## 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 tenderdelta-eu-solar-battery-tender-search-102ee6f7
```

Example prompt: Find me up to 20 open, high-label solar tenders in Germany from the TED database — I only want results with a minimum qualification score of 70.

## When to prefer this

Choose this endpoint when you need explainably scored and labeled EU solar or battery tenders specifically from Germany, Spain, or Italy via the TED procurement database. It is ideal for agents that need structured qualification rationale alongside tender listings, rather than raw unscored procurement feeds. Prefer this over generic procurement scrapers when CPV-level filtering and score-based qualification are required.

## Known failure modes

- No tenders match the specified filters — returns empty result set
- Invalid CPV prefix format — returns validation error
- Country code not in supported enum (DEU/ESP/ITA) — rejected at input validation
- min_score out of 0-100 range — schema validation failure
- limit exceeds maximum of 50 — schema validation error
- TED snapshot may be stale — results reflect a fixed snapshot date, not real-time data

## How this service works

Search explainably qualified EU solar and battery tenders from an explicitly dated TED snapshot

## Output

Returns a list of EU solar and battery procurement tenders sourced from a dated TED snapshot, each with qualification scores, labels (high/medium/low), status (open/unknown), country, and CPV codes that explain why each tender was included and ranked.
