Questions.

Common questions about the Bingo Card Generator API.

Read the docs →

What grid sizes and formats can I generate?

You can generate bingo cards ranging from 3x3 up to 10x10 grids. Every card contains randomized numbers and can be returned as a raw 2D array, a pre-rendered HTML table, or a downloadable PNG image.

How many bingo cards does the Free plan cover?

The Free plan provides 200 monthly credits, which covers 100 bingo cards at 2 credits per call. If you need more, the Starter plan covers up to 100,000 cards per month, which works out to about $0.30 per 1,000 cards.

Are HTML tables and downloadable PNG images included on the Free plan?

No. The pre-rendered HTML table and downloadable PNG image URLs are premium fields that require any paid plan. The Free plan returns the card as a raw 2D array of numbers along with grid metadata.

What are the restrictions on card size and free spaces?

Card dimensions must be between 3x3 and 10x10. You can toggle the center free space parameter on or off, which places a free space in the center cell of the generated card.

Does the response include winning combinations to validate games?

Yes. Each response includes a list of valid winning patterns calculated for that card dimension alongside the grid data, total cell count, and free space flag.

Request parameters — GET /v1/bingocardgenerator

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
`size`Optional	integer	`5`	Card size (3x3 to 10x10) default 5 · range 3-10
`freeSpace`Optional	boolean	`true`	Include free space in center default true
`image`OptionalPremium	boolean	`true`	Set to true to generate a downloadable bingo card image default false

Example request

1
2

curl "https://api.apiverve.com/v1/bingocardgenerator?size=5&freeSpace=true&image=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/bingocardgenerator

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.

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
`card`	array	`Array of arrays`	2D array of bingo card numbers and FREE space
`html`Premium	string	`"<html><head><title>Bingo Card</title><style>body {font-family: Arial, sans-serif; padding: 20px;}table {border-collapse: collapse; margin: …`	Rendered HTML table of bingo card for display
`size`	number	`5`	Dimensions of the bingo card grid
`freeSpace`	boolean	`true`	Whether center free space was included
`totalCells`	number	`25`	Total number of cells in the card
`winningPatterns`	array	`[horizontal, ...]`	Possible winning patterns for bingo game
`image`	object	`{...}`
`imageName`Premium	string	`"8dcb6cee-a419-4501-a13c-ff6eafd393b7_bingo.png"`	Unique filename of generated bingo card image
`format`	string	`".png"`	File format extension of image file
`downloadURL`Premium	string	`"https://storage.googleapis.com/apiverve/APIData/bingocardgenerator/8dcb6cee-a419-4501-a13c-ff6eafd393b7_bingo.png?GoogleAccessId=6355003980…`	Signed URL to download generated bingo card image
`expires`Premium	number	`1766010022446`	Unix timestamp when image download URL 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	Bingo Card 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.
