HTTP API

GET /v1/sun

Get data on the Sun.

Query Parameters:  

• date – reference date, in Julian day decimal format (e.g. 238490.123) or an ISO8601 time string supported by astropy.time (e.g. 2014-05-20T23:37:17)
• latitude – observer’s latitude (decimal, optional)
• longitude – observer’s longitude (decimal, optional)

Status Codes:

• 200 – success
• 400 – value error; one of the parameters passed couldn’t be parsed.

Notes

• The response will include rise and set times only if both latitude and longitude are specified.
• latitude must be between and including -90 and 90.
• longitude must be between and including -180 and 180.
• The format of latitude and longitude must be something parsable by Python’s float() function.
• It is an error to specify only one of latitude and longitude

Example request:

Get sun data for the current moment, including rise and set times for Berlin.

GET /v1/moon

Like the sun endpoint, but includes a lot more data in the response that only makes sense for the moon.
