Common questions
Is vergabe-api: German public procurement notices safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.4.0) reached the registry 2 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?

vergabe-api
German public procurement notices, above and below the EU thresholds, as a normalised JSON API for software agents and procurement tools. Paid per call with x402 (HTTP 402, USDC). No account, no API key, no subscription.
Base URL: https://vergabe-api.applehorsefrog.workers.dev (a branded domain under viono-insights.de will follow). Payments settle on Base mainnet in USDC since 2026-09-14; the facilitator is PayAI.
What you get
Every day roughly 1,000 notices are published on the official German notification service (Datenservice Öffentlicher Einkauf, eForms-DE). The raw feed is a ZIP of XML files, 20 MB per day, with organisation contacts, lots, deadlines and classifications scattered over UBL extensions. This API turns each notice into one flat record:
| field | meaning |
|---|---|
id, notice_id, version | notice UUID and version |
published, issue_date | publication day of the export, issue date from the notice |
kind | competition (calls for tenders), result (awards), planning, change |
notice_type, subtype, procedure, legal_basis, nature | eForms codes (cn-standard, open, vgv, works ...) |
title, description | German text, personal contact data removed |
cpv_main, cpv_additional | CPV codes without check digit |
buyer_name, buyer_type, buyer_city, buyer_postal, buyer_nuts, buyer_website | contracting authority (organisation level only) |
place_nuts, place_city | place of performance |
estimated_value, currency | if stated |
deadline_date, deadline_time, deadline_kind | earliest lot deadline; tender or participation |
documents_url, submission_url | where the tender documents live |
lots | array of lots with title, CPV, NUTS, value, deadline, period |
winners, total_awarded | for award notices, organisation names only |
source_url | the original notice at oeffentlichevergabe.de |
Coverage on a sample day (2026-09-10): 1,067 notices, 589 calls for tenders, 569 of them with a submission deadline, 1,036 with CPV, 985 with NUTS.

Paying with x402
A request without payment returns 402 with a PAYMENT-REQUIRED header describing the amount (USDC), network and receiving address. Any x402 client handles this automatically, for example @x402/fetch:
import { wrapFetchWithPaymentFromConfig } from "@x402/fetch";import { ExactEvmScheme } from "@x402/evm"; import { privateKeyToAccount } from "viem/accounts";
const account = privateKeyToAccount(process.env.PRIVATE_KEY as 0x${string}); // holds USDC on Base const fetchWithPay = wrapFetchWithPaymentFromConfig(fetch, { schemes: [{ network: "eip155:8453", client: new ExactEvmScheme(account) }], }); const r = await fetchWithPay("https://vergabe-api.applehorsefrog.workers.dev/v1/notices?cpv=72"); console.log(await r.json());
Prices are in USD and settled in USDC on Base (eip155:8453); there are no other fees on our side. The same code runs against Base Sepolia by setting X402_NETWORK=eip155:84532 and X402_FACILITATOR=https://x402.org/facilitator in wrangler.jsonc.
MCP server
Two ways to use the data from an MCP client (Claude Desktop, Claude Code, Cursor, any MCP host):
Remote, free tools only (no install): Streamable HTTP endpoint https://vergabe-api.applehorsefrog.workers.dev/mcp with sample_tenders, tender_stats, describe_api. The paid tools are listed there too but only return the payment requirements, because the remote server has no wallet.
Local, with paid tools (stdio, Node 20+): the client pays per call from a wallet you control.
{"mcpServers": { "vergabe": { "command": "npx", "args": ["-y", "github:applehorsefrog/vergabe-api"], "env": { "VERGABE_PAYER_KEY": "0x " } } } }
Tools: search_tenders ($0.01 per call, all filters of /v1/notices), get_tender ($0.002), sample_tenders, tender_stats, describe_api (free). Without VERGABE_PAYER_KEY the paid tools return the x402 payment requirements and the HTTP URL instead of data. Use a dedicated low-balance wallet for the key; the server never sends it anywhere, it only signs USDC transfer authorisations (EIP-3009) for the exact price of each call. Source: mcp/server.mjs.
