# Contact

Email is the fastest way to reach me. I read it myself and reply by hand.

- **Email**
  [coffee@aadhar.sh](mailto:coffee@aadhar.sh)
- **Coffee in NYC**
  [aadhar.sh/coffee](https://aadhar.sh/coffee)
- **Security reports**
  [/.well-known/security.txt](https://aadhar.sh/.well-known/security.txt)
- **The crawler**
  [/bot](https://aadhar.sh/bot)

## Grab a coffee

If you're in New York and want to talk, pick a slot at [/coffee](https://aadhar.sh/coffee) or write to [coffee@aadhar.sh](mailto:coffee@aadhar.sh). Each booking is a manual opt-in on my side, so I confirm it by hand. Open slots are also published as JSON at [/coffee/availability.json](https://aadhar.sh/coffee/availability.json).

## Report a security issue

The disclosure contacts and scope are in [/.well-known/security.txt](https://aadhar.sh/.well-known/security.txt) (RFC 9116), and [/security](https://aadhar.sh/security) describes the headers and policies this site sends. Please write before you publish anything.

## If my crawler visited you

AadharshBot is this site's crawler. [/bot](https://aadhar.sh/bot) explains what it fetches, how to verify its signatures, and the one `robots.txt` line that stops it. Questions or complaints about it go to the same address, [coffee@aadhar.sh](mailto:coffee@aadhar.sh).

## Elsewhere

I'm [@oddhash](https://x.com/oddhash) on X, and on [LinkedIn](https://www.linkedin.com/in/aadharsh-pannirselvam), [GitHub](https://github.com/oddharsh) and [Farcaster](https://farcaster.xyz/aadharsh). [/about](https://aadhar.sh/about) has the rest.
