Learn morePanchang and muhurat

Plain-language answers
Answers your users can read and your team can check
The API returns the numbers and says what they mean, in plain English. The text comes from fixed rules, not an AI model, so the same birth details always get the same answer.
Manglik dosha check
“Manglik dosha is present, counted from your ascendant and your Moon. On its own this is very common: by this three-way check most charts show it from at least one place.”

workable
“This match can work. The main checks pass with 22.5 out of 36 points, but a few things need a closer look before you decide.”
Real API output for Jane Doe and John Doe
See how it worksCareer reading
“Work is one of the better-supported parts of your chart. Effort here tends to turn into results and standing, often more easily than it does for other people.”

How it works
From sign-up to first result in three steps
Get a free key
Sign up and create a test key. Test keys call every endpoint, free, up to 1,000 times a month.
Send birth details
POST a date, a time and a place as JSON. The API works out the time zone and daylight saving for you.
Show the result
Use the numbers, the plain-language text, or both. Each answer names the rule it used, so your support team can explain it.
Accuracy
Accuracy you can check
We check our results against Swiss Ephemeris. The Lahiri ayanamsa (the zodiac offset) agrees within 0.001″ on 8 dates from 1900 to 2100. On our test chart, planet positions agree within 1.5″ and the rising sign within 5″. An arc second (″) is 1/3,600 of a degree. Our tests fail if a result drifts past these limits.
