ZeroBounce is a direct verification option. TaskFuel provides the tested Hunter verifier and a separate syntax/DNS check. Their status fields have different meanings.

Try it in your next task.

Connect your agent to TaskFuel and ask it to show the status and evidence behind an address check.

01

Name the task

Tell your agent what the output needs to contain.

02

See the price

Your agent shows the provider and price before spending.

03

Review the response

Check the output against your task. The call reports its cost and remaining balance.

When to use it.

Before a reviewed send

Inspect the verification verdict.

Your agent reads Hunter’s status and confidence score before a separate sending step.

Basic input hygiene

Read syntax and mail records.

Your agent uses the lighter check for syntax and DNS signals when a mailbox verdict is not required.

Handling disagreement

Keep the signals separate.

Your agent reports the different flags returned by the two providers, as in our reserved-domain test.

Good Questions.

Do I need a Hunter or 2s account?

No. Your agent pays from your TaskFuel balance, so there is nothing else to sign up for.

What did the checks cost?

Hunter cost $0.008 and 2s cost $0.0025 on 5 November 2026. Your agent shows the price for your own request before it pays.

Does ZeroBounce require a subscription?

No. ZeroBounce offers prepaid credits as well as subscriptions. Its published minimum top-up is $39 for 2,000 credits, and a free account includes 100 monthly credits.

Are these equivalent verification services?

Hunter returns a verification verdict. The 2s operation reports syntax, heuristics and mail-record presence. It does not establish mailbox existence.

Why did the disposable flags differ?

The providers returned different labels for the same reserved domain. We report those labels separately; this one synthetic input does not establish which provider is more accurate.

Can a valid status guarantee delivery?

Delivery also depends on the receiving system and the message. These requests returned verification signals and sent no message.
