Show HN: Travel Hacking Toolkit – Points search and trip planning with AI
I use points and miles for most of my travel. Every booking comes down to the same decision: use points or pay cash? To answer that, you need award availability across multiple programs, cash prices, your current balances, transfer partner ratios, and the math to compare them. I got tired of doing it manually across a dozen tabs. This toolkit teaches Claude Code and OpenCode how to do it. 7 skills (markdown files with API docs and curl examples) and 6 MCP servers (real-time tools the AI calls directly). It searches award flights across 25+ mileage programs (Seats.aero), compares cash prices (Google Flights, Skiplagged, Kiwi.com, Duffel), pulls your loyalty balances (AwardWallet), searches hotels (Trivago, LiteAPI, Airbnb, Booking.com), finds ferry routes across 33 countries, and looks up weird hidden gems near your destination (Atlas Obscura). Reference data is included: transfer partner ratios for Chase UR, Amex MR, Bilt, Capital One, and Citi TY. Point valuations sourced from TPG, Up

Tell HN: Anthropic no longer allowing Claude Code subscriptions to use OpenClaw
Received the following email from Anthropic: Hi, Starting April 4 at 12pm PT / 8pm BST, you’ll no longer be able to use your Claude subscription limits for third-party harnesses including OpenClaw. You can still use them with your Claude account, but they will require extra usage, a pay-as-you-go option billed separately from your subscription. Your subscription still covers all Claude products, including Claude Code and Claude Cowork. To keep using third-party harnesses with your Claude login, turn on extra usage for your account. This will be enforced April 4 starting with OpenClaw, but this policy applies to all third-party harnesses and will be rolled out to more shortly (read more). To make the transition easier, we’re offering a one-time credit for extra usage equal to your monthly subscription price. Redeem your credit by April 17. We’re also introducing discounts when you pre-purchase bundles of extra usage (up to 30%). We’ve been working to manage demand across the board, but

Show HN: Mtproto.zig – High-performance Telegram proxy with DPI evasion
Hey everyone. I built an MTProto proxy for Telegram aimed at bypassing active DPI censorship like the Russian TSPU. I chose Zig because it's perfect for writing fast network daemons and makes it incredibly easy to port low-level C bypass techniques like TCP desync and packet fragmentation. Would love to get some feedback or contributors! Comments URL: https://news.ycombinator.com/item?id=47632692 Points: 6 # Comments: 6
