Random Data Generator API

GET

Seed test suites and staging databases with realistic mock data.

Random Data Generator produces mock values including names, emails, addresses, dates, and UUIDs for application testing. Specify a supported data type to receive a generated record; paid plans can generate batches up to 100 items.

About the Random Data Generator API

Random Generator works by generating random data based on the type specified. It can generate random numbers, strings, dates, and more. The data is generated using advanced algorithms to ensure randomness and unpredictability.

What people use it for

Database Seeding: Populate staging tables with synthetic names, addresses, and phone numbers before running integration tests against newly deployed schemas.
UI Prototype Mocking: Front-end developers render placeholder user profiles with generated usernames, emails, and hex colors while building interface layouts.
Unique Key Generation: When verifying record deduplication pipelines, QA engineers inject generated UUIDs and timestamps into intake streams.
Game Mechanics Simulation: To test random drop rates and turn orders, game creators draw coin flips and dice rolls directly into prototype loops.

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

Questions.

Common questions about the Random Data Generator API.

Read the docs →

What types of mock data can I generate?

You can generate values such as names, email addresses, phone numbers, dates, strings, and numbers. If you need to inspect every available category programmatically, you can query the list endpoint to retrieve all supported types.

Can I generate profile photos alongside user names?

Yes, on paid plans. When setting the type to name, you can enable the avatar parameter to receive an AI-generated face image with each record. This option applies specifically to name requests and is ignored on other data types.

What is the maximum number of items returned per request?

The Free plan returns 1 item per call; on paid plans, the count parameter accepts values between 1 and 100 per call. If your application requires larger datasets, you will need to make multiple requests.

Can I request batches or AI avatars on the Free plan?

No, batch generation and profile avatars require a paid plan. Specifying a custom count up to 100 items or enabling AI-generated face avatars are premium features available on Starter and higher. The Free plan is limited to single-item requests without avatars.

Which plan fits 25,000 mock data requests a month?

The Starter plan easily covers that volume. Each request costs 2 credits, so 25,000 calls use 50,000 of Starter's 200,000 credits, working out to about $0.30 per 1,000 calls. The Free plan provides 100 calls per month for testing.

Request parameters — GET /v1/randomgenerator

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.

Optional

Parameter	Type	Example	Description
`type`Optional	string	`number`	The type of random data to generate `numberdicephonedatecoinuuidguidcolor`+4 default number
`count`OptionalPremium	integer	`10`	The number of random data to generate (1 to 100) default 1 · range 1-100
`includeAvatar`OptionalPremium	boolean	`true`	Include an AI-generated face avatar (only applies when type=name) default false

Example request

1
2

curl "https://api.apiverve.com/v1/randomgenerator?type=phone&count=10&includeAvatar=true" \
  -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/randomgenerator

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": {
    "type": "phone",
    "count": 10,
    "data": [
      "967-950-4587",
      "792-611-7468 x1293",
      "(933) 311-9829",
      "389.357.7403 x793",
      "1-621-490-6394",
      "1-699-562-6833 x8558",
      "875.226.1530 x641",
      "744-991-0150 x1974",
      "1-393-784-0533 x15199",
      "954-876-6958 x0398"
    ]
  }
}

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
`type`	string	`"phone"`	The kind of random data generated (e.g. phone, name, email)
`count`	number	`10`	Number of random values generated
`data`	array	`[967-950-4587, ...]`	The generated random values; item shape depends on the requested type

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	Random Data 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.
