What is the Verification Kit?
The Verification Kit is a set of real-world checks your product can run before it trusts an input, from bank details and company registrations to contact details and sanctions lists.
It reduces fraud, failed payments and compliance risk, and it lets you give AI agents more responsibility because their actions are checked against reality.
How AI products use it
- Check a supplier's bank details before an agent schedules a payment.
- Validate a customer's tax ID and company during onboarding.
- Confirm that emails and phone numbers are real at sign-up.
Why not build it in-house?
Each capability in the Verification Kit looks simple to build. The hard part is keeping it accurate, available and up to date once your product depends on it.
- Bank and IBAN checksBank directories and IBAN formats change constantly. Stale reference data means valid payments get rejected and invalid ones get through.
- Tax ID and company lookupsEvery country runs its own tax and company registry, with different access rules, formats and downtime.
- Sanctions screeningSanctions and AML lists update frequently. Screening against an outdated list is a compliance breach, and fuzzy name matching is hard to get right.
- Email and phone validationDeliverability, disposable domains and carrier data shift daily. Checks built on static rules lose accuracy fast.
Do you run an API that belongs in the Verification Kit?
Publish it on ApyHub and put it in front of the teams and AI agents building with the Verification Kit. Your API joins the catalog under one subscription, becomes callable through MCP, and earns from every call.
Questions about the Verification Kit
What is the ApyHub Verification Kit?
The Verification Kit is a set of real-world checks your product can run before it trusts an input, from bank details and company registrations to contact details and sanctions lists.
What is a KYB API?
A KYB (know your business) API verifies that a company exists and returns its registered details, using identifiers such as LEI, VAT number, name and country. It is used in onboarding and supplier checks.
What does IBAN validation check?
IBAN validation confirms that a bank account number is correctly formed and, with Advanced IBAN Validation, checks the bank details behind it before you send or request a payment.
What is sanctions screening?
Sanctions screening checks a person or company name against sanctions and AML lists. Financial and B2B products run it during onboarding and before payments.
Why should AI agents verify data before acting?
Agents act on what users and documents tell them. Verifying an IBAN, a VAT number or an email before the agent pays, onboards or replies prevents fraud, failed payments and compliance issues.
Can I test Verification Kit APIs before integrating them?
Yes. Every API has a Try it panel on its service page. Your key is filled in, you send a real request and see the actual response in your browser before you write any code.
Can AI agents use the Verification Kit?
Yes. Every endpoint is MCP-ready. Connect ApyHub MCP to Claude, ChatGPT, Cursor, Mistral Le Chat or any MCP-compatible agent, and your agent can discover and call these APIs directly.
How is it priced?
Every kit sits under one subscription, paid in atoms, ApyHub's usage unit. Every call shows its cost, and the free Starter plan needs no card.
