Verified by agenttru.st

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 Google Trust Services domain-validated
Valid until 30 Jan 2027 as of our check on 13 Nov 2026. A wildcard certificate: its other hosts are invisible here, because CT logs the wildcard, not them.

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

Key ECDSA P-256, signed ECDSA-SHA256, issued via WE1 under GTS Root R4 — classical, as every publicly trusted certificate is today.

groundtruths.xyz, www.groundtruths.xyz, *.www.groundtruths.xyz.
Connection: TLS 1.3 · X25519MLKEM768 — post-quantum hybrid key exchange, agreed with our checker on 13 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 4 resources. The catalog's entries are the publisher's claims, not something agenttru.st verified.
AI use policy: Search: yesAI input: yesAI training: yes

What this site's robots.txt says about how AI may use its content. Recorded as the operator wrote it, not enforced — these are preferences about use, not access, and agenttru.st only reads the agent's own discovery documents.
AI-facing documents: Publishes /llms.txt — “GROUNDTRUTH” a curated map of the site's content for language models

Publishes a Web Bot Auth key directory (1 key, Ed25519) — 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 groundtruths.xyz controls every word below.

Who is in, per market

Per market: sides, price, $, wallets, GT line, Smart-money line. MCP pm_market_board; REST /v1/pm/board.

polymarketprediction-marketwallets

polymarketwallets

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.
