Newly Registered Domains Search

nrds

Read-onlyIdempotent

Search newly registered domains from the last 60 days by keyword, or browse a single TLD without a keyword (browsing requires a registered account). Covers generic TLDs plus more than 100 country-code TLDs, including second-level registrations such as .com.br, .co.za and .co.id (tld 'br' returns the whole .br family, 'com.br' returns that suffix alone); government, military, education and non-profit categories are not included. Which country-code TLDs you can see depends on your plan; asking for one outside it returns a message saying so. Filter by recency or exact registration dates, registration term, TLD type (generic or country-code), length, character set, sale status, and nameserver; returns the cross-TLD count for each name. New registrations are folded in continuously, typically 15 to 20 minutes after registration. Dates here are day-level, not clock times.

Input Schema

Name	Required	Description
`ns`	No	Nameserver filter, one value. A domain such as 'cloudflare.com' matches every nameserver host under it; a full host such as 'dana.ns.cloudflare.com' matches that host only.
`tld`	No	Filter by TLD, e.g. 'com', 'ai', or a second-level suffix such as 'com.br'. A two-letter country code also covers its second-level registrations ('br' includes 'com.br').
`page`	No	Page number for pagination
`sort`	No	Sort order
`type`	No	Character set filter
`length`	No	Domain name length: '<=15' is 15 characters or fewer, '>15' is 16 or more.
`period`	No	Registration term: '1' is one year, '>1' is longer than one year.
`exclude`	No	Negative keywords to exclude
`keyword`	No	Search term (min 2 chars). Substring matching applies at every length, including 2-character terms.
`has_sale`	No	Filter to domains listed for sale
`position`	No	Keyword placement in domain name. Default is 'all' (substring match).
`tld_type`	No	Limit results to country-code TLDs ('cctld', including second-level ones such as 'com.br'; only those your plan includes) or generic TLDs ('gtld'). Omit to include both.
`no_hyphen`	No	Exclude hyphenated domains
`no_number`	No	Exclude domains containing numbers
`tld_count`	No	Cross-TLD registration count of the name (the prefix_tld_count field): '<=4', '5-20' or '>20'. Domains first seen only hours ago (live rows) carry a count of 1.
`days_range`	No	Registration recency: '0-30' is the last 30 days, '31-60' is 31 to 60 days ago.
`exclude_ns`	No	Leave out domains using these nameservers. Comma-separated, up to 10 values, each matched the same way as ns.
`registered_to`	No	Registered on or before this date, YYYY-MM-DD. See registered_from.
`registered_from`	No	Registered on or after this date, YYYY-MM-DD. Combine with registered_to for a range, or set both to the same day for a single day. Takes precedence over days_range.

Output Schema

Name	Required	Description
`data`	No
`page`	No
`error`	No	Error message when success is false
`total`	No	Number of results on this page
`success`	Yes
`max_page`	No
`total_found`	No	Total matching results across all pages

A3.8/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Beyond the read-only annotations, the description discloses freshness ('15 to 20 minutes after registration'), date granularity ('day-level, not clock times'), plan-based visibility of ccTLDs, and the error behavior when a plan-excluded TLD is requested. These are valuable operational details not captured in structured fields.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is front-loaded with the core purpose and then adds detail in a logical order, but it is somewhat long. Every sentence contributes useful information, though a few details (e.g., TLD category exclusions) could be trimmed.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (19 parameters) and the presence of an output schema, the description covers all essential context: TLD scope, plan limitations, data freshness, date granularity, and available filters. Nothing critical is missing for correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so each parameter is already fully documented. The description provides a high-level summary of available filters but adds no syntax or format details beyond what the schema provides, making the baseline 3 appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb ('Search') and resource ('newly registered domains from the last 60 days') with clear scope. It distinguishes itself from generic search tools by emphasizing recency, but does not explicitly name which sibling tools (e.g., 'active', 'aged') are alternatives for different time windows.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It explains two usage modes (keyword search or TLD browsing) and notes that browsing requires a registered account. However, it gives no explicit when-to-use vs alternatives among the many sibling tools, leaving the agent to infer selection criteria.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
