## 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 johto-data-api-uk-tenders-70107869
```

Example prompt: Pull the latest 10 UK public tender notices published since 2026-10-01 from Find a Tender Service so I can see which government buyers are actively procuring right now.

## When to prefer this

Use this endpoint when you need structured, paginated access to UK public sector tender notices from either the Find a Tender Service or Contracts Finder feed. It is ideal for B2G sales intelligence, procurement monitoring, and lead generation targeting UK government buyers. Prefer it over manual scraping of government portals or generic web crawl endpoints when you need clean structured data with CPV categories, contract values, and deadlines already parsed.

## Known failure modes

- No matching notices found for the given date range — returns empty data array and zero rows
- Invalid 'since' date format (must be YYYY-MM-DD) — schema validation error
- Invalid 'limit' value outside 1–25 range — schema validation error
- Invalid 'feed' value (must be 'fts' or 'cf') — schema validation error
- Upstream UK government feed unavailable — fetch fails and no charge is applied
- Malformed or expired cursor — may return an error or restart pagination

## How this service works
