api documentation dns tools tools api introduction authentication requests responses rate limits errors dns api domain api api guide introduction authentication requests responses rate limits errors tool apis dns api domain api dns tools api built for developers who need fast reliable and accurate domain and website intelligence our platform abstracts away the complexities of dns whois and rdap so you can focus on building reliable applications the api uses restful principles and returns json responses queries are made over https with simple get requests all endpoint urls use the following pattern api endpoint pattern get https api dns tools v1 tool query parameters additional resources for working with the dns tools api openapi spec swagger ui llms txt authentication free tier no api key we offer a generous free tier that requires no authentication so you can start using the api immediately please contact us for an api key to access higher rate limits you can begin using the api without registration or authentication the free tier is perfect for testing and light usage get try it api key authentication for higher rate limits and production use you can authenticate using an api key we support three methods of providing your api key header authentication methods x api key your api key header provide your api key in an http request header authorization bearer your api key header authenticate using standard bearer token format query parameter authentication key your api key querystring provide your api key as a url query parameter example authenticated requests authentication examples using x api key header curl x get https api dns tools v1 domain google com h x api key your api key using authorization bearer token curl x get https api dns tools v1 domain google com h authorization bearer your api key using query parameter curl x get https api dns tools v1 domain google com key your api key javascript fetch example const response await fetch https api dns tools v1 domain google com method get headers x api key your api key or with authorization bearer token don t need both authorization bearer your api key const data await response json making requests all api requests are made using simple get requests the api follows a simple restful url structure where the tool and query are specified in the path with optional parameters provided as query strings all endpoints use the following url pattern api endpoint pattern curl x get https api dns tools v1 tool query parameters api endpoint components tool string required the specific api tool to use for analysis not all tools are currently supported through the api examples dns domain query string required the domain name hostname ip address or other query target international domain names idn can be provided in either unicode or punycode format examples google com sub domain com билеты сайт 192 168 72 1 parameters querystring additional query parameters to pass to the tool see the tool specific documentation for all available tool options examples type a server 8 8 8 8 dnssec true response format all api responses follow a consistent json structure and share common request metadata fields with a results array containing the tool specific results successful responses return http 200 status codes while errors return appropriate 4xx or 5xx status codes with detailed error information see errors below api response example tool dns query google com requestid a7f9c2d4 8e1b 4c3a 9f6e 2d8b5e7c1a9f timestamp 2025 01 15t10 30 00 000z elapsed 35 errorcode null errorname null

to the api examples google com sub domain com билеты сайт 192 168 72 1 requestid string a unique identifier for this request useful for debugging and support examples a7f9c2d4 8e1b 4c3a 9f6e 2d8b5e7c1a9f timestamp string the timestamp when the request was processed in iso 8601 format examples 2025 01 15t10 30 00 000z elapsed number the time taken to process the request in milliseconds cached boolean whether the request was served from cache by default we cache results for up to 24 hours examples true false results array nullable an array containing the tool specific data examples errorcode number nullable an http status code for the error or null for successful requests examples 400 401 429 500 errorname string nullable human readable error name or null for successful requests examples invalid query unauthorized too many requests errormessage string nullable detailed error message or null for successful requests examples the provided query is not a valid domain name rate limits we implement rate limiting to maintain service quality for all users rate limits depend on your usage tier and are applied per ip address for the free tier and per api key for authenticated requests if the limit is exceeded your access will be throttled and the api will return a 429 status code implement incremental backoff in your retry logic and consider spreading requests over time to avoid exceeding the limit need higher rate limits contact us at support dns tools to discuss your requirements and get access to a higher tier we also offer custom solutions for high volume users and enterprise customers errors when an error occurs the api returns an appropriate http status code along with the same json structure as successful responses but with the error fields populated with details and the results set to null http status codes 200 ok request was successful the response contains the requested data in the results field 400 bad request invalid tool query or parameters check the url structure and parameter values 401 unauthorized invalid missing or expired api key verify your api key is correct and your account is active 429 too many requests rate limit exceeded wait before making more requests or upgrade for increased limits 500 internal server error an unexpected error occurred while processing your request please try again later or contact support with the requestid you can reach us at support dns tools check both the http status code and the errorcode field in the response implement retry logic with incremental backoff for transient errors 5xx status codes error response example tool dns query invalid domain nope requestid b3e8f1a6 7c2d 4b9e 8f5a 3c6d9e4f2b8c timestamp 2025 01 15t10 30 00 000z elapsed 125 errorcode 400 errorname invalid query
