Moon Position API

GET

Pinpoint the moon's position in the sky from any coordinates.

Moon Position calculates the moon's altitude in the sky for any latitude and longitude coordinates. Provide an optional time of day to determine lunar elevation; paid plans add custom dates, azimuth, and distance.

About the Moon Position API

Moon Position works by analyzing the location provided and calculating moon position data. It uses advanced algorithms to calculate data such as altitude, azimuth, and distance of the moon from the location and returns the moon position data.

What people use it for

Night Photography Planning: Landscape photographers check moon altitude across evening hours to time foreground illumination and align night-sky shots.
Telescope Pointing Assistants: Amateur astronomy software plots lunar elevation by observer coordinates to guide telescope targeting during backyard stargazing sessions.
Coastal Night Navigation: When planning coastal night voyages, marine navigation tools track lunar altitude to anticipate natural visibility over open water.
Nocturnal Wildlife Research: Field biology platforms log lunar elevation against animal GPS tracks to correlate predator hunting patterns with ambient moonlight.

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 Moon Position API.

Read the docs →

Is it cheap enough to calculate the moon's position for every user request?

Yes. Each request uses 2 credits, which works out to about $0.30 per 1,000 calculations on the Starter plan. The Starter plan includes 100,000 monthly calls, while the Free plan gives you 100 calls per month to test your integration.

Are azimuth, distance, and custom dates included on the Free plan?

No. Azimuth, distance in kilometers, and the ability to query specific dates are premium features. The Free plan returns the moon's altitude for current dates, while any paid plan unlocks full directional azimuth, distance calculations, and historical or future date lookups.

Does this work for any latitude and longitude worldwide?

Yes. You can supply any valid geographic coordinates across the globe. The calculation determines the moon's altitude and position relative to that exact observer location on Earth.

What happens if I omit the time parameter?

If you do not pass a time, the calculation defaults to midnight (00:00). When you need precision for a specific moment, provide the time in standard 24-hour HH:mm format.

Can I use moon position data in a commercial photography or outdoor app?

Yes, commercial use is fully allowed on any paid plan. You can calculate and display position metrics inside your consumer or business application, as long as you do not resell or redistribute the raw API data as a standalone service.

Request parameters — GET /v1/moonposition

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
`lat`Required	number	`37.7749`	The latitude of the location range -90-90
`lon`Required	number	`-122.4194`	The longitude of the location range -180-180

Optional

Parameter	Type	Example	Description
`date`OptionalPremium	string	`01-16-2026`	The date to get the moon position data for (MM-dd-yyyy) date
`time`Optional	string	`14:30`	The time of day for the calculation (HH:mm format, 24-hour). Defaults to 00:00 if not provided time
`timezone`Optional	string	`America/Los_Angeles`	IANA timezone name the date and time are given in. Defaults to the timezone of the supplied coordinates timezone

Example request

2

curl "https://api.apiverve.com/v1/moonposition?lat=37.7749&lon=-122.4194&date=01-16-2026&time=14%3A30&timezone=America%2FLos_Angeles" \
  -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/moonposition

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": {
    "date": "01-22-2026",
    "time": "14:30",
    "coordinates": {
      "latitude": 37.7749,
      "longitude": -122.4194
    },
    "moon": {
      "altitude": -0.407908976399288,
      "azimuth": 1.4720499058762104,
      "distance": 404332.6834067969
    }
  }
}

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
`date`	string	`"01-22-2026"`	The date for which moon position was calculated
`time`	string	`"14:30"`	The time of observation in HH:MM format
`coordinates`	object	`{...}`	The observation location the position was calculated for
`latitude`	number	`37.7749`	The latitude coordinate of the observation location
`longitude`	number	`-122.4194`	The longitude coordinate of the observation location
`moon`	object	`{...}`	The moon's position as seen from the observation location
`altitude`	number	`-0.407908976399288`	Moon altitude above the horizon in radians, calculated from observation location. Negative values mean the moon is below the horizon
`azimuth`Premium	number	`1.4720499058762104`	Moon azimuth in radians, derived astronomical calculation
`distance`Premium	number	`404332.6834067969`	Distance from observer to moon in kilometers

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	Moon Position 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.
