Pick the workflow by input and returned artifact: an API query becomes an Evidence Packet, a prescreen form becomes source-linked candidate programs, a saved topic becomes a reminder, and a client inquiry becomes advisor handoff context.
Connect/install paths: Claude / Cursor / ChatGPT / Codex setup guides, REST quickstart, and Playground preview.
Audiences: tax advisors (zeirishi) / administrative scriveners (gyoseishoshi) / SMB owners / VC & M&A advisors / AI agent developers. See audience playbooks →
jpcite is the Japanese-regulation packet bank AI agents find and buy — a context-compression layer before an AI reads Japanese institutional evidence, returning small Evidence Packets before an AI writes its answer over long Japanese institutional evidence. REST, MCP, OpenAPI Actions, widgets, webhooks, and datasets are entry surfaces for saved outputs a user can inspect, hand off, or automate.

|---|---|---|---|
| Evidence Packet | Program ID, keyword, or law name | Primary-source URLs, fetched_at, known gaps, professional-scope fences, citation candidates | Live playground / REST / MCP |

| Company Public Fact Brief | Target company list or counterparty name | Enforcement history, subsidy adoption, unverified scope, analyst memo | REST batch / MCP |
| Monthly Client Review | Client name, industry, and region | Subsidy, tax, loan candidates, deadlines, changes, client-question draft | Saved search / Email / API |
| Application Evidence Pack | Region, industry, investment amount, and use of funds | Candidate programs, exclusion rules, stacking cautions, required docs, interview questions | Live playground / Widget |
| Funding Compatibility | Program IDs, candidate programs, or funding use | Mutual exclusions, missing prerequisites, unknowns, source material to verify | REST / MCP |
| Invoice Counterparty Check | Invoice number, corporate number, or vendor CSV | Registration status, identity match, history, rows needing review | REST / MCP / Dashboard |
| Funding Traceback / Source Receipt | Source URL, program ID, law ID, or article ID | Fetched time, content hash, known gaps, and recheck targets | Evidence Packet / audit log |
| Law / Case Citation Candidates | Law name, article, program, or issue keyword | Citation candidates, related articles, related cases, professional-review notes | REST / MCP |
| Amendment/Saved Search Alerts | Watch keywords, laws, or programs | Amendment diffs, impacted candidates, notification log, webhook delivery | Email / RSS / Webhook |
| Cost/Payment Control | API key, Stripe, wallet, or x402 payload | Usage, caps, duplicate-charge prevention, payment verification, retry status | Stripe Checkout / Headers / Dashboard |
| Agent Handoff | Claude, Cursor, ChatGPT, Codex, or another agent | Shared evidence surface across REST, MCP, and OpenAPI Actions | MCP / OpenAPI Actions |
jpcite is priced by packet granularity, with the AI agent route as the first route. Each line below is a logical pricing unit; the smallest atomic unit is one source-linked fact. The output cards further down are the concrete artifacts.
| Product line | Price | What it is |
|---|---|---|
| Raw evidence | from ¥3 | Smallest atomic unit: one source-linked fact with source_url and fetched_at. |
| Citation | free–¥10 | Citation candidates and related articles for a law name, article, or issue. |
| Verified receipt | ¥10–30 | Source receipt with content hash and freshness record for audit and review. |
| LLM Expansion Kit | ¥30 | Evidence bundle sized for an AI agent to expand into its own answer. |
| Standard Kit | ¥60 | Standard packet across major public rows for a single workflow. |
| Pro DD (due-diligence) | ¥120 | 360-degree due-diligence packet from public information on one entity. |
| Deep DD | ¥240 | Deepest due-diligence packet with the widest source coverage. |
| Path | Audience | User input | Returned artifact | Setup time | Details |
|---|---|---|---|---|---|
| API + MCP | AI developers / enterprise workflows | Natural-language query, filters, corporate number, or program IDs | Evidence packet with source URLs, fetched_at, rules, and matched records | 5 minutes | Docs → |
