How this service works
Structured bidding requirements for a Japanese government tender (kkj.go.jp): qualifications, unified qualification rank (A-D), required certifications, document checklist, deadlines, bid method — as validated JSON. Use path segment 'latest' for the newest tender, or find case keys for free at https://5.75.142.199.sslip.io/cases?limit=20 (field: key). Docs: https://5.75.142.199.sslip.io/llms.txt / 日本の官公需(入札)案件の応募要件を構造化JSONで返す。
Output
A validated JSON object containing: an array of qualification requirements (including unified rank and regional requirements), the unified qualification rank string (e.g. 'A,B,C' or null), required certifications (e.g. ISO27001, ISMS), a list of required documents, performance period, an array of deadline objects (label + value), contact information, and the bid method (e.g. general competitive bidding).
Example use cases
Check competitor qualification rank requirements
“Pull the latest Japanese government tender and compare the unified qualification ranks we need versus what our competitors typically have—tell me if we're A-ranked eligible or if we need to upgrade certifications first.”
Build compliance checklist for tender submission
“Get the newest kkj.go.jp tender requirements and create a checklist of every document we need to submit, all required certifications we're missing, and the exact deadline so our team can start gathering everything today.”
Assess ISO certifications gap for bid eligibility
“Check the current Japanese government tender on kkj.go.jp and tell me what ISO and ISMS certifications are mandatory—and whether our existing credentials match or if we need to pursue new certifications before we can bid.”

Endpoint
GEThttps://5.75.142.199.sslip.io/paid/requirements/latestWhen to prefer
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.
Side effects
- 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
