Pay-As-You-Go AI Document Processing API

Claix pricing at a glance

With BYOK, the cost is:

€0 Claix processing fee
+
your AI provider's token and service charges

BYOK does not mean AI model usage is free. It means Claix does not add an extra document-processing charge when you use your own supported provider API key. Claix does not charge an additional processing fee for BYOK. Customers remain responsible for their AI provider's token usage and provider charges.

What is pay-as-you-go document processing?

Pay-as-you-go, also called usage-based pricing, means you pay based on what you actually consume.

For document processing, that means:

You process a document
        ↓
You pay for that request

You do not process documents
        ↓
You do not pay a document-processing charge

This is useful because document volume is rarely perfectly predictable.

A company may process:

• 10 supplier invoices this month.
• 250 invoices next month.
• Hundreds of files during onboarding.
• A large batch during an audit.
• No files at all during a quiet period.
• A few high-value legal contracts.
• A sudden spike from a customer campaign.

A monthly flat fee can make sense for businesses with very stable, very high usage. But for startups, developers, agencies, internal teams, pilots, and growing workflows, pay-as-you-go pricing often provides a lower-risk way to start.

Usage-based pricing aligns cost with usage: when you use less, you pay less; when your workflow grows, your cost grows with it.

Why avoid a €300 monthly plan?

Many document-processing and AI automation platforms use monthly plans.

A typical pricing structure might look like:

Starter plan: €99 per month
Professional plan: €199 per month
Team plan: €300 per month
Enterprise plan: custom pricing

For a company processing thousands of documents every month, a fixed plan may be acceptable.

But many teams do not start there.

They are still testing whether AI document processing works for their invoices, customer files, spreadsheets, contracts, or internal workflows.

The biggest advantage is not only the price.

It is the ability to test, iterate, and scale without paying for unused capacity.

What does Claix process?

Claix is built for document and data workflows.

The goal is to transform messy, human-oriented files into structured information that software can use.

    ↓
Database, CRM, ERP, automation, or application

What does one processing request include?

A Claix processing request is not just raw text extraction.

It is designed to help you convert document content into a structured result your workflow can use.

For example, a PDF invoice can become:

{
  "invoice_number": "INV-2026-00456",
  "supplier_name": "Example Supplies Ltd",
  "invoice_date": "2026-03-14",
  "due_date": null,
  "total_amount": 1284.5,
  "currency": "EUR",
  "purchase_order_number": "PO-2049"
}

That output can be sent directly to:

• A database.
• A CRM.
• An ERP.
• n8n.
• Make.
• Zapier.
• Supabase.
• A custom backend.
• An internal tool.
• A review queue.
• An approval workflow.

Claix helps you move from asking a model to read a document to extracting the exact fields your workflow needs.

Pricing examples

Example 1: 20 invoice PDFs per month

A small business receives 20 invoices each month.

20 PDF processing requests × €0.15
= €3.00 per month

Instead of paying a high flat subscription, the business pays for the invoices it actually receives.

Example 2: A mixed document workflow

An agency processes:

• 40 PDF documents.
• 30 Excel or CSV files.
• 20 Word or text documents.
• 10 image files.

40 PDFs × €0.15 = €6.00
30 Excel/CSV files × €0.15 = €4.50
20 text documents × €0.10 = €2.00
10 images × €0.10 = €1.00

Total = €13.50

Example 3: Contract follow-up questions

A legal or procurement team has already processed its contracts and asks 30 follow-up questions.

30 Document Context queries × €0.03
= €0.90

Typical questions may include:

Does this agreement renew automatically?
What is the early termination penalty?
What payment terms are listed?
Which party is responsible for maintenance?

Example 4: Knowledge Space queries

A supplier workspace contains contracts, invoices, price lists, and purchase orders.

The team asks 25 cross-document questions.

25 Knowledge Space queries × €0.03
= €0.75

Example questions:

Which invoice does not match the contracted price?

What is the total billed by this supplier across all invoices?

Which contracts expire in the next 90 days?

Example 5: BYOK

A developer uses their own Gemini, OpenAI, Claude, Grok, or another supported provider key.

Claix processing fee:
€0

Customer cost:
Only the selected provider's token and service charges

This is especially useful for teams that already have an approved AI provider account or want direct control over provider billing. Claix does not charge an additional processing fee for BYOK. Customers remain responsible for their AI provider's token usage and provider charges.

Pay-as-you-go vs flat-rate pricing

A fixed plan offers predictable monthly spending.

