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.

check_availability | Check whether a subdomain label is free before claiming it. Requires no API key. Returns { label, domain, fqdn, available, reason } where reason is 'available', 'taken', or 'invalid' (with a 'detail' explaining why the label is not usable). params: label*, domain |
signup | Create a new AgentDomains account and get an API key. Requires no existing key. IMPORTANT: the returned api_key is shown ONCE and is never retrievable again — you must store it immediately (save it to ~/.agentdomains/config.json or set AGENTDOMAINS_API_KEY) or the account is lost. The account is provisional: attach and confirm an email within 30 days (see the attach_email tool) or it is deleted al params: none |
whoami | Show the current account: id, state, attached email and whether it is verified, domains used, and which domains are available to claim under. When quotas are disabled the response omits 'quota' and says unlimited:true; 'max_subdomains' is the separate hard cap on how many names one account may hold at once (10 on the free plan, 100 on Pro). 'plan' is 'free' or 'pro'; when Pro is on sale a free acc params: none |
attach_email | Attach an email address to the account and send it a verification link. A human must click that link within 30 days or the provisional account and its domains are deleted. Use this right after signup. params: email* |
claim_domain | Register a subdomain (label.makes.fyi or label.agentdomains.co) on this account, optionally creating its first DNS record in the same call. An email is required the first time an account registers a name — pass 'email' here or call attach_email first; the name is reaped if that email is not confirmed within 30 days. Returns the fqdn and, when a record was requested, the created record. The claim a params: label*, domain, email, type, content, host |
list_domains | List every subdomain on this account, with each one's DNS records and whether it is forwarding, proxying, or delegated to external nameservers. params: none |
get_domain | Show one subdomain in full: its fqdn, DNS records, forward or proxy configuration, and delegation state. params: label*, domain |
delete_domain | DESTRUCTIVE AND IRREVERSIBLE: permanently delete a subdomain and every DNS record, forward, and proxy attached to it. The hostname stops resolving immediately and the label is released for anyone else to claim. There is no undo and no recovery. Only call this when the user has explicitly asked for this specific name to be deleted. params: label*, domain |
add_dns_record | Add a DNS record to a subdomain you already own. Use type A or AAAA to point at an IP address, CNAME to point at another hostname, or TXT for verification strings. Adding a record does not replace existing ones; use delete_record to remove a single one. Refused with a 409 while the label carries a forward or a proxy (they own the hostname) — call remove_forward or remove_proxy first, or add the re params: label*, type*, content*, host, domain |
delete_record | DESTRUCTIVE: permanently remove ONE DNS record from a subdomain, keeping the name and every other record. Use this to undo a single record — a wrong IP, a spent ACME challenge — instead of delete_domain, which takes the whole name. The record_id is the 'id' field shown by get_domain (and returned by claim_domain and add_dns_record); it is not the record's name or content. The hostname stops resolv params: label*, record_id*, domain |
add_acme_challenge | Publish a Let's Encrypt DNS-01 challenge: creates a TXT record at _acme-challenge.<label>.<domain> with the token your ACME client printed. Use this to get a certificate without exposing port 80 (for example for a wildcard cert, or a host behind NAT). DNS propagates within seconds, then tell your ACME client to continue. For a normal public web server, HTTP-01 validation needs no DNS record at all params: label*, value*, domain |
set_forward | Forward (HTTP-redirect) a subdomain to another URL. Claims the label first if you do not own it yet, in which case an email may be required exactly as for claim_domain. Defaults to a 302 temporary redirect that preserves the request path and query. HTTPS at the edge is handled for you. A forward TAKES OVER the hostname: any A/AAAA/CNAME record on the label itself is deleted as part of this call an params: label*, target*, permanent, preserve_path, cloak, email, domain |
remove_forward | Stop forwarding a subdomain. The name itself stays registered on the account; only the redirect is removed. params: label*, domain |
set_proxy | Serve a backend at this subdomain through the AgentDomains edge, which terminates TLS with its own certificate — this is how you get working HTTPS on an origin that has no certificate of its own (a bare IP-less PaaS host, a tunnel, an internal box). Unlike a forward, the URL stays on your domain and the response is proxied, not redirected. Claims the label first if needed. Like a forward, a proxy params: label*, origin*, email, domain |
remove_proxy | Stop reverse-proxying a subdomain, so the edge no longer serves the backend or terminates TLS for it. The name stays registered on the account. params: label*, domain |
delegate_nameservers | Delegate the subdomain to your own nameservers, handing you full control of it and everything beneath it (your own records, MX, deeper sub-domains). AgentDomains stops answering for the name, so its existing records, forwards, and proxies no longer apply. Supply at least two nameservers. params: label*, nameservers*, domain |
delete_account | DESTRUCTIVE AND IRREVERSIBLE, AND THE LARGEST ONE HERE: delete the whole AgentDomains account and invalidate its API key, which cannot be recovered or reissued — every later tool call fails with a 401 until a new signup. Without force it REFUSES while the account still holds names, answering 409 with the list of them; that refusal is a safety net, so show the list to the user and get an explicit y params: force |
upgrade_to_pro | Get a Stripe checkout link for AgentDomains Pro: 100 names instead of the free 10, names never released for being unreachable, and priority email support, for $5/month (or $48/year with interval 'year'). Use this when a claim is refused because the account is at its name limit and the user wants more. It only returns a link and never charges anything: a human must open the URL and pay. Show them t params: interval |
manage_billing | Get a Stripe billing-portal link for a Pro account: update the card, see invoices, switch between monthly and yearly, or cancel. A human must open it. Cancelling keeps Pro to the end of the paid period and never deletes a name. Answers 409 if the account has never subscribed (use upgrade_to_pro). params: none |
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.
