I believe in a future where agents handle most of everyday transactions by interacting directly with one another.

I was keeping track of agent payment related protocols and work thats happening, i was reminded of the xkcd#927.

I built this so AI can keep track of it for me.

Completly AI generated and maintaind.

Possible attack surface - prompt injection on news websites, github issues, x.

¯\_(ツ)_/¯

You can.

Everyone will have their own versions of the rest endpoints, their own version of input params, and lots and lots of docs scatterd.

A standard, will help the ecosystem grow. Tooling, libraries etc.

While I am not familiar with OPs project,

I can somewhat answer this to best of my knowledge.

Right now, businesses communicate with REST Apis.

That is why we have API gateways like AWS Gateway, Apigee, WSO2 (company i used to work in), Kong, etc so businesses can securly deploy and expose APIS.

As LLMS gets better, the idea is we will evenutally move to a world where ai agents do most of business tasks. And businesses will want to expose ai agents instead of APIS.

This is where protocols like a2a comes in. Google partnering with some other giants introduced a2a protocol a while ago, it is now under linux foundation.

It is a standard for one agent to talk to another agent regardless of the framework (langchain, crewai etc) that is used to build the agent.

https://a2a-protocol.org/latest/ is the best place to start.
Good to see a2a getting more attention.

If you are a rustacean, We are building something in the a2a space as well. Tho we don't have sudden increase in stars :/

We (me and my co-founder) have been working on this library for a while and would love to get your thoughts.github.com/agents-sh/radkitradkit.rs/getting-started/Most of the agent librararies out there just adds a huge prompt, put all the tool definitions and call the LLM on a loop hope and for the best.This is not a way to build reliable ai agents. A better way to build ai agents is described...

It was a gmail, and i cannot find this largest technology website nowhere in google search.

Now that i say this out loud, i think you are probably right.

I didn't want this post to come across as promotion, hence why i didn't post it on my initial comment.

Hey HN,

I recently launched something I had been working on. And I have setup an auto email asking for user feedback. And I relieved this email.

I find this inquiry bit strange. So I ask you, is this normal?

Hey HN,I've been a long time lurker of this site, and nothing i've built before felt "worthy" enough to share here. This one came pretty close. So here we go.I've been playing around with the idea of "ai agent" collaboration. With protocols like MCP and A2A coming out, I think this is an interesting area to work on.So I built, Microagents.The idea is very simple.1)Connect your tools (Gmail,...
