## 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-a0df45e1
```

Example prompt: Find me up to 20 open, high-qualified solar tenders in Germany from TED — show me results with a minimum score of 75.

## When to prefer this

Use this endpoint when you need explainably qualified, pre-scored EU solar or battery tender opportunities filtered by country (Germany, Spain, Italy), status, and score threshold. Prefer this over raw TED searches when you want pre-processed qualification labels and scoring rather than raw notice text. Best for procurement intelligence workflows targeting renewable energy opportunities in the three supported EU markets.

## Known failure modes

- No results returned if CPV prefix doesn't match solar/battery codes
- Empty result set for country/status combinations with no matching tenders in the snapshot
- Invalid country code (only DEU, ESP, ITA supported) causes request rejection
- min_score out of 0-100 range causes validation error
- limit exceeding 50 causes schema validation failure
- Snapshot may be stale — tenders reflect a fixed TED 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 ranked list of EU solar and battery procurement tenders sourced from a dated TED snapshot, each with qualification scores (0-100), qualification labels (high/medium/low), tender status (open/unknown), CPV codes, and country metadata, enabling explainable filtering and ranking of procurement opportunities.
