Occult API

Pay for what you call

Choose a monthly or yearly plan with a monthly quota. One successful call is one credit (PDF reports and AI chat: 25 credits), and failed requests cost nothing.

Plans

Renews automatically and your quota resets every month, on yearly plans too. Cancel any time.

Questions

What counts as one credit?
One successful API call (a PDF report or an AI chat answer costs 25). It does not matter how many calculations you ask for in it — requesting six keys in one call costs one credit, where six separate calls would cost six.
Am I charged for failed requests?
No. A 4xx caused by your request and a 5xx caused by us both cost nothing. Every response carries X-Credits-Charged so you can see exactly what was billed.
Do credits expire?
A plan's quota resets at the start of each month, so what you do not use in a month does not roll into the next one. That holds on yearly plans too: a yearly plan is twelve monthly allowances, billed once.
What happens when I run out?
Calls return 402 Payment Required with a clear message, and your keys keep working. Move to a larger plan from Billing and they resume immediately — no new key needed — or wait for your quota to reset at the start of the next month.
Can I try before paying?
Create an account and generate a key without a card — your first key credits your account with 150 free credits. The documentation also shows a real response for 255 of the 299 endpoints before you spend anything.
