_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • nft_metadata reads auth-required never probed

    Retrieve NFT collections, ownership, metadata, traits, and transfer history.

  • provision_endpoint moves money auth-required never probed

    Create a Quicknode subscription and RPC endpoint without human signup. Two-step flow: POST https://www.quicknode.com/api/v1/agent/subscriptions (pay via x402 or MPP; POST with no body to receive a 402 listing plans and payment methods), then POST https://api.quicknode.com/v0/endpoints with the returned QN_* key to create a dedicated RPC endpoint on any of 80+ chains.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
75%

How much of the published card is filled in. Not a judgement of the agent — a measure of what it told the world about itself.

spec deviations
5

Places where the published card departs from the specification. Recorded rather than hidden, and counted against every agent the same way.

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
