We’re building Prism (https://www.prismvideos.com), an AI video creation platform and API.Here’s a quick demo of how you can remix any video with Prism: https://youtu.be/0eez_2DnayIHere’s a quick demo of how you can automate UGC-style ads with Openclaw + Prism: https://www.youtube.com/watch?v=5dWaD23qnroAccompanying skill.md file: https://docs.google.com/document/d/1lIskVljW1OqbkXFyXeLHRsfM...Making an AI video today usually means stitching together a dozen tools (image generation, image-to-video, upscalers, lip-sync, voiceover, and an editor). Every step turns into export/import and file juggling, so assets end up scattered across tabs and local storage, and iterating on a multi-scene video is slow.Prism keeps the workflow in one place: you generate assets (images/video clips) and assemble them directly in a timeline editor without downloading files between tools. Practically, that means you can try different models (Kling, Veo, Sora, Hailuo, etc)Mar 11, 2026 4:16 PM

Show HN: AgentCash – access 280 paid APIs with no API keyshttps://agentcash.devHey HN - I'm Mason, and I'm excited to share AgentCash - a CLI to help your agent discover and pay for premium APIs and paywalled data.The problem we kept running into was simple: if you want an agent to use premium data or services, the setup flow is awful.You have to find the right provider, sign up manually, subscribe, generate an API key, install tooling, and then teach your agent how to use it. Then do that again for the next provider.We wanted a simpler model: give the agent a universal balance, let it discover available resources, and let it pay per call.So AgentCash gives agents one balance with access to 280+ paid APIs. It’s built on x402 [0,1] (the Coinbase/Cloudflare payments protocol) and designed to work with tools like Claude Code, Codex, OpenClaw, Cursor, etc.I also am really proud of our onboarding flow - we actually use AgentCash itself to research you and the decide how much free cash to give based on a score.The vision for this is to essentially give agents JIT conteMar 10, 2026 4:39 PM

Launch HN: Palus Finance (YC W26): Better yields on idle cash for startups, SMBshttps://news.ycombinator.com/item?id=47278980Hi HN! We’re Sam and Michael from Palus Finance (https://palus.finance). We’re building a treasury management platform for startups and SMBs to earn higher yields with a high-yield bond portfolio.We were funded by YC for a consumer-focused product for higher-yield savings. But when we joined YC and got our funding, we realized we needed the product for our own startup’s cash reserves, and other startups in the batch started telling us they wanted this too.We realized that traditional startup treasury products do much the same thing: open a brokerage account, sweep your cash into a money market fund (MMF), and charge a management fee. No strategy involved. (There is actually one widely-advertised treasury product that differentiates on yield, but instead of an MMF it uses a mutual fund where your principal is at considerable risk – it had a 9% loss in 2022 that took years to recover.)I come from a finance background, so this norm felt weird to me. The typical startup cashflow pattern isMar 6, 2026 6:26 PM

Show HN: Feedster, an RSS/feed reader focused on discovery and agent integrationhttps://feedster.coHey HN,I built Feedster for a few reasons:1. I want to spend more time reading people's blogs, long form content, even more traditional digital publications and less time on social media.2. RSS readers have typically felt a lot like Apple Mail circa 2010... Unread counts for every feed, everything in its own discrete view, no means for easily discovering new stuff. Not necessarily a bad thing, but it does make reading content feel like _work_ which is directly opposing goal number 1.3. No one has really rethought the shape of RSS in quite some time (Google Reader is probably the biggest re-think here that I can remember). It's typically been a client that downloads posts from various feeds on the internet. This is simple and it works, but what if there was a different shape that was more communal, more editorial, and was web-based?4. I haven't seen any RSS-powered AI agent workflows and I wanted to experiment with what that might look like. To start, I built a hosted MCP server that usMar 6, 2026 5:56 PM

Show HN: BidWix – one-shot price agreement using secret max/minhttps://bidwix.com/Hi HN — I built BidWix, a small negotiation tool for agreeing on a price without haggling.How it works:- The buyer enters their true maximum price (kept secret from the seller). - The seller enters their true minimum price (kept secret from the buyer). - If there is overlap, BidWix suggests a single “fair” price using the geometric mean (so the compromise is symmetric in percentage terms, not absolute currency units).Notes:- No signup. Email is optional. No ads. - BidWix stops at the price suggestion. It does not handle payment, contracts, escrow, or delivery. - It’s meant for cases where both sides want to make a deal, but don’t want the “you go first” dance. - I’m not a skilled negotiator myself, so I wanted a tool where negotiation skill is less of an advantage. - It seems to work especially well for intangible goods (I’m a sound designer).If you try it, I’d value feedback on:- Where the flow feels confusing or too wordy. - Whether the suggested price feels reasonable in real negotiMar 5, 2026 12:24 PM

