The cost of 1,000 calls is the plan price split over all its calls. The same price also pays for the reading credits. Fair use applies to every plan. See the Terms.

How many calls and reading credits does each plan include?
Each month, the Free plan gives 2,000 calls and 150 reading credits for $0. Starter gives 50,000 calls and 1,000 credits for $29. Growth gives 250,000 calls and 5,000 credits for $99. Scale gives 2,000,000 calls and 22,000 credits for $399. Test keys add 1,000 free test calls a month on every plan.
What do 1,000 API calls cost on each paid plan?
At today's monthly prices, 1,000 calls cost about $0.58 on Starter, $0.40 on Growth and $0.20 on Scale. That is the plan price divided by its monthly calls. Written readings use reading credits instead of calls. Failed calls and free endpoints, such as the health check, cost nothing.
Is a yearly plan cheaper than paying monthly?
Yes. A yearly plan costs the price of 10 months and runs for 12, so 2 months are free. Starter is $290 a year instead of $348. Growth is $990 a year instead of $1,188. Scale is $3,990 a year instead of $4,788. Prices are in US dollars, before tax.
What a call costs
What does one call or one written reading cost?
On API for Astrology (apiforastrology.com), one calculation call costs under 1 cent on every paid plan. At launch prices, reading credits cost about $18.14 to $29.00 per 1,000, and a chapter uses 1 credit. A full report of 25 credits costs about $0.45 to $0.73.
The launch price runs until Mar 31, 2027. Amounts are in US dollars, rounded to the cent, before tax.

How are these costs worked out?
Each cost is the monthly plan price split over one monthly allowance, as if you use all of it. Calculations use calls, and written readings use reading credits. One plan price buys both, so extra credits can cost less per 1,000 than the plan's own. Amounts are in US dollars, rounded to the cent, before tax.
How should I compare astrology API prices?
Compare the cost of a finished result, not a request or credit. Some APIs charge different credits per endpoint, so a cheap credit can still mean a costly chart. A birth chart is one call here. 1,000 charts cost about $0.20 to $0.58. A full report costs about $0.45 to $0.73, and a numerology profile about $0.05 to $0.09.
What do extra calls and extra reading credits cost?
Extra calls are never billed. Past the monthly calls, the API answers 429 until the 1st of the month (UTC). A bigger plan ends the wait. On paid plans, pay as you go adds extra reading credits, up to a cap you set. Per 1,000 extra credits, the price is $30.00 on Starter, $22.00 on Growth and $18.00 on Scale.
Written readings
What reading credits buy
Each written reading uses the credits below from your monthly allowance. Calculations use calls instead.
What reading credits buy: the credits each written reading uses
One question, such as marriage, work, money or a lost item, read from the moment it is asked. A short answer with its reasons, and an estimate of when. No birth details needed
The KP way to read one question: the person picks a number from 1 to 249 and a topic. A short answer with its reasons, and the likely period. No birth details needed
A year of sky events read against the chart: career, love, money, key periods and remedies
25
Example: Growth's 5,000 credits buy 200 full reports, or 5,000 chapters, or any mix.
Credits are the same in every language, and for standard or longer text. Failed requests use nothing. Each response shows what it used in the X-Calls-Counted and X-Reading-Credits-Counted headers.
Numerology API pricing
The Numerology API uses the same key, the same plan and the same reading credits. Each numerology answer is a full written reading in English or Hindi. So each one uses reading credits and no calls. Short checks use 1 credit. The profile bundles all your core numbers with a reading for each. The full report costs the same as the astrology full report, so every plan counts reports the same way.
What numerology credits buy: the credits each numerology endpoint uses
The whole numerology reading, as a web page or as JSON.
25
The same credits in every language, and at standard or expanded length. Test keys use no credits: each numerology test call counts as 1 test call and answers for the sample people only.
Type what you expect each month. Test keys do not count: they have their own free allowance.
The smallest plan that fits

You need 30,000 calls and 1,250 reading credits a month. Growth has 250,000 calls and 5,000 reading credits.

