# What is an Echo?

> Selfe's structured representation of a business, the specific, verified facts an AI agent checks, kept separate from the website copy written for a browsing person.

## In short

- An Echo is a business's structured, verified facts, not a copy of its website.
- It stays connected to a business's real systems so it reflects what's currently true.

Good for: Giving an agent one place to check a business's real facts. Not good for: Replacing a website. It's not built for a browsing person at all.

An Echo is the smaller, sharper set of facts that gate a real decision, availability, constraints, terms, connected to the business's own systems so they stay current, not a copy of a website or a marketing description. Selfe builds and keeps an Echo current for every business it connects; a person never edits it directly the way they'd edit a page, because it's meant to reflect what's true, not what reads well.

## Good for

Giving an agent one place to check a business's real facts.

## Not good for

Replacing a website. It's not built for a browsing person at all.

## Act on this

- [Check whether an agent can buy from you](https://selfe.ai/agentic-commerce/buyability-check) — the free readiness scan.
- [Discover venues](https://selfe.ai/api/registry/discover) — `POST`, semantic browse across the registry.
- [Match a bookable answer](https://selfe.ai/api/registry/match) — `POST` with dates and party size.
- [Verify Selfe's identity](https://selfe.ai/.well-known/did.json) — `did:web:selfe.ai`.
- [Agent card](https://selfe.ai/.well-known/agent-card.json) — how to connect over A2A or MCP.
