By category
Sell your API through Ceta
-
01
List it
Describe your API, upload its OpenAPI document and tell us the header and secret it expects. The secret is stored encrypted and never shown to anyone.
-
02
Price it yourself
Any number of plans: free, monthly or annual with included calls and a price per 1,000 extra calls, or pure pay per call. Ceta never sets your prices.
-
03
Get paid
Subscribers pay through Malaleem; Ceta's gateway checks keys, quotas and rates, meters every call and keeps its commission from your share.
Pricing
Reading the docs and the catalogue is free. Keys, the console and subscribing to APIs need a Ceta Traders membership and the Developers app (14 days free), from any country. Selling an API is for companies founded in the EU or Canada.

Questions
Who can sell or buy APIs here?
Selling an API is for companies founded in the European Union or Canada. Buying — subscribing to APIs, API keys, the sandbox and Ceta's own API — is open to companies from any country. Both need a Ceta Traders membership and the Developers app. Anybody can read the catalogue and the documentation.
Who sets the prices?
The provider alone: its own plans, monthly or annual prices, included calls and the price of extra calls. Ceta never changes them. A price change reaches existing subscribers at their next renewal, after a notice.
What does Ceta take?
The API marketplace commission, set by Ceta and shown on the pricing page. It is included in the provider's price: the subscriber pays the price shown, Ceta deducts its share from the provider's.
How are calls billed?
Monthly or annual plans renew automatically through your company's own Malaleem account; calls beyond the plan are billed at the period end; cancel any time to stop at the end of the paid period. No refunds.
Where does my key go?
Your Ceta key reaches the API through Ceta's gateway (/gw/<api>/…). The provider's own secret is added by Ceta and never shown to you; your key is never sent to the provider.
