Trial

Get a 14-day / 200-request trial API key with just an email address — no credit card, and no automatic conversion to paid use. The key is intended for integration checks before paid metered use.

Trial basics

The trial is intended for integration checks before paid metered use; no credit card is required.
Validity 14 days, request cap 200. One trial per email (lifetime); up to one issuance per IP per 24h; the magic link is valid for 24 hours.
Anonymous access remains limited to 3 requests per day per IP, while trial keys support a broader evaluation window.

Get the key

Enter your email on the Japanese trial page; a magic link arrives, and the trial API key is shown once at issuance. Copy it immediately — it cannot be displayed again once you close the screen.

Call it in 5 seconds (curl)

curl -H "Authorization: Bearer jc_..." \
  "https://api.jpcite.com/v1/programs/search?q=IT%20introduction%20subsidy"

Use it in Claude Desktop / Cursor / Cline (MCP config)

{
  "mcpServers": {
    "jpcite": {
      "command": "uvx",
      "args": ["autonomath-mcp"],
      "env": {"JPCITE_API_KEY": "jc_..."}
    }
  }
}

First run pip install autonomath-mcp or uv tool install autonomath-mcp (the legacy distribution name is kept for compatibility; the brand is jpcite). For the config-file location, see the Claude Desktop / Cursor / Cline guides.

Next steps

Getting started — minimal Python / Node examples, authentication, rate limits.
Claude Desktop (MCP) integration — use 261 MCP tools from an agent over stdio.

A "trial ending" email is sent when 3 days remain. Switch to production use from Pricing: first Checkout includes a one-time ¥800 API-key activation fee, then usage is ¥3/billable unit.

jpcite does not perform work falling under Certified Public Tax Accountant Act §52 / Attorney Act §72. jpcite is an evidence/output API that returns Japanese public bases as Evidence Packets / output artifacts; tax advice, legal consultation, filing on your behalf, and labor-and-social-security-attorney work are out of scope, and outputs do not replace confirmation by a licensed professional (tax accountant, attorney, sharoshi, administrative scrivener). See the Terms of Service for details.
