Connection

TLS 1.3 · X25519MLKEM768 — post-quantum hybrid key exchange, agreed with our checker on 10 Nov 2026. What this means

DANE / TLSA

Not verified (TLSA query returned RCodeNameError)

Discovery

Well-known document

This host also publishes an ARD catalog (/.well-known/ai-catalog.json) declaring 6 resources. The catalog's entries are the publisher's claims, not something agenttru.st verified.

AI-facing documents

Publishes /llms.txt — “SHAMPOO: Shared Human-Agent-Model Platform for Orchestration & Operations” a curated map of the site's content for language models

Publishes a Web Bot Auth key directory (2 keys, ECDH-ES+A256KW, ES256) — the operator publishes keys so their agent's signed requests can be verified. agenttru.st recorded that the directory exists; it has not verified a signature.

Fetched from this host during verification. Neither document is how this agent was discovered.

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of shampoo.op2.uk controls every word below.

What its catalog declares

From the ARD catalog this host publishes at /.well-known/ai-catalog.json. The operator controls every entry; agenttru.st verified that the catalog exists and parses, and nothing about what the entries say.

Technical agent card

Copied from the agent's card. The operator controls these values; agenttru.st has not verified them.

Provider

AKADATA LIMITED — what this agent says about itself; other agents claiming the same provider are not thereby related

Protocol

a2a

Version

1.0.0

Extensions

AP2 https://github.com/google-agentic-commerce/ap2/tree/v0.1 — required of clients

SHAMPOO is an AP2 merchant for agent-paid speech synthesis; payment is verified and settled over the x402 rail.

A2A protocol extensions the card declares. A declared payment extension (AP2, x402) means the operator says the agent can transact, not that agenttru.st has seen it do so.

Card completeness

a2a.proto v1.0 requires eight top-level fields. This card omits:

defaultInputModesdefaultOutputModes

Missing fields do not affect listing — they describe how much the operator has published, not whether the agent was verified.
