FAQ

## Frequently Asked Questions

### What is a loan?

One credit is a unit of computational cost for a request. Simple lookups (e.g. `/planets`) cost 10 credits, a full natal chart - 20, synastry - 50. Full pricing on the /pricing/ page.

### What happens if I exceed the monthly quota?

Paid plans include overage - $5 / 10K credits on Indie/Starter, $3 on Pro, $2 on Business. On Starter+ you can set an overage limit to cap the amount. On Free, requests are blocked until next month.

### Can the tariff be changed at any time?

Yes. Upgrade is applied instantly, downgrade - from the next period. Unused credits of the current period are proportionally converted.

### Are the same requests cached?

Yes. Identical input within 5 minutes is returned from cache without credit deduction. The `X-Cache: HIT` header confirms this. For AI endpoints - 50% discount on cache-hit.

### How to safely provide an AI agent with an API key?

Create a separate key with a limited quota (built-in on Starter+). If the agent loops, you lose a maximum of $0.40, not the entire monthly budget.

### Accuracy of calculations?

Swiss Ephemeris - the gold standard for astrological calculations, the same library used in Solar Fire and ZET. Cross-checked with NASA Eclipse Catalog in CI on every PR. 183 snapshot tests protect all endpoints from regression.
