bill.
For small volumes Abstract API can cost less than Pro: up to 5,000 addresses can be bought from Abstract API for under $29.99. If that covers your list and you verify it once, Abstract API may be the better buy.
How to work out what Abstract API will cost you
- 1
Count how many addresses you verify in a typical month, including re-checks of lists you already cleaned.
- 2
Find the smallest Abstract API tier whose allowance covers that number in the plans table, and compare it with buying a pay-as-you-go pack of that size, if Abstract API sells one.
- 3
Check whether unused Abstract API credits expire before you would use them, and whether the plan meters finding and verifying from the same pool.
- 4
Compare the result with SimpleVerifier: one-time packs at $9 for 2,500 emails or $19 for 10,000 emails, or Pro at $29.99 a month with no monthly cap and a throughput of 45 checks a minute per account.
