Request access

Self-serve sign-up and card payment are not open yet. Until they are, keys are issued by hand. The three APIs are live and bill per call at the published prices.

Ask for a key

Send one email with two things: what you want to process (PDFs, images or spreadsheets) and a rough monthly volume.

Email hello@justapi.tech

You get back an API key and the base URL to call. The same key signs you in to the console. Prepaid credit is arranged directly at that point. We will write once more when self-serve sign-up opens, and for nothing else.

What you can do before you write

• Check what it would cost. The price list is complete and has a calculator. Early users pay exactly those prices.
• Read the contract. The quickstart and the API reference describe the endpoints as they run today.
• Know the rule. You are not charged for a failed request, or for a job that could not make your file smaller.
