24 alternatives to A2A agent to verify information counter party's credentials
This agent asynchronously sends out a verification link to the user, and updates the context via a push notification when the user completes verification. An example usecase is, when the a recruiter is sifting through multiple resumes and needs to verify that the candidate actually works at the place they claim to work or any other information - they can invoke this verification A2A Server. The this agent will then figure out what should be the link that should be sent to the user. Once the user completes the verification using that link, the recruiter's context is updated with a status…

A2A Registry▲14The implementation is purely static, agents are added via PRs, and updates are made via CI. Probably not scalable, but more than enough for the 1 agent thats there now. Any one know if there are other A2A agents in the wild that I can index here?

A2A Protocol▲109Hi HN, I am an independent open-source researcher. For the past few months, I've been building a2a-project, an experimental economic layer for autonomous AI agents on the Base Mainnet. The Problem: AI evolution is exponential, while human regulation is linear. If agents become economic actors, they will transact at speeds and granularities that traditional fiat rails cannot handle. We need a native protocol to bridge this "Speed Gap" and ensure stability. The Experiment (Quantum-Humanistic Economics): I implemented a novel mechanism into Solidity smart contracts: Quantum Task Buffer: Work…

relaydfree tier, from $5/mo▲101I kept missing when my Codex agents finished, so I built relayd — a mobile dashboard that sends push notifications and lets me continue agents from my phone. Free tier available. Would love feedback.

Much of my work right now involves complex, long-running, multi-agentic teams of agents. I kept running into the same problem: “How do I keep these guys in line?” Rules weren’t cutting it, and we needed a scalable, agentic-native STANDARD I could count on. There wasn’t one. So I built one. Here are two open-source protocols that extend A2A, granting AI agents behavioral contracts and runtime integrity monitoring: - Agent Alignment Protocol (AAP): What an agent can do / has done. - Agent Integrity Protocol (AIP): What an agent is thinking about doing / is allowed to do. The problem:…

We were building an agent system and wanted email as a trigger. We decided to take it out and made it a standalone service. The primary email features we wanted and used for our own agent system: 1. Email threading stays consistent with agent conversation threading 2. Human in the loop review for outbound emails (especially during testing phase) 3. Quick onboarding/offboarding email addresses for agents within minutes 4. Websocket for local agents and at-least-once webhook delivery for Cloud agents Not yet: DMARC (only SPF/DKIM today), scoped API keys, HA/multi-region (single…

We now write most of our code with agents. For a while, PRs piled up, causing review fatigue, and we had this sinking feeling that standards were slipping. Consistency is tough at this volume. I’m sharing the solution we found, which has become our main product. Continue (https://docs.continue.dev) runs AI checks on every PR. Each check is a source-controlled markdown file in `.continue/checks/` that shows up as a GitHub status check. They run as full agents, not just reading the diff, but able to read/write files, run bash commands, and use a browser. If it finds…

I kept copy pasting between two Claude Code instances. My teammate would ask me something about a module I wrote, I'd paste their question into my Claude Code, copy the answer, send it back on Slack. We were playing telephone between two agents that could have just talked directly. So I built AgentDM. It's a hosted messaging grid where AI agents DM each other by @alias. Any MCP compatible client connects with a 5 line JSON config no SDK, no shared runtime. This is how it works: - Each agent gets a unique @alias. - Three(main) MCP tools: send_message, read_messages, message_status. - Messages…

Hi HN! I run a few Claude Code sessions in parallel and kept cmd-tabbing around just to find out one of them had been sitting on a permission prompt for ten minutes. There's a hardware gadget I liked (called SidePulse.io) so before waiting to get my shipment I built the software version instead :D I hope you like it and find it useful as I do!
