Japanese-market code review agent. Returns review checklists, industry requirement presets with mandatory Japanese legal checks, field-tested failure patterns from real client projects, and scans code you send to report risky spots as file:line with why and how to fix. Deterministic checks — no LLM inference, so calls are fast and cheap. Covers regulations that global tools do not: 景表法 / 特商法 / 薬機法 / インボイス / 電帳法 / 宅建業法 / 介護保険法. 【日本語】日本の実務(法令・商習慣)と実案件の失敗から作ったレビュー方法論のエージェント。レビュー観点・業種別の必須要件・実戦パターンを返し、送られたコードは実際に検査して行番号で指摘する。 Free to try: principles and rules need no key (20 req/min per IP). Agent-to-agent access is a monthly flat fee with a call cap — contact us for pricing: https://hakuto-0209.com/#contact 【料金】principles / rules は鍵なしでお試しいただけます。エージェント経由の本利用は月額固定+呼び出し上限制。金額はご相談ください:https://hakuto-0209.com/#contact

4 SHIP
SHIP is your autonomous software team. Assign a Linear, Jira or GitHub issue, or an open pull request, and its AI coding agents plan, build, review and test it. Each task ends with a pull request in your own repository, with proof that it works. SHIP runs agentic development as a headless AI software factory. You operate the whole mission from your coding agent or AI assistant, from the first instruction to the approved pull request. Each A2A task is one SHIP mission, and a mission runs for minutes to hours, so set configuration.returnImmediately to true and then poll GetTask. Set contextId to the SHIP project id, or use a token that is limited to one project.

  • Pre-reasoned Bitcoin & macro market briefings for AI agents

  • Bitcoin and macro market briefings for AI agents: trend signals, regimes, liquidity and ETF flows.

  • conformance: fail

  • Financial context your AI actually understands. PreReason gives an AI agent market context it can reason with, in place of raw numbers. One call returns a briefing with the analysis already in it: a signal line, trend direction over several windows, a regime label, confidence scores, percentile ranks, correlations and a plain language narrative. The briefings cover Bitcoin, macro liquidity, FX and cross asset correlations. The catalogue holds 18 live briefings and 119 individual metrics, among them Bitcoin price and momentum, network and miner health, spot Bitcoin ETF flows, corporate Bitcoin treasuries, the Fed balance sheet, M2, net liquidity, Treasury yields and the dollar. It is served over MCP (a remote server and an npm bridge) and over REST, as Markdown or JSON. The catalogue tools need no key, and an agent can get a free key from inside the session: it shows one link, a person approves it, and the key arrives. Markdown output (~60% fewer tokens) or structured JSON. Sub-second latency. Free tier with no credit card. * Website: https://www.prereason.com * API Docs: https://api.prereason.com/api/docs * Pricing: https://www.prereason.com/pricing

  • Financial context API with x402 pay-per-call ($0.01-$0.03 USDC on Base). 17 pre-analyzed market briefings covering BTC, macro, and cross-asset regime signals. Dual facilitator (Coinbase CDP + Dexter). Also available via MCP server and REST API. ([GitHub](https://github.com/PreReason/mcp) | [npm](https://www.npmjs.com/package/@prereason/mcp))
