A flare gun for the social and agentic web

Where is
anyone?

Look up a handle. Get the location they most recently chose to share—never an inferred one.

How it works

Post once.
Be findable anywhere.

  1. 01

    Send a flare

    Mention @whereis.co on Bluesky with a location, such as @whereis.co Lisbon #whereis. Be as exact or vague as you want.

  2. 02

    We publish your endpoint

    Your permanent page and JSON endpoint update. There is no account, app, or location permission.

  3. 03

    Share the signal

    Put it in a bio, email footer, travel page, or give the API to an agent. Your original post stays attached as proof.

Usage guide

Send a flare.
Keep the URL.

Updates come from the Bluesky identity they describe. The resulting page works for people, scripts, and agents—with no WhereIs account or API key.

For people

Update from Bluesky

01

Post your location

@whereis.co Sydney, Australia

Mention @whereis.co from your own account. Exact, broad, and playful locations are all valid.

02

Use your permanent link

https://whereis.co/your.handle

The bot replies with this URL within about five minutes. Share it once; it stays the same.

03

Update—or clear—it

Post a new mention to replace the current location. To remove your signal, post:

@whereis.co #whereis-off

For agents and apps

Read the public API

Use the handle without a leading @. Reads are public, CORS-enabled, and require no API key.

Terminal
curl https://whereis.co/api/v1/location/cje.io

200Current self-declared signal, source, timestamp, and age.

404Unknown, empty, or opted-out handle with found: false.

For agents, apps, and curious humans

One obvious endpoint.

GET https://whereis.co/api/v1/location/alice.example

{
  "found": true,
  "handle": "alice.example",
  "location": "Lisbon for the week",
  "publishedAt": "…",
  "sourceUrl": "https://bsky.app/…",
  "ageSeconds": 64
}

The boundary matters

WhereIs.co says what people said—not where devices are.

No GPS collection. No IP geolocation. No background tracking. No third-party claims. A person can post #whereis-off to clear their signal.