A pay-as-you-go model offers flexibility.

For many document workflows, flexibility is more important early on because usage changes constantly.

Why €0.03 document queries matter

Document processing is not always a one-time activity.

A team may process a contract today and need answers from it weeks later.

They may process an invoice now and later need to check:

• The due date.
• The payment terms.
• The reason for a discrepancy.
• The relevant line item.
• Whether a contract condition applies.

With Claix, the initial document-processing request creates structured data. If document context is enabled, you can ask focused questions later for €0.03 per query.

This avoids having to reprocess a document from scratch or send the entire file to an AI provider again for every question.

Process once
    ↓
Keep document context available
    ↓
Ask a focused question when needed
    ↓
Pay €0.03 per query

The same approach applies to Knowledge Spaces, where related documents can be queried together.

Pay only for the data you need

The real advantage of usage-based document processing is control.

You can start with a small, narrow workflow:

Invoice PDF
    ↓
Extract supplier, invoice number, total, and currency
    ↓
Validate values
    ↓
Save to database

Then expand only when the workflow proves valuable:

Invoice PDF
    ↓
Extract structured fields
    ↓
Compare against purchase order
    ↓
Check contract pricing
    ↓
Send exceptions to finance
    ↓
Query supplier documents when needed

Your costs follow the workflow's growth.

You do not need to buy an enterprise plan before you know whether the automation is useful.

Claix for invoice processing

Invoice extraction is one of the most common pay-as-you-go use cases.

A company can process a supplier invoice PDF for €0.15 and extract fields such as:

• Invoice number.
• Supplier name.
• Issue date.
• Due date.
• Tax amount.
• Total amount.
• Currency.
• Purchase order reference.
• Customer reference.

A workflow can then use standard application logic:

If invoice_number is missing:
    send to review

If total_amount does not match purchase order:
    create exception

If supplier is unknown:
    request validation

If all checks pass:
    continue with approval

The AI helps interpret the document.

Your workflow controls the business decision.

Claix for contracts

Contract processing can be expensive when it requires a high monthly plan, especially for teams that only review contracts occasionally.

With Claix, each PDF contract can be processed for €0.15.

The workflow may extract:

• Parties.
• Start date.
• End date.
• Renewal terms.
• Payment terms.
• Termination penalties.
• Jurisdiction.
• Commercial conditions.
• Obligations.
• Review status.

After processing, the team can ask targeted questions for €0.03 each.

What is the early termination penalty?

Does the contract renew automatically?

When does this agreement expire?

This is useful for legal, procurement, sales, operations, and contract-management workflows.

Claix for Excel and CSV imports

Excel and CSV files are often inexpensive to process but expensive to clean manually.

They may contain:

• Inconsistent column names.
• Different languages.
• Abbreviations.
• Legacy exports.
• Missing fields.
• Repeated rows.
• Supplier-specific templates.

Claix can map spreadsheet data into the fields your system expects.

"Client", "Customer", and "Account Name"
        ↓
customer_name

"Invoice Total", "Amount Due", and "Grand Total"
        ↓
total_amount

At €0.15 per Excel or CSV processing request, this can be a practical alternative to manual cleanup or a high fixed monthly contract.

Claix for image and receipt processing

A photographed receipt, form, or scanned document can be processed for €0.10.

Useful cases include:

• Expense receipts.
• Delivery notes.
• Mobile document uploads.
• Scanned forms.
• Screenshots.
• Business cards.
• Identity documents.
• Product labels.
• Customer evidence files.

A workflow can extract fields such as:

merchant_name
purchase_date
total_amount
currency
reference_number

If the image is unreadable, incomplete, or missing a required value, the workflow can route it to manual review.

Claix for text, HTML, and XML

Not every document-processing workflow starts with an uploaded file.

Many systems receive data through:

• Email bodies.
• Web forms.
• HTML pages.
• CRM exports.
• XML feeds.
• Webhooks.
• Support tickets.
• Internal tools.
• Raw text messages.

Claix can process TXT, HTML, and XML content for €0.10 per request and turn it into structured information.

Example:

Incoming HTML form
    ↓
Claix extracts name, email, request type, and reference number
    ↓
Workflow creates CRM record

This gives automation builders a pay-as-you-go way to standardize messy incoming content.

BYOK: free Claix processing with your own key

Bring Your Own Key, or BYOK, lets you use your own AI provider account.

You select:

• The provider.
• The model.
• The API key.
• The account that receives the AI bill.

Claix still provides the document workflow.
