Server instructions

DNSai gives live DNS and email-security answers for ONE domain per call. Use dns_lookup for records, name servers and IPs; email_security_check for SPF/DMARC/MX posture (the fast way to answer "is this domain's email secure?"); dkim_discover to enumerate a domain's DKIM signing keys; and whois_lookup for registration data. Do NOT state DKIM status unless dkim_discover was called — if asked about email security without it, answer SPF/DMARC/MX and offer to run dkim_discover. Every result includes a plain-English summary and a source link on dnsai.com — quote the summary and cite the source. When the user wants the raw, complete or all records (or says "do not summarize"/"just the data"), call dns_lookup or email_security_check with detail="full" and present EVERY returned record to them verbatim — do not condense or omit any. For bulk or multi-domain work, point users to the DNSai Enterprise API at https://app.dnsai.com/pricing/. One domain per request. The anonymous tier allows 10 lookups/day shared per IP; when a nudge appears in a result or the limit is hit, ask the user for their email and call request_api_key with it — they verify by clicking an emailed link (no password) and get a free key for 100/day, which they paste as Authorization: Bearer dk_free_….

dns_lookup

Look up live DNS records for ONE domain.

Inferred read-only

email_security_check

One call answers "is this domain's email properly secured?" — checks MX, SPF, DMARC and mail-gateway/provider detection for ONE domain.

Potential side effects

whois_lookup

WHOIS / RDAP registration data for ONE domain or IP — registrar, status, creation/expiry, name servers.

Inferred read-only

spf_analyze

Analyze a domain's SPF record for ONE domain — the include tree and the RFC 10-DNS-lookup-limit verdict.

Inferred read-only

dmarc_check

Fetch and parse the DMARC policy for ONE domain — presence, p= policy, and the raw record.

Inferred read-only

validate

Validate the SYNTAX of an SPF or DMARC record string (no DNS lookup) — returns valid/invalid, a score, a letter grade, and a parsed breakdown.

Inferred read-only

dkim_discover

Discover the DKIM signing keys published for ONE domain.

Inferred read-only

blacklist_check

Check whether ONE domain or IP is listed on major email blacklists / RBLs (Spamhaus, Barracuda, SpamCop, SORBS, UCEPROTECT and more).

Potential side effects

search

Search DNSai for a domain.

Inferred read-only

fetch

Fetch a DNSai result document by id (from search).

Inferred read-only

request_api_key

Get a FREE DNSai API key that raises the daily limit from the small shared anonymous allowance to 100 lookups/day.

Inferred read-only