Reading credits are what written readings use. Calculations, such as birth charts, dasha, panchang and kundli matching, use calls. A written reading uses credits instead: 1 for a chapter, 25 for a full report. Each plan has a monthly allowance of credits: Free 150, Starter 1,000, Growth 5,000 and Scale 22,000.
The written readings: one chapter; life summary; karma reading; spiritual path reading; love, career or wealth forecast; weekly reading; varshaphal (annual chart); couple forecast; full report; annual forecast; question chart (prashna); and kp question chart (kp horary). Everything else uses calls, including the daily horoscopes, the list of chapters and the rule list. Credits are the same in every language, and for standard or longer text.
What happens if I use up my calls?+
Calculations get a 429 answer, with a Retry-After header, until the 1st of the next month (UTC) or a move to a bigger plan. Calls already in progress at that moment still finish, and any calls over your allowance come off next month's. Reading credits are separate, so readings keep working while credits are left. We never charge extra for calls.
What happens when reading credits run out?+
A reading that does not fit in the credits left gets a 429 answer with the code reading_credits_exceeded. That lasts until the 1st of the month (UTC), or until you move to a bigger plan. Calculations keep working. Without pay as you go, credits never go past your allowance, so there is nothing extra to pay.
How does pay as you go work?+
Pay as you go is for paid plans. Turn it on in Billing and set a monthly cap ($50 unless you change it). When your reading credits run out, readings keep working, and you pay for the extra credits each month. The price is $0.75 a full report on Starter, $0.55 a full report on Growth and $0.45 a full report on Scale. On a monthly plan, the extras are a line on your plan's monthly invoice, in the same payment. On a yearly plan, they come on a separate monthly invoice with no monthly fee. At the cap, readings answer 429 until the 1st (UTC). Extra credits are not refunded.
Yes. Test keys return every reading in full, free, on every plan. They work for the sample charts in the docs: John Doe (New York) and Jane Doe (Chicago). And the Free plan gives 150 reading credits a month for any chart: about 6 full reports, or 150 chapters.
Can I use the API in an app or site I sell?+
Yes. On every plan, you may show API output to your own users, in a free or a paid product. Paid plans need no link to us. One exception: on Starter, a public page with the 12 daily sign horoscopes must link to us. The Free plan needs a visible "Powered by API for Astrology" link. You may not resell the output as your own data feed or API.
Yes, once real users see it. On the Free plan, each page or screen with API output needs a visible link. It reads "Powered by API for Astrology" and goes to https://apiforastrology.com. It can go in the footer of that page, for example. Test keys need no link, and paid plans need none, except the daily sign horoscopes on Starter.
No. Calls and reading credits start again on the 1st of each month (UTC), and unused ones do not carry over.
Does one plan cover every API you offer?+
Yes. One plan, one account and one set of keys cover the Astrology API and the Numerology API, with one invoice. Both use the same calls and reading credits.
Every numerology answer is a written reading. So it uses reading credits, never calls. A name or phone number check uses 1 credit, and a full report uses 25. The price is the same in every language. Failed requests are free.
Choose a plan and pay by card on a secure checkout page. Our reseller, Dodo Payments, handles the payment and the tax, and emails you an invoice. The plan applies within a minute of paying.
Can I change or cancel my plan?+
Yes, from Billing in your account. A bigger plan applies at once, and you pay only the difference for the rest of the period. A smaller plan starts on your next billing date. If you cancel, the plan runs to the end of the period you paid for, then your account moves to Free.
What if a payment fails?+
Your plan keeps working while the payment is retried, for up to 7 days after the paid period ends. Update your card in Billing to keep it. After that, your account moves to Free and your keys keep working within the Free limits.
Do you give refunds?+
Payments are final, but we refund double or mistaken charges. The refund policy has the details.
Yes, if it breaks the Terms. Examples are copying the reading text in bulk, getting around a limit, or opening more than one Free account. Fair use applies to every plan. A Free account can be disabled without notice if we find the API being misused there. The Terms list the rules and what happens when an account is suspended.
