About the URL Lookup API

URL Lookup works by analyzing the URL provided and looking up the location. It uses advanced algorithms to lookup the location of the URL and returns the location.

Ways to call it

One endpoint, many ways in — REST with JSON, XML, YAML and CSV, plus GraphQL and an MCP interface for AI agents.

JSON: Default REST response
XML: Markup format
YAML: Human-readable
CSV: Tabular export
GraphQL: Query language
MCP: For AI agents

Common questions about the URL Lookup API.

Read the docs →

What does the URL Lookup API do?

URL Lookup is a simple tool for looking up the location of a URL. It returns the location of the URL provided.

How do I authenticate URL Lookup API requests?

Pass your API key in the x-api-key header over HTTPS. One key works across all 300+ APIVerve APIs — there are no per-endpoint credentials.

How much does the URL Lookup API cost?

Each call spends 10 credits from your shared pool. The free tier includes 200 credits every month, and paid plans add more headroom.

How fast is the URL Lookup API?

Response time depends on the endpoint — the p50 through p99 latency for this API is published on this page. Requests are served over HTTPS through a global edge network.

What response formats does the URL Lookup API support?

JSON by default, plus XML and YAML via the format parameter. GraphQL and an MCP interface for AI agents are available across the catalog.

What HTTP method does the URL Lookup API use?

POST over HTTPS, following standard REST conventions with a consistent { status, error, data } response envelope.

Request parameters — POST /v1/urllookup

Sent as JSON in the request body. Premium parameters are accepted on every plan but only take effect on plans that include them. Anything not listed here is dropped rather than passed through.

Required

Parameter	Type	Example	Description
`url`Required	string	`https://www.google.com`	The URL to lookup the location of. Include the https protocol url

Example request

curl -X POST "https://api.apiverve.com/v1/urllookup" \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"url":"https://www.merriam-webster.com/dictionary/documentation"}'

Authentication

Send your key in the x-api-key header. That is the only auth step — no token exchange, and no per-endpoint scope to configure.

Header	When	Value
`x-api-key`Required	Every request	Your API key. Header names are case-insensitive, so `X-API-Key` is the same header.
`Authorization`Alternate	Instead of the above	`Bearer <key>` — for clients that only expose bearer auth. Resolves to the same account and the same billing.
`content-type`Required	POST body	`application/json`

401 is the only auth verdict

A 401 means the key is missing, invalid or expired. A 403 means the key is valid but not permitted here — blocked by a key restriction or an IP allow-list. Running out of credits is a 429.

Response — POST /v1/urllookup

Every APIVerve endpoint returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape.

Sample response

{
  "status": "ok",
  "error": null,
  "data": {
    "range": "",
    "country": "US",
    "region": "",
    "city": "Cheney",
    "timezone": "America/Chicago",
    "state": "Kansas",
    "zipcode": "67025",
    "coordinates": [
      37.751,
      -97.822
    ],
    "url": "https://www.merriam-webster.com/dictionary/documentation",
    "domain": "www.merriam-webster.com",
    "ip": "104.20.45.199",
    "countryName": "United States",
    "continent": "NA",
    "continentName": "North America",
    "accuracyRadius": 1000,
    "isEU": false
  }
}

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

Field	Type	Example	Description
`range`Premium	string	`""`	IP address range of the server
`country`	string	`"US"`	Country code where the URL is hosted
`region`Premium	string	`""`	Region or state of the URL's server location
`city`Premium	string	`"Cheney"`	City where the URL's server is located
`timezone`Premium	string	`"America/Chicago"`	Timezone of the URL's server location
`state`Premium	string	`"Kansas"`	State or province of the server location
`zipcode`Premium	string	`"67025"`	ZIP or postal code of server location
`coordinates`Premium	array	`[37.751, ...]`	Latitude and longitude coordinates of server location
`url`	string	`"https://www.merriam-webster.com/dictionary/documentation"`	The URL that was looked up
`domain`	string	`"www.merriam-webster.com"`	The domain extracted from the URL
`ip`	string	`"104.20.45.199"`	The IP address the domain resolves to (first A record)
`countryName`	string	`"United States"`	Full country name where the URL is hosted
`continent`	string	`"NA"`	Continent code of the URL's server location
`continentName`	string	`"North America"`	Full continent name of the URL's server location
`accuracyRadius`Premium	number	`1000`	Approximate accuracy radius (km) of the coordinates
`isEU`Premium	boolean	`false`	Whether the hosting country is in the European Union

Response headers

Every response carries your balance, so your own code always knows where it stands without polling anything. All four are exposed to browsers through CORS.

Header	What it carries
`x-api-remaining-credits`	Credits left in the current cycle
`x-api-credits-used`	Credits spent in the current cycle
`x-api-max-credits`	The allowance for the cycle
`x-api-version`	Version of the endpoint that answered

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change.

Status	Meaning	What to do
`400`	Input was rejected	Read `error`; it names the parameter that has to change.
`401`	Key missing or invalid	Check the header name and the key value.
`403`	Key valid, but not permitted here	A key restriction or an IP allow-list — never a bad key.
`429`	Rate limited, or out of credits	Read `error` to tell them apart, then back off or top up.

What a call costs — 10 credits per call

Credits are shared across every APIVerve API — one balance, one key, one bill. Failed requests never count against it, so a rejected input costs nothing.

Plan	Per month	Credits	URL Lookup calls	Per 1,000 calls
Free	Free	200	20	Free
Starter	$29.99	200,000	20,000	$1.50
Pro	$99.99	1,000,000	100,000	$1.00
Mega	$299.99	4,000,000	400,000	$0.75

Calls are what the credits buy at this API's rate — spend them here, on any of the other APIs, or across both. Nothing is reserved per endpoint.
