Developer Integration

API vs SDK — two different integration models

Direct HTTP calls. No SDK to install. Requires Basic plan for API access.

JavaScript
// No npm install required
const res = await fetch(
  'https://anonym.legal/api/presidio/anonymize',
  {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${process.env.ANONYM_LEGAL_API_KEY}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      text: 'Contact John at john@acme.com',
      language: 'en',
      operators: { PERSON: 'replace', EMAIL_ADDRESS: 'hash' }
    })
  }
);
const { anonymized_text, items } = await res.json();

Base URL: https://anonym.legal/api/presidio

Auth: Authorization: Bearer ANONYM_LEGAL_API_KEY

MCP npm: @anthropic-ai/mcp-server-anonym-legal

Operators: replace · redact · hash · encrypt (AES-256) · mask · keep

cloak.business — Official SDKs

// Anonymize text
const result = await cloak.anonymize({
  text: 'Contact John at john@acme.com',
  operators: { PERSON: 'replace', EMAIL_ADDRESS: 'hash' }
});

// Deanonymize response from AI

How Tokens Work

Same token model for both products

What is a token?

One token = one entity detected and anonymized. A document with 10 names, 5 emails, and 3 phone numbers uses approximately 18 tokens.

Tokens roll over

Unused tokens carry over to the next month and never expire while your subscription is active.

Top-up anytime

Buy additional tokens without changing your plan. Basic: €1 = 250. Pro: €1 = 300. Business: €1 = 350.

Track usage

Monitor token consumption in your dashboard. The get_balance MCP tool (anonym.legal) returns your current balance directly in your AI tool.

Frequently Asked Questions

Both products cost the same — why would I pick one over the other?

The choice is purely about capabilities. anonym.legal is simpler: REST API, 7 MCP tools, text-only, no SDK required. cloak.business adds JS and Python SDKs, 10 MCP tools (including image and batch), image OCR, a Chrome Extension that works on the free plan, and RSA-4096 asymmetric encryption. Same budget, more features with cloak.business — but anonym.legal is the simpler integration if you don't need those extras.

Can I use the Chrome Extension on the free plan?

Yes — cloak.business's Chrome Extension works on all plans including the free €0 tier. It uses your token balance. The free plan includes 200 tokens per 30-day cycle, which covers typical personal usage of ChatGPT, Claude, and Gemini for light document work.

Does anonym.legal have a JavaScript or Python SDK?

No. anonym.legal provides a REST API only — direct HTTP calls with no official SDK. If you need an SDK with full TypeScript types, automatic retries, and async Python support, use cloak.business (@cloak-business/sdk on npm, cloak-business on PyPI).

What is the batch limit per plan?

Free: 2 texts per call. Basic: 5. Pro: 10. Business: 50. Enterprise plans support up to 100 texts per batch call. These limits apply to both anonym.legal and cloak.business.

When does MCP Server access unlock?

MCP Server is available on Pro (€15/mo) and Business (€29/mo) for both products. The free and Basic plans include the REST API and Chrome Extension (cloak.business) but not the MCP Server integration for Claude Desktop, Cursor, and other AI coding tools.

Can I use both products at the same time?

Yes — they are separate accounts with separate API keys. Some teams use anonym.legal for developer MCP pipelines and cloak.business for the Chrome Extension and image workflows. There is no bundle pricing; each is billed independently.

Is there a commitment period?

No. All plans are month-to-month. Cancel anytime. Unused tokens roll over until you cancel.

Start free on either product

Both start at €0. Upgrade when your workflow needs more tokens, MCP tools, or batch capacity.

Not sure? Read the FAQ or see the setup docs.

Considerations: API limits reset monthly; consider usage spikes during peak processing. Free tier is rate-limited — however, it is suitable for evaluation and small projects. Enterprise custom pricing available on request.
