100 ★ stars. The tech is great. The start is humble. Thank you early supporters!

We're at the YC Resend DevTools meetup and they are talking about auth for agents.

Almost 300 agents have created identities and generated/rotated almost 400 public keys now on vestauth's platform.

there is probably a future where an agent can carry multiple 'identities' - oauth tokens, api keys, username and passwords. but all of these are weak. signed http requests are strong and it should be the future we adopt in the industry for agents.

Who's going to be the first x402 payment provider accepting vestauth logins instead of API keys?

Automatic token rotation as a side effect is such a win for the industry.

Our ecosystem is taking shape. Soon we will have everything in place to pay new providers to build agent tools using vestauth identities.
Yesterday added both a filesystem and simple email system to @vestauthx. Today working on a metering system. Will start with payments and then add additional reputation, ip, and network layers.

Making progress. With vestauth you can quickly add tools for your agents.
Wrapped up the simple file system (SFS) for @vestauthx. It has tons of constraints on purpose. Only one level deep at the moment. Just /filepath. Just one filetype at the moment. Just /*.md Cap on filesize. Just 1mb Constraints are often good! Try it out for yourself: ``` $ curl -sSf vestauth.sh | sh $ vestauth agent init $ vestauth agent curl sfs.vestauth.com/write -d '{"filepath":"/hello.md","content": "hello world"}' $ vestauth agent curl sfs.vestauth.com/list vestauth agent curl sfs.vestauth.com/read -d '{"filepath":"/hello.md"}' ``` The future is small sharp tools combined with simple agent identity. Try vestauth, its tools, and build your own tools! Next up, we'll be adding an email tool - so that vestauth agents can send email.

Great!

This was so easy to add. Looking to add VestAuth to more of my tools.

Just added the first 3rd-party tool: Docle by @dantelex. Agents now verify an email address before sending it. No more blind sends.

Why self-host Vestauth? Vestauth works great with the default hosted infrastructure, but there are good reasons to run your own: Control your infrastructure: keep registration, discovery, and key serving under your domain. Compliance / data residency: run on your own cloud, region, or network boundaries. Custom operations: use your own Postgres, observability, backups, and deployment pipeline. Private environments: support internal agents and internal tools. Future flexibility: customize trust rules, federation, and deployment topology as your agent ecosystem grows. vestauth.com/blog/2026/02/25…

We purchased the domain botauth.ai and we will be making generation of web-bot-auth headers extremely easy there. ala auth's jwt.io.
