## Unverified actions

Read from the page's own content, with the wording each was drawn from. Inference is kept separate from tested facts; an agent completing the action is tier 3.

- **search** — "https://value.us/{domain} - retailer hub: all verified facts for one store" → `https://value.us/{domain}`
- **query_api** — "MCP server: https://value.us/mcp (Streamable HTTP JSON-RPC, no auth)" → `https://value.us/mcp`

## Context

351 sites in this index share the type "directory"; 188 are transactional.

## How we grade

- tier 1 — **Declared**: The site says agents are welcome in its robots.txt. A permission, not a capability.
- tier 2 — **Probe-verified** (this site): We fetched the site and tested each signal ourselves. Dated, repeatable, re-checked on a schedule.
- tier 3 — **Behaviourally verified**: An agent completed the action end to end — booked, bought, submitted — and it worked.
