“Free astrology API” usually means one of three things: a generous monthly credit grant, a hard daily request cap, or a time-limited trial that turns into a paywall. They are not the same, and the difference decides whether you can ship a side project without a card. Here’s how the main options actually compare.
The short answer
Section titled “The short answer”AstroWay’s free tier is 10,000 credits per month, no credit card. A full natal chart is 20 credits, so that’s roughly 500 charts a month before you pay anything - the most generous standing free tier among the commercial astrology APIs as of 2026.
Free tiers side by side
Section titled “Free tiers side by side”| API | Free allowance | Card required? | Notes |
|---|---|---|---|
| AstroWay | 10,000 credits/mo (~500 natal charts) | No | Standing monthly grant across all 761 endpoints |
| Prokerala | ~2,500 credits | No | Vedic-focused; credit costs vary widely per endpoint |
| FreeAstrologyAPI | ~50 requests/day | No | Hard daily cap, no SDK |
| DivineAPI | 14-day trial | Yes (usually) | Trial, not a standing free tier |
| Vedika | No live free tier | – | Paid from the start |

”Credits” vs “requests” - read the unit
Section titled “”Credits” vs “requests” - read the unit”A daily request cap (FreeAstrologyAPI’s ~50/day) is predictable but small, and a single complex call counts the same as a trivial one. Credit grants (AstroWay, Prokerala) price by what the endpoint computes - a planet lookup is cheap, a rectification is not - so a credit tier stretches further for a mix of light calls. The catch with some credit systems (Prokerala’s is the usual example) is that a few heavy endpoints can burn a month’s budget fast, which makes planning hard. AstroWay’s per-endpoint costs are flatter and published on the pricing page.
What 10,000 credits actually builds
Section titled “What 10,000 credits actually builds”At 20 credits per natal chart, 10,000 credits is about 500 charts a month. In practice that covers:
- a personal project or MVP serving real users before any revenue,
- a daily-horoscope widget caching twelve sign-based calls per day (a few credits each),
- local development and CI without touching a paid key.
When you outgrow it, the first paid tier starts at $5/mo.
How to start
