Identity infrastructure for the agentic internet

What does AI know about you?How does it describe you to others?Make sure you wrote it.

The version of you AI works from was scraped, inferred, or written by a platform that benefits from owning the answer.

What's broken

LinkedIn closed its API to your agent

The data that represents you professionally is no longer machine-readable by tools you control.

Microsoft Entra is employer-issued

Platform-locked by design — the institution owns the credential, you get a viewing window.

The AI version of you wasn't written by you

The first reader is now a model with a 200k context window. The artefact it works from is a CV optimised for a recruiter's eyeballs.

Trust claims with no trail

A green checkmark with nothing behind it. No portable, verifiable evidence — just vibes.

A real AetherID, with its receipts

Same claim, different tier, depending on what backs it. The badge always says which.

What you're looking at

AetherID is the open, signed, agent-readable identity layer you write yourself — public for anyone (or anyone's AI) to read, and the same source your own AI tools work from. Every claim carries its receipts.

Same category as Sigstore (for software artifacts), Let's Encrypt (for domains), npm provenance (for package authorship) — applied to professional identity in the AI era.

How it shows up

Outward

Someone's AI is researching you

Cold outreach, recruiter brief, agent-to-agent intro. Your signed AetherID is what they read — not whatever LinkedIn happens to surface that day.

Inward

Your own AI tools work from you

Plug AetherID into Claude / Cursor / ChatGPT via MCP and your context is structured, signed, and identical across tools. Stop re-explaining yourself.

AetherID MCP server — the tools your AI gets:

list_lensesread_lensread_lens_markdowncreate_lensupdate_lensget_profile

RoadmapAgent-to-agent handshake— When my agent talks to yours, we exchange signed AetherIDs first. Discovery and trust before payload. Coming after v1.0-final.

What it isn't

Not a LinkedIn alternative.No network, no feed, no engagement loop. Structurally incompatible with engagement-economy mechanics.

Not a data broker.No profiles on people who haven't claimed and verified them. No scraping, no enrichment of non-users. Owner-pull only.

Not a bundled identity stack.Open protocol. Schema published. SDK open source. If AetherID-the-company fails, your W3C-anchored records keep working.
