Is this your server? Own a server? ToolFit hosted watch re-checks it every 24 h ($0.25 per 30 days) or 6 h ($0.60) and sends you an HMAC-signed webhook when its tools or grade change: POST https://api.youraitools.co/toolfit/v1/watch. To opt out, see About & opt-out.
Tools: domain_lookup whois_lookup dns_records ssl_certificate subdomains email_security
domain_lookup | Full report on a domain in one call: WHOIS/RDAP registration, DNS records, live SSL
certificate, subdomains (live hosts with IPs first) and email authentication (SPF, DMARC, DKIM).
Use it to triage a suspicious domain or profile a company's domain. If one section fails it comes
back as an object with an `error` field and the rest is unaffected. Set wait=true to wait for every
subdo params: domain*, wait, subdomain_limit |
whois_lookup | Registration data for a domain: registrar, created, updated and expiry dates, nameservers and
status. RDAP first (rdap.org, IANA bootstrap, 22 fallback servers), then port-43 WHOIS for 60+
TLDs. `_source` says which one answered. Use it for domain age, expiry or registrar checks. params: domain* |
dns_records | DNS records for a domain: A, AAAA, MX, TXT, NS, CAA and SOA, resolved in parallel. params: domain* |
ssl_certificate | The certificate a domain serves on port 443, from a live TLS handshake: issuer, subject,
valid_from, valid_to, days_until_expiry, SANs, signature algorithm and serial number. params: domain* |
subdomains | Subdomains of a domain from certificate transparency logs, passive DNS and DNS brute force.
`live` lists hosts that resolve now, each with its IP; `subdomains` lists every name found, live
first; `pools` summarises large shared-infrastructure zones. The first lookup of a domain is a fast
snapshot and later ones are fuller; set wait=true to wait for every source (up to about 20 s). params: domain*, wait, limit |
email_security | Email authentication for a domain: SPF and DMARC records, and DKIM keys found by probing about
29 common selectors (Google, Microsoft 365, Mailchimp, SendGrid and others). Custom selectors
may not be found. params: domain* |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
