About the User Agent Generator API

User Agent Generator works by generating a random user agent string based on the browser, operating system, and device. It returns the generated user agent string in a structured format.

What people use it for

Web Scraping: Use the User Agent Generator API to generate user agent strings for web scraping. Use the data to scrape websites, collect data, and automate tasks
Browser Testing: Generate user agent strings by using the User Agent Generator API for browser testing. Use the data to test compatibility, verify functionality, and ensure performance
Device Simulation: Simulate devices by using the User Agent Generator API to generate user agent strings. Use the data to emulate devices, test responsiveness, and optimize layouts
Website Testing: Test websites by using the User Agent Generator API to generate user agent strings. Use the data to test functionality, verify compatibility, and ensure performance

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

Other ways to use User Agent Generator

Same data, same APIVerve account, same credit balance — one key works on all of them.

Give it to an AI agentConnect over MCP and your agent calls it as a native tool — Claude, Cursor, ChatGPT.on VerveKit

Questions.

Common questions about the User Agent Generator API.

Read the docs →

What does the User Agent Generator API do?

User Agent Generator is a simple tool for generating user agent strings. It returns a random user agent string.

How do I authenticate User Agent Generator 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 User Agent Generator API cost?

Each call spends 2 credits from your shared pool. The free tier includes 200 credits every month, and paid plans add more headroom.

How fast is the User Agent Generator 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 User Agent Generator 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 User Agent Generator API use?

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

Request parameters — GET /v1/useragentgenerator

Sent in the query string. 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
`device`Required	string	`desktop`	The device type for the user agent string `desktopmobiletablet` default desktop

Example request

1
2

curl "https://api.apiverve.com/v1/useragentgenerator?device=desktop" \
  -H "x-api-key: YOUR_API_KEY"

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.

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 — GET /v1/useragentgenerator

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": {
    "ua": "Mozilla/5.0 (Windows NT 6.4) AppleWebKit/537.36.0 (KHTML, like Gecko) Chrome/94.0.0.0 Safari/537.36.0",
    "browser": {
      "name": "Chrome",
      "version": "94.0.0.0",
      "major": "94"
    },
    "engine": {
      "name": "Blink",
      "version": "94.0.0.0"
    },
    "os": {
      "name": "Windows",
      "version": "10"
    },
    "device": {},
    "cpu": {}
  }
}

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
`ua`	string	`"Mozilla/5.0 (Windows NT 6.4) AppleWebKit/537.36.0 (KHTML, like Gecko) Chrome/94.0.0.0 Safari/537.36.0"`	Complete user agent string representing browser environment
`browser`	object	`{...}`
`name`	string	`"Chrome"`	Name of the browser (e.g., Chrome, Firefox, Safari)
`version`	string	`"94.0.0.0"`	Full browser version number including all segments
`major`	string	`"94"`	Major version number of the browser
`engine`	object	`{...}`
`name`Premium	string	`"Blink"`	JavaScript engine name (e.g., Blink, WebKit, Gecko)
`version`Premium	string	`"94.0.0.0"`	JavaScript engine version number
`os`	object	`{...}`
`name`	string	`"Windows"`	Operating system name (e.g., Windows, macOS, Linux)
`version`	string	`"10"`	Operating system version number
`device`Premium	object	`{...}`	Device information object containing vendor and model details
`cpu`Premium	object	`{...}`	CPU architecture and processor information

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 — 2 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	User Agent Generator calls	Per 1,000 calls
Free	Free	200	100	Free
Starter	$29.99	200,000	100,000	$0.30
Pro	$99.99	1,000,000	500,000	$0.20
Mega	$299.99	4,000,000	2,000,000	$0.15

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.
