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 23 Jan 2027 as of our check on 12 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.

Names on this certificate (3)

email-validation.org, api-eu.email-validation.org, *.api-eu.email-validation.org.
Connection: TLS 1.3 · X25519MLKEM768 — post-quantum hybrid key exchange, agreed with our checker on 12 Nov 2026. What this means
DANE / TLSA: Not verified
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 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 — “email-validation.org” a curated map of the site's content for language models

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 email-validation.org controls every word below.

Validate an email address

Checks one email address and returns the result as a data part: status (valid, invalid, catch_all, unknown or disposable), reason, recommended action (send, send_with_caution, remove or retry_later) and details such as catch-all, disposable and role flags, plus a one-line text summary. Send one address per message, in a text part or in a data part {"email": "…", "ip_address": "…", "timeout": 5-15}. Uses 1 credit; unknown results are free, and so are errors. Test addresses <reason>@sandbox.email-validation.org are free.

Examples it gives

Is jane@example.com a valid email address?
{"email": "accepted@sandbox.email-validation.org"}
{"email": "catch_all@sandbox.email-validation.org", "timeout": 5}

Get the credit balance

Returns the credit balance of the account that owns the API key, any debt, credits still being applied and the credit lots with their expiry dates, as a data part plus a text summary. Free. Ask in a text part (for example "How many credits do I have left?") or send metadata {"skill": "get_credits"}.

Examples it gives

How many credits do I have left?
{"skill": "get_credits"}

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.
