API playground — verify behavior with anonymous 3 req/day

Try it free with anonymous 3 req/day per IP (no registration, no API key, resets JST next-day 00:00). Call https://api.jpcite.com/v1/* directly from the browser to inspect the Evidence Packet structure, source_url / source_fetched_at / known_gaps, and the professional-practice-law fence envelope. After 3 calls, continue by issuing an API key (fully metered at ¥3.30/unit).

Quick use

  • Anonymous calls are limited to 3 requests per day per IP; use an API key for larger evaluations.
  • Keep source_url and _disclaimer fields in sample responses; they are part of the integration contract.

This is the production API. Requests reach api.jpcite.com immediately and consume the anonymous quota (3/day); it resets at JST next-day 00:00. You can check your remaining quota with the indicator on the live page.

3-step Evidence wizard

The live wizard connects to the jpcite playground stream over SSE and renders each step progressively in section chunks; step 1 → step 2 → step 3 advance by button click.

Step 1 / recommended-program search

Enter a corporate number (13 digits) and a confirmation purpose. As an evidence check before handing long materials to an AI, it runs a search equivalent to GET /v1/intelligence/precomputed/query over SSE and returns recommended programs, citations, and Evidence-Packet metadata. By default source_tokens_basis=pdf_pages · source_pdf_pages=30 · input_token_price_jpy_per_1m=300 are filled in, so submitting returns source_url, source_fetched_at, known_gaps, and compression.input_context_reduction_rate. On the second try, change source_pdf_pages to see the difference; on the third, substitute your own question.

Step 2 / combination & exclusivity compatibility check

The recommended programs from step 1 are fed into an equivalent of /v1/compatibility/check, receiving exclusivity / combination rules and copy_paste_parts (200-character application-text templates) over SSE.

Step 3 / evidence-pack generation

Final packaging, equivalent to /v1/evidence/packets/query. Over SSE, work_queue / source_receipts / known_gaps arrive incrementally, and finally next returns the artifact URL. Output types include DD question sheet (30–60 questions), monthly watch registration, and deep program detail.

Tools you can call

ToolWhat it searches
search_programsProgram search (subsidies / loans / tax / certifications, 11,601)
search_casesCase studies (2,286)
search_loansLoans (108; collateral / personal-guarantee 3-axis)
search_lawsLaws (9,484 catalog / 6,493 full text)
search_tax_rulesTax rulesets (50)
check_enforcementEnforcement actions (1,185)

A 500 ms debounce means rapid clicks consume only one request. Each call returns the response highlights and response headers for inspection.

Connect from an AI agent

The live page detects connections from AI agents (e.g., Claude MCP) versus a normal browser. Add one line in Claude Desktop / Claude Code, etc., to use 261 MCP tools; you can continue beyond the anonymous quota with an API key.

Switch to continued use

An evidence pack whose structure you verified in the 3 steps can be run continuously at the scale of 100 or 1,000 companies. Pricing is fully metered at ¥3/billable unit tax exclusive (¥3.30 tax inclusive) — no tiers, no fixed monthly fee, stoppable anytime. Issue an API key on the pricing page.

This service is for information retrieval. Consult a qualified professional for individual, case-specific tax or legal determinations.

What comes back

jpcite returns a compact Evidence Packet or output artifact, not a final legal, tax, audit, credit, or application decision. Typical fields include source_url, source_fetched_at, corpus_snapshot_id, known_gaps, matched public records, professional-scope notes, and optional input-context estimates.
