Verification Kit.
3 · CheckCheck the data before your product acts on it. When your product or your agents onboard customers, pay suppliers or send messages, every input needs to be real. The Verification Kit is the trust layer between a model's output and a real-world action.

Convert and Get Crypto Prices API
Crypto Prices Converter gives you live spot prices and conversion results for supported cryptocurrencies and fiat currencies. Send a quote currency and one or more symbols to get current prices back, or pass a source currency, target currency, and amount to calculate a conversion. The spot prices endpoint accepts vs as usd, eur, gbp, btc, or eth, plus an optional symbols query string. The response includes the requested vs, a source string, and a prices object keyed by symbol. Each symbol entry returns price, with optional change24h and marketCap values when available. The conversion endpoint takes required from and to query parameters, plus an optional amount. The response returns from, to, amount, result, usdPerFrom, and usdPerTo, which makes it useful for displaying exchange values or normalising balances across assets. Use Crypto Prices Converter when you need current pricing in a trading dashboard, a portfolio view, a checkout flow, or an internal finance tool that compares coin values without maintaining your own rate feed.
API ForgeVerifiedCrypto Market Sentiment Index API
Crypto Sentiment Index returns the current crypto market sentiment as a numeric value, a classification label, and a Unix timestamp in milliseconds. Send an optional limit query parameter to control how many recent entries you want back, up to 30. Use it when you need a lightweight signal for dashboards, trading bots, alerts, or market commentary. The response includes a source string and an entries array, so you can trace where the sentiment data came from and iterate over the latest readings without extra parsing. Each entry contains value from 0 to 100, classification, and timestamp. That makes it easy to compare the current reading with historical snapshots, threshold alerts, or other market indicators in your own app. If you need a compact sentiment feed for crypto products, Crypto Sentiment Index keeps the response focused on the fields that matter.
API ForgeVerifiedGet Global Crypto Market Overview API
Crypto Market Cap returns the global cryptocurrency market snapshot in a chosen quote currency. Send vs as usd, eur, gbp, btc, or eth, and get back the current market data in that denomination. The response includes source, vs, totalVolume, btcDominance, ethDominance, totalMarketCap, marketCapChange24h, and activeCryptocurrencies. Numeric fields may be null when the upstream source does not have a value available, so you can handle missing market data without guessing. Use Crypto Market Cap when you need to show a dashboard, drive portfolio analytics, or annotate a crypto summary with current dominance and capitalization figures. Because the output is already normalised around a single vs currency, it fits cleanly into charts, market overviews, and comparison views. It is a lightweight read-only endpoint for applications that need a fast global crypto market reference rather than per-asset pricing or exchange order books.
API ForgeVerifiedWhich Verification API do you need?
The question you arrived with, and the API that answers it.
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.
