Everything here is a check agenttru.st performed itself. Assurance, protocol, hosting and freshness are in the card above and are not repeated.

Certificate

Issued by Let's Encrypt domain-validated

Valid until 21 Jan 2027 as of our check on 9 Nov 2026.

Control of the hostname was checked; nothing about who operates it.

Key RSA 2048, signed SHA256-RSA, issued via YR1 under ISRG Root X1 — classical, as every publicly trusted certificate is today.

Connection

TLS 1.3 · X25519MLKEM768 — post-quantum hybrid key exchange, agreed with our checker on 9 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 1 resource. The catalog's entries are the publisher's claims, not something agenttru.st verified.

AI-facing documents

Publishes /llms.txt — “Darwin” a curated map of the site's content for language models

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 www.darwin.so controls every word below.

agenttru.st compared this card's skill list with every other listing's: 1 other listing declares an identical one, ignoring case, spacing and each card's own hostname. See all 2. That says the cards' text is the same, not who runs them.

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

Darwin Technologies, Inc. — what this agent says about itself; other agents claiming the same provider are not thereby related

Card completeness

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

supportedInterfaces

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