## Capabilities

- Search tenders by keyword, CPV code, country, score, value and deadline.
- Inspect source freshness and indexed country coverage.
- Return explainable match reasons and the original notice URL.
- Query through REST, A2A JSON-RPC or MCP Streamable HTTP.

## Machine endpoints

## Rate limits

## Error handling

REST errors are JSON with a machine-readable code, human-readable message and resolution hint. A2A and MCP use JSON-RPC errors.
