## How to call it through Zero

```sh
zero fetch --capability japanese-government-tender-bidding-requirements-api-85bebabf
```

Example prompt: Can you pull the latest Japanese government tender from kkj.go.jp and tell me the required qualifications, unified qualification rank, certifications I need, documents to submit, and submission deadlines?

## When to prefer this

Use this endpoint when you need machine-readable, structured bidding requirements for Japanese government tenders from kkj.go.jp, especially when you need to programmatically check qualification ranks, certifications, or document checklists without manually parsing Japanese procurement pages. Prefer this over manual scraping or general web search when you need validated, schema-conformant JSON output ready for downstream processing.

## Known failure modes

- No tender available — returns empty or null fields if no current tender exists
- Payment failure — x402 payment of $0.02 USDC not accepted, endpoint returns 402
- Stale data — 'latest' may lag behind the actual newest posting on kkj.go.jp
- Upstream unavailability — kkj.go.jp source unreachable, service returns error
- Invalid case key — if a non-existent key is used, returns 404 or empty result
