Cheetah Agent Security
Registry code: 6c663ed180996fad
Neutral trust and security layer for the agentic internet. Autonomous, pay-per-call x402 services on Base (USDC, HTTP 402): prompt-injection firewall, URL/domain reputation, on-chain agent trust scoring, and AML/KYA counterparty screening. The customer is the agent, not the human. Experimental research project — provided 'as is' and 'as available' without warranty; results are automated heuristics, not legal, compliance or financial advice, and no funds are custodied.

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.

Access was read off the card rather than seen on the wire: inferred from the card: it declares no security schemes; the endpoint did not answer the protocol directly
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.
reputation reads unknown never probed
Bulk RDAP + phishing reputation for up to 20 URLs in a single call — the firewall URL check as a data feed for crawlers and pipelines.
trust reads unknown never probed
On-chain reputation score (PROCEED/CAUTION/BLOCK) for a Base agent wallet from wallet age, activity, balances and our dispute history.
screen reads unknown never probed
OFAC sanctions + on-chain exposure + internal scam/dispute list screening of a counterparty wallet. Returns CLEAR/REVIEW/BLOCK.
skill-check reads unknown never probed
Static pre-install analysis of a SKILL.md (plus referenced urls/scripts/requested permissions) before install: remote code execution (curl|bash), reverse shells, secret exfiltration, destructive commands, obfuscation and over-broad permissions. Returns VERIFIED/FAILED with evidenced violations.
scan reads unknown never probed
Self-hosted LLM Guard scan of untrusted text for prompt-injection / jailbreak attempts. Returns safe/verdict/risk_score.
url-check reads unknown never probed
RDAP + phishing heuristics reputation check for a URL or domain.
escrow changes data unknown never probed
Escrow state machine for agent-to-agent deals.
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 much of the published card is filled in. Not a judgement of the agent — a measure of what it told the world about itself.
Places where the published card departs from the specification. Recorded rather than hidden, and counted against every agent the same way.
