## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability zinin-tender-alert-monitor-ade015a0 -d '<json body>'
```

Example prompt: Check for any new public procurement tenders matching 'cybersecurity software' using the baseline key 'cybersec-watch-2024' — only tell me about ones that are new since the last run.

## When to prefer this

Use this endpoint when you need incremental monitoring of public procurement tenders — specifically when you want to detect only newly published tenders against a previously established baseline, rather than retrieving the full list every time. It is particularly suited for automated agents that poll on a schedule and need to avoid re-processing already-seen tenders. Prefer this over generic web search when you want structured tender data (CPV codes, buyer, deadlines) with built-in change-detection logic.

## Known failure modes

- Baseline key not found — first run creates a new baseline instead of reporting new tenders
- No new tenders found — returns results with isNew=false and empty newTendersCount
- Filter too broad — may return large counts without meaningful new signals
- Network or upstream procurement data source unavailable — may return error field with description
- Invalid or missing filter parameters — may result in empty results or error response

## How this service works

Pay-per-call data & tool APIs

## Output

Returns a JSON object with metadata (run duration in ms, settlement status, item count) and a results array. Each result includes whether the tender is new, a human-readable summary, the baseline key, baseline creation status, current tender count, checked timestamp, and — for new tenders — title, URL, buyer, buyer country, CPV code, publication number, publication date, and deadline.
