About the TOTP Generator API

Provides token expiration tracking and remaining time information, compatible with Google Authenticator and other TOTP applications.

What people use it for

2FA Implementation: Implement two-factor authentication systems with TOTP token generation
Authentication Testing: Test TOTP-based authentication flows in development and QA environments
Security Integration: Integrate time-based one-time passwords into security workflows
MFA Systems: Build multi-factor authentication systems with standardized TOTP tokens

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 TOTP Generator API.

Read the docs →

What does the TOTP Generator API do?

TOTP Generator creates time-based one-time passwords compatible with authenticator apps using standard TOTP algorithms.

How do I authenticate TOTP 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 TOTP 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 TOTP 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 TOTP 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 TOTP Generator API use?

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

Request parameters — POST /v1/totpgenerator

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
`secret`Required	string	`JBSWY3DPEHPK3PXP`	Base32-encoded shared secret

Optional

Parameter	Type	Example	Description
`digits`Optional	integer	`6`	Number of digits in token default 6 · range 6-8
`period`Optional	integer	`30`	Time period in seconds default 30 · range 1-300

Example request

curl -X POST "https://api.apiverve.com/v1/totpgenerator" \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"secret":"JBSWY3DPEHPK3PXP","digits":6,"period":30}'

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/totpgenerator

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": {
    "token": "935324",
    "digits": 6,
    "period": 30,
    "timeRemaining": 25,
    "expiresAt": "2025-12-16T22:31:00Z"
  }
}

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
`token`	string	`"935324"`	Generated time-based one-time password token
`digits`	number	`6`	Number of digits in the generated token
`period`	number	`30`	Time period configured for token generation
`timeRemaining`Premium	number	`25`	Seconds remaining until token expires
`expiresAt`Premium	string	`"2025-12-16T22:31:00Z"`	ISO 8601 timestamp when token expires

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	TOTP 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.
