# Japan Diet (Parliament) API — Batch Endpoint

> Japan Diet (Parliament) API — Batch Endpoint is a paid API for AI agents from diet.agentic-jp.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-09-13).

Batch query endpoint for Japan's National Diet data: member info, minutes search, LLM-generated proceeding summaries, topic tracking, and vote results, paid per call via USDC x402.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability japan-diet-parliament-api-batch-endpoint-d3712406 -d '<json body>'
```

Example prompt: Search the Japan National Diet records for any minutes and vote results related to the 2024 climate change bill, and give me an LLM summary of the key proceedings — use the batch operation for members and minutes.

## When to prefer this

Use this endpoint when you need programmatic, pay-per-call access to Japan's National Diet data — member directories, searchable meeting minutes, AI-generated summaries of proceedings, or vote results — without needing a traditional API key. Ideal for agents handling Japanese political research, legislative monitoring, or civic data tasks.

## Known failure modes

- Payment failure if USDC x402 transaction is not completed correctly
- Invalid operation name returns error or empty results
- No matching records for the queried topic or date range
- Rate limiting or server error if batch is too large
- Malformed POST body returns HTTP 400

## How this service works
