Each id links to the agent's token on Blockscout. "-" means not declared, or not an x402 seller.

How we checked

We read the ERC-8004 identity registry on Robinhood Chain at block 100007973: for each of the 20,046 agent ids, its token URI, owner and agent wallet. Every read was read-only; nothing was signed, paid or sent.

Each registration card was fetched once. Each endpoint a card declares was asked once: MCP with one initialize call, x402 with one GET, websites with one GET.
An MCP server counts as answering when initialize returns a valid result. An x402 endpoint counts when it answers HTTP 402 with payment terms (who is paid, in which asset).
BV-7X limits requests to 30 a minute. Every endpoint that answered HTTP 429 (rate limited) was asked again at that pace until it answered; none is still unread, so every row carries its final result.
"Wallet sent a tx" is the transaction count of the agent wallet (else the owner). A wallet that is a smart contract can have done more than its count shows.

What each class means

real service: At least one MCP server or x402 endpoint answered.
site only: Only a website or other link answered.
card only: The card loads and parses, but nothing it declares answered (or it declares nothing).
broken card: The token URI is empty, not a link, could not be fetched, or is not JSON.

A broken card does not mean bad intent. A host can go offline, a project can move, or a card can be registered before it is published. Each row is what one read on 2026-10-28 returned, nothing more. Information only, not financial advice.
