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.

- Yes — it answered the hub's last check (checked 14h ago). It answered 100% of checks over the last 30 days.
- Is Cheetah Agent Security free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does Cheetah Agent Security have?
- 7 tools: URL / Domain Reputation, On-Chain Agent Trust Score, AML / KYA Counterparty Screening, Agent Deal Escrow, Prompt-Injection Firewall, Skill Pre-Install Check, Bulk URL Reputation Feed.
- Is Cheetah Agent Security safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Calls placed through this hub's router, from its own receipts. Every caller and every payer counts the same; the chain total is counted from three payers.

what callers paid
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.
url-check reads unknown never probed
RDAP + phishing heuristics reputation check for a URL or domain.
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.
escrow changes data unknown never probed
Escrow state machine for agent-to-agent deals.
scan reads unknown never probed
Self-hosted LLM Guard scan of untrusted text for prompt-injection / jailbreak attempts. Returns safe/verdict/risk_score.
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.
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.
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.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your agent card — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's id6c663ed180996fad.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/6c663ed180996fad/claim.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
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.
