> Read the zadávací postupy (procurement procedures) your Informační servis finds, the lhůty (deadlines) on Mé postupy and each tender's zadávací dokumentace with one API call each. Or have a workflow check NEN each morning and email you the new tenders.

Works with your own NEN account. Fous is an independent product.

## What you can build on NEN

### Get tenders from your Informační servis

Reads the Informační servis tab of Zadávací postupy, listing the procedures that match your saved criteria such as CPV codes, place of performance and estimated value.

- Takes: View: Aktuální dle lhůty podání, Zpřístupněno dnes or Vše
- Returns: System number, procedure name, contracting authority, procedure type, estimated value, submission deadline, link

### Get deadlines and calls for my procedures

Reads the Lhůty, Výzvy and Výsledky tabs of Aktivity u mých postupů for the procedures on Mé postupy.

- Takes: Procedure number (optional)
- Returns: Procedure number, procedure name, deadline type, deadline date and time, calls received, results published

### List a tender's documents and clarifications

Opens one procedure and reads the Zadávací dokumentace and Vysvětlení zadávací dokumentace tabs: which documents are published and which clarifications were given.

- Takes: Procedure number
- Returns: Document name, published date, block, clarification number, clarification date

### Ask for clarification of tender documents

Opens one procedure, prepares a Žádost o vysvětlení zadávací dokumentace with your question and sends it to the contracting authority.

- Takes: Procedure number, question
- Returns: Procedure number, sent at, message subject

## Automate NEN with a workflow

A [workflow](/product/workflows) runs your methods as one process, with nobody at the screen. A schedule or a call from your own system starts it, the steps run in order, and the result arrives in your inbox or in the systems you already use.

### New tenders from your Informační servis, every morning

Starts: Every weekday at 7:00

1. Get the tenders from your Informační servis in the Aktuální dle lhůty podání view.
2. Keep the procedures that were not there on the last run.
3. Email you the list with name, contracting authority, estimated value and submission deadline.

### Deadlines and new clarifications for Mé postupy

Starts: Every weekday at 8:00

1. Get the deadlines and calls for every procedure on Mé postupy.
2. For each procedure, list its documents and clarifications and keep those new since the last run.
3. Keep deadlines in the next 7 days and email you one summary per procedure.

### Published results, posted to your bid tracker

Starts: Every day at 18:00

1. Get the deadlines, calls and results for the procedures on Mé postupy.
2. Keep the procedures whose result appeared since the last run, and stop when there are none.
3. Post procedure number, name and result date to your webhook.

You can run a workflow by hand on every plan, Free included. Schedules and webhook triggers come with the paid plans, from $29 a month.

## Once built, one call from your code

Once you have built a [method](/product/methods), it is one POST to /v1/runs from your backend, or a tool an AI agent calls over MCP. This is what “Get tenders from your Informační servis” would look like.

Example request:

```
curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "nen.nipez.cz/get_information_service_tenders",
    "input": {
      "view": "Aktuální dle lhůty podání"
    }
  }'
```

Example response:

```
{
  "status": "completed",
  "data": {
    "view": "Aktuální dle lhůty podání",
    "procedures": [
      {
        "system_number": "N006/26/V00041872",
        "name": "Dodávka kancelářských potřeb 2027",
        "contracting_authority": "Statutární město Northwind",
        "procedure_type": "Dodávky",
        "estimated_value": 1850000,
        "currency": "CZK",
        "submission_deadline": "2026-11-27T10:00:00+01:00",
        "link": "https://nen.nipez.cz/verejne-zakazky/detail-zakazky/N006-26-V00041872"
      }
    ],
    "count": 1
  }
}
```

An example with invented data, not a ready-made endpoint. The method exists in your organization once you build it, and its name, inputs and fields follow your request.

## NEN’s own options

NEN has a public API, but it covers purchasing through e-catalogues under §215 of Act No. 134/2016: suppliers manage their e-catalogue, confirm offered values and get results. Its Swagger documentation is given on request to the NEN operator. Finding tenders, reading tender documents and submitting bids happen in the web application.

| Option | What it covers | What it takes |
| --- | --- | --- |
| Public API: e-catalogue purchasing | Supplier services ElectronicCatalog, TenderConfirmation, TenderConfirmatonHistory, TenderResults and Message, with notices sent through Azure Service Bus. | A request to the NEN operator for access to the Swagger documentation. Only for purchases made through e-catalogues. |
| Informační servis and email notifications | Saved criteria (procedure type, estimated value, CPV, place of performance, contracting authority, text) that list matching procedures and email them. | A user with the Účastník zadávacího postupu role. Daily emails go out no earlier than 23:00, with no guaranteed delivery time. |
| NEN by hand | Zadávací postupy, Aktivity u mých postupů, each procedure's tabs and supplier acts such as bids and clarification requests. | A registered supplier organisation, free to use, and a NIPEZ identity for each person who signs in. |

## Signing in to NEN

NEN signs suppliers in with Přihlásit se identitou NIPEZ (log in with NIPEZ identity): Czech and EU citizens use an electronic identity such as Bankovní identita or Mobilní klíč eGovernmentu, and people from outside the EU use a NIPEZ identity with Microsoft Authenticator. With Fous you sign in through NEN's own sign-in with your own identity, and the login is sealed with AES-256 and never shown to code or agents.

## Worth knowing

- **One identity per person**: The ministry ends username and password sign-in for suppliers and does not allow shared accounts. Each person signs in with their own identity and acts for the organisation through the roles it gives them.
- **Roles decide who can submit**: Only a user with the Účastník zadávacího postupu role can submit a bid or set up Informační servis. A user who only has Administrátor subjektu cannot see the supplier acts.
- **Bids are encrypted before sending**: Procedures under ZZVZ require encryption before a bid can be sent, files may total at most 2 GB, and after sending you see only the file names. Delivery counts when NEN accepts the bid.
- **Clarification requests have a cut-off**: The authority answers at least 5 working days (4 for below-threshold contracts) before the bid deadline, and need not answer a request received less than 3 working days before that.

## Frequently asked questions

### Does NEN have an API?

Yes, but only for purchasing through e-catalogues. Its supplier services manage the e-catalogue, confirm offered values and return results, and access to the documentation is by request to the NEN operator. Tenders, tender documents and bids are handled in the web application.

### How do I get alerts for new tenders in NEN?

Set up Informační servis with criteria such as CPV codes, estimated value, place of performance or contracting authority. Matches appear on its tab and can be emailed, no earlier than 23:00 each day. Procedures on Mé postupy notify you of each publication straight away.

### Can several people in our company share one NEN account?

No. NEN signs people in with a personal NIPEZ identity, and the ministry states that shared login details are not allowed. Each colleague gets their own access, which an Administrátor subjektu manages under Správa osob.

### By when must I ask for clarification of tender documents?

At least 3 working days before the authority's own limit, which is 5 working days before the bid deadline, or 4 for below-threshold contracts. NEN still lets you send a later request, but the authority need not answer it.

### Is Fous affiliated with Ministerstvo pro místní rozvoj?

No. Fous is an independent product. You use it with your own NEN access, and a method reads and does only what that account can.

Fous is an independent product: it is not affiliated with, endorsed by or sponsored by the operator of NEN (Ministerstvo pro místní rozvoj). The name is used only to say which system this page is about. Something here wrong or out of date? Write to legal@fous.com.