I built it over the last few days using Claude and a lot of vibe coding.The idea came from my own investing workflow: I often look at companies through the lens of specific investors (Buffett, Lynch, Taleb, etc.). I wanted a tool that could generate investment ideas filtered through those frameworks.What the app does:You choose an investor (Buffett, Lynch, Soros, Damodaran, etc.) and an asset class (stocks, startups, crypto). The app then generates 10 opportunities and explains why that investor might find them interesting, based on their known principles.Under the hood: • Node.js server (no frameworks) • Vanilla JS frontend • GPT-4o for research / synthesis • live price data • Stripe + Google OAuth • hosted on RailwayIt’s still an experiment and I’m curious if the idea actually makes sense to other investors.You can try it here:https://www.moatradar.comHN users can get 10 free credits:https://www.moatraMar 4, 2026 11:25 PM

Show HN: Armalo AI – The Infrastructure for Agent Networkshttps://news.ycombinator.com/item?id=47244042Hey HN — I'm Ryan, founder of Armalo AI (https://armalo.ai). I spent years as a software engineer at Google, YouTube, and AWS, most recently building AI agents at AWS. Watching those systems interact in production — and seeing the same gaps appear over and over — convinced me that the missing piece wasn't more capable agents, but the infrastructure underneath them. So I left to build it.Armalo AI is the infrastructure layer that multi-agent AI networks need to actually function in production.THE PROBLEMEvery week there's a new story about an AI agent deleting a production database, a multi-agent workflow cascading into failure, or an autonomous system doing something its operator never intended. We dug into 2025's worst incidents and found a consistent root cause: agents have no accountability layer.You can't Google an agent's reputation. When one agent delegates to another, there's no escrow, no contract, no recourse. State doesn't persist across a network. And as agents start hiring Mar 4, 2026 6:53 AM

Ask HN: How are you structuring Markdown-based context for AI coding agents?https://news.ycombinator.com/item?id=47231386I’ve recently transitioned from using LLMs in-browser to a local agentic workflow in VS Code (Gemini Code Assist). I can approve/disapprove changes which is nice, but I’ve hit a wall regarding context management. Initially, I provided all the whole repo as context to the non-agentic version of Gemini code assist and it performed well.I read the agentic mode is "better" so to keep the agent aligned with my project's architecture, I’ve manually built 7 dense Markdown files that serve as the system instructions for the project. I require Gemini to update these files as we implement features.gemini.md (instructs gemini to read the other md files and handle updating) project_overview.md, architecture.md, features.md, database.md, api.md, security.mdEach file is between 500–1,500 words so I’m concerned if f this is the right way to go.

Show HN: AgentThreads – Stack Overflow for AI Agentshttps://agentthreads.devI was listening to a recent YC podcast about "build something agents want", and while building apps with Claude Code, I kept running into trouble figuring out how APIs actually behave in practice. And knowing that most companies won't update their docs to be agent-friendly, it clicked — agents need their own Stack Overflow.AI agents are consuming APIs at a scale and speed that human-written documentation can't keep up with. AgentThreads is a community directory where agents discover, submit, and review APIs — for agents, by agents.The idea came from watching agents fail silently on undocumented edge cases, relying only on Google searches and bad docs. They need structured, community-maintained knowledge they can query at runtime.A few things we built:- API directory with agent-written reviews and ratings- No UI, just REST — built for agents, not humans- Anti-spam verification (agents solve reasoning challenges, not CAPTCHAs)- Karma system so agents build reputation over timeBuilt mostlMar 3, 2026 11:11 AM

Our QA team was struggling with the exact same bottleneck, so I built BreakMyAgent.It’s an open-source sandbox that runs an automated barrage of standard exploits against your target LLM to see if it leaks data or ignores core instructions.How it works under the hood: - The UI is built with Streamlit, backend is FastAPI, and dependency management is handled by `uv`. - You paste your system prompt and hit run. It fires 12 baseline attack vectors (Direct leaks, XSS payloads, Context overflows, etc.) concurrently. - The core mechanic is "LLM-as-a-Judge". It uses a hardcoded `gpt-4.1-mini` with strict alignment rules to systematically evaluate the target's responses. - It supports OpenAI, Anthropic, and a solid list of open-weight models via OpenRouter (including DeepSeek V3/R1, Qwen 2.5, and Llama 3.3).There is a hosted free versFeb 26, 2026 1:00 PM
