Questions.

Common questions about the Birthstones API.

Read the docs →

Can I look up gemstones by zodiac sign as well as month?

Yes. The API supports lookups by calendar month number or name, zodiac sign, or gemstone name. You can also fetch the entire reference dataset in one call.

Are gemstone meanings and hardness ratings included on the Free plan?

No. The Free plan returns the month, primary gemstone, color, and associated zodiac signs. Detailed fields like alternate stones, symbolism and meaning, Mohs hardness, mineral family, and anniversary year require any paid plan.

How many birthstone lookups does the Free plan cover?

The Free plan covers 200 lookups every month. Each call costs 1 credit, using your 200 monthly credits. If you need higher volume, the Starter plan covers 200,000 lookups a month, which works out to about $0.15 per 1,000 calls.

Can I tell if a stone is a primary birthstone or an alternate?

Yes. When searching by gemstone name, the response returns a specific flag that confirms whether the stone is a month's traditional primary gemstone or an alternate choice.

Can I display birthstone details in a commercial jewelry store or gift finder?

Yes, as long as you are on a paid plan. Commercial use is permitted on Starter and above. You can display gemstone properties, colors, and meanings directly to your shoppers, provided you do not resell the raw data.

Request parameters — GET /v1/birthstones

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
`month`Required	string	`5`	The month number (1-12) or name `12345678`+16

Example request

1
2

curl "https://api.apiverve.com/v1/birthstones?month=5" \
  -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/birthstones

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": {
    "count": 1,
    "birthstones": [
      {
        "month": 5,
        "monthName": "May",
        "primaryStone": "Emerald",
        "alternateStones": [
          "Chrysoprase",
          "Agate"
        ],
        "color": "Green",
        "meaning": "Rebirth, love, fertility",
        "zodiacSigns": [
          "Taurus",
          "Gemini"
        ],
        "hardness": 7.5,
        "mineralFamily": "Beryl",
        "anniversaryYear": 55
      }
    ]
  }
}

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
`count`	number	`1`	Number of months returned
`birthstones`	array[1]		The birthstones for each month requested
`month`	number	`5`	Birth month number from 1 to 12
`monthName`	string	`"May"`	Full name of the birth month
`primaryStone`	string	`"Emerald"`	Primary gemstone for the month
`alternateStones`Premium	array	`[Chrysoprase, ...]`	Alternate gemstones associated with month
`color`	string	`"Green"`	Traditional color associated with stone
`meaning`Premium	string	`"Rebirth, love, fertility"`	Symbolism and meaning of the birthstone
`zodiacSigns`	array	`[Taurus, ...]`	Zodiac signs associated with month
`hardness`Premium	number	`7.5`	Mohs hardness rating of gemstone
`mineralFamily`Premium	string	`"Beryl"`	Mineral classification family
`anniversaryYear`Premium	number	`55`	Anniversary year associated with stone

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 — 1 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	Birthstones calls	Per 1,000 calls
Free	Free	200	200	Free
Starter	$29.99	200,000	200,000	$0.15
Pro	$99.99	1,000,000	1,000,000	$0.10
Mega	$299.99	4,000,000	4,000,000	$0.07

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.
