Smart Utilities for
CRM Workflows

Normalize phone numbers, classify first names, parse and enrich person names, validate email addresses — via REST API, no AI model, no external dependencies. One API key, all five services, one shared quota.

Five APIs, one key

All services run on the same servers, share the same quota and require only a single API key.

Phone Format3 credits/request

Normalize phone numbers

Phone numbers are converted to E.164 format, country code is detected and optionally written back directly to Zoho CRM. Supports single and batch requests.

  • E.164 & national formats
  • Country code detection
  • Zoho CRM integration
  • Batch up to 100 (sync) / 500,000 (async)
POST /v1/format-phone

"+49 89 12345678" → "+4989123456789"

  • Confidence score per result
  • Composite-name support
  • Batch up to 100 (sync) / 500,000 (async)

  • "Lastname, Firstname" format
  • Batch up to 100 (sync) / 500,000 (async)

Name Intelligence3 credits/request

Enrich names for CRM personalization

Goes beyond parsing: generates ready-to-use formal and informal greetings, a display name, and a confidence score — built for mail-merge and 1:1 personalization at scale.

  • Formal & informal salutations
  • Confidence score + review flag
  • Firstname/lastname swap detection
  • Batch up to 500 (sync) / 500,000 (async)

Email Intelligence6 credits/request

Validate email addresses

Multi-step validation via syntax, DNS/MX check, disposable detection, role mailbox detection and optional SMTP probe. GDPR-compliant — no raw data stored.

  • Syntax + DNS/MX check
  • Disposable & freemail detection
  • Policy-configurable (allow/warn/block)
  • Batch up to 100 (sync) / 500,000 (async)
POST /v1/email/validate

"info@mailinator.com" → {status: "risky", reason: "disposable_email"}

One quota, five APIs — not five bills

Most competitors sell each API as a separate product with its own subscription. Toolbox pools everything into one plan.

QuotaOne shared pool across all 5 APIsSeparate quota per API, bought and tracked independently
API keys1 key for everything1 key per API/product
Billing currencyEUR, VAT handled at checkoutUsually USD — FX risk on every invoice
Unused capacityAutomatically available to any of the 5 APIsLocked to the API it was bought for

Up and running in three steps

No technical setup. No code on your end.

1

Subscribe

Choose a plan, pay by credit card or SEPA. Your API key is automatically generated and available in the customer portal.

2

Add your API key

Store the key once as an org variable in your CRM or as an environment variable in your app. One-time setup, no server required.

3

Start using it

Use all five APIs via REST. Credits are shared, usage is visible in the portal, CSV export included.

Simple, transparent pricing

Cancel anytime. No setup fee. Billed in EUR — no FX risk on your invoice.

Gender API and Name Parser cost 1 credit per request. Phone Format and Name Intelligence cost 3 credits per request (E.164 normalization with optional CRM write-back; salutation generation, confidence scoring and swap detection go well beyond basic parsing). Email Intelligence costs 6 credits per request (real SMTP connection to verify deliverability).
