What you can do with Doxis AI.dp (Klippa DocHorizon) in Claude and ChatGPT

For finance and operations teams who extract data from invoices, receipts and documents with Doxis AI.dp (Klippa DocHorizon).

Pull supplier, date and totals from an invoice or receipt

The AI sends an invoice or receipt and returns merchant, customer, dates, totals, VAT, line items and currency as structured data.

Changes data

Read a bank statement or payslip into data

The AI extracts a bank statement (balances and every transaction) or a salary slip (gross, net, deductions). The result holds personal data, so handle it with care.

Changes data

Check which fields a capture model returns

The AI lists the enabled capture models and configurations, and reads the JSON schema of a model. You can see if a field, such as the VAT number, is returned.

Validate an e-invoice or convert it to JSON

The AI checks an e-invoice XML or hybrid PDF against its standard, such as EN 16931 or XRechnung, and lists each broken rule. It can also convert it to Universal Invoice JSON.

Changes data

Look up a company in the Peppol directory

The AI searches the public Peppol directory by name or identifier, and looks up one participant to see which document types it can receive.

Queue a document, check its job or delete it

The AI submits a document for asynchronous capture, checks the job status and reads the result. It can delete the job with its stored documents.

How do I connect Doxis AI.dp (Klippa DocHorizon)?

Before you connect

The login page asks for your Doxis AI.dp API key and Hosting region.

Find the key in the Doxis AI.dp platform (dochorizon.klippa.com) under Settings → Project → API → Credentials. A new account gets EUR 25 of free credit. Keys belong to one project; if you restricted the credential to certain IP addresses, remove that restriction (this server calls from shared Cloudflare addresses). Choose Germany only if your project was created in the Germany region. Identity, bank statement and salary slip captures return personal data to your AI client; documents are processed by Doxis AI.dp under your project's data-retention settings. Your key is used only to call the Doxis AI.dp API on your behalf; it is never shown to anyone.

https://klippa-dochorizon.usefulapi.io/mcp

Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Doxis AI.dp API key and Hosting region. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

Pricing

Plan	Price	Limit
Free	$0	50 tool calls / month
Proper project	$9/mo · $90/yr	10,000 tool calls / month
Pro+per project	$39/mo · $390/yr	100,000 tool calls / month

Each paid plan covers this Doxis AI.dp (Klippa DocHorizon) server only. Ask your AI to run dochorizon_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with dochorizon_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with dochorizon_upgrade before then undoes the cancel.

Your usefulapi plan · 4

Usage status (free-tier meter)dochorizon_usage_status
Report the caller's current usage: the plan, calls used this month, the limit of the plan (the free monthly cap or the Pro fair use limit), remaining, and whether the limit is reached. Read-only; does not count against the meter.
Request a missing featuredochorizon_request_feature
Tell usefulapi that the user needs something the Doxis AI.dp (Klippa DocHorizon) tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter.
Upgrade to Pro or Pro+dochorizon_upgrade
Get a paid plan for Doxis AI.dp (Klippa DocHorizon) (the free tier caps monthly usage). Pro: 10,000 tool calls a month, for normal use — plan "monthly" ($9/month) or "yearly" ($90/year, 2 months free). Pro+: 100,000 tool calls a month, for automations and heavy use — plan "plus" ($39/month) or "plus_yearly" ($390/year). Without a plan it returns both Pro and Pro+, each with a payment link, for the user to choose; with a plan, one link. An existing Pro subscription changes to Pro+ in place: call without confirm first, as the reply states the exact charge for this account (the price difference for the rest of the period, or in a free Pro trial the full Pro+ price, as the trial ends); then call with confirm: true. Cancel any time: the plan then runs to the end of the paid period, so it also suits a one-time job. A link opens Stripe Checkout in the browser; after payment the account upgrades automatically. Does not count against the meter.
Cancel the Pro subscriptiondochorizon_cancel_subscription
Cancel the caller's Doxis AI.dp (Klippa DocHorizon) Pro subscription at the end of the paid period (no refund for the current period; Pro continues until then, then the free tier applies). Requires confirm: true. Run dochorizon_upgrade later to undo the cancel before the period ends. Does not count against the meter.

FAQ

What can I do with Doxis AI.dp (Klippa DocHorizon) in Claude or ChatGPT?

Pull supplier, date and totals from an invoice or receipt. Read a bank statement or payslip into data. Check which fields a capture model returns. Validate an e-invoice or convert it to JSON. Look up a company in the Peppol directory. Queue a document, check its job or delete it. See what you can do for the details.

Is this an official Doxis AI.dp (Klippa DocHorizon) product?

No. usefulapi is an independent service. It is not affiliated with or endorsed by Doxis AI.dp (Klippa DocHorizon). The server calls the Doxis AI.dp (Klippa DocHorizon) API with your own Doxis AI.dp (Klippa DocHorizon) access, so it sees only the data that your account can see.

Can I connect Doxis AI.dp (Klippa DocHorizon) to Claude or ChatGPT?

Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.

What do I need to connect?

The login page asks for your Doxis AI.dp API key and Hosting region. See Before you connect for where to find them.

Do I put my Doxis AI.dp (Klippa DocHorizon) key or an Authorization header in the client config?

No. Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Doxis AI.dp API key and Hosting region. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

How do you keep my Doxis AI.dp (Klippa DocHorizon) credentials?

The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Doxis AI.dp (Klippa DocHorizon) API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in Doxis AI.dp (Klippa DocHorizon).

Can the AI change my Doxis AI.dp (Klippa DocHorizon) data?

Yes, if you approve it. 16 of the 30 Doxis AI.dp (Klippa DocHorizon) tools can create or change data. The other 14 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.

What does it cost?

The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this Doxis AI.dp (Klippa DocHorizon) server only. Cancel any time: your paid plan then runs to the end of the paid period. Run dochorizon_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run dochorizon_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run dochorizon_cancel_subscription. Your paid plan continues to the end of the paid period.

What if a Doxis AI.dp (Klippa DocHorizon) tool that I need is missing?

Tell the AI what you wanted to do. It can send the request with dochorizon_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.

Which AI clients can I use?

Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.

This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
