Decision API is your decision AI aggregation platform. Explore Jev, Laya, Kev, Solar and Span in one playground, then connect classification, scoring and routing through a single API. Start with 100 credits.
We reserve this budget before the model runs, then charge actual usage and return the difference. Failed calls are refunded.
New account? Receive 100 credits once. Short requests typically use 1 credit; longer inputs can use more. 100 welcome credits · one balance for web & API

One Decision API integration. Multiple models.
Move from the Decision API playground to your backend with the same state and question structure. Choose a supported model, create an API key, and use the generated cURL, JavaScript, or Python example. The shared endpoint keeps your integration familiar as you explore different decision models.
Send requests to Decision API with a server-side Bearer token. Successful responses contain structured answers and usage information. Check the response status, keep the request identifier for troubleshooting, and handle errors explicitly. Your application decides whether the result should route a ticket, request a review, or trigger the next operation.
Decision API uses one balance for playground, API, and evaluation calls at the same per-model rates. A budget is reserved before each call; successful calls settle actual input usage, and failed calls are refunded. Review the request and model rate before integrating.
One credit balance for web, API and evaluation. New accounts receive 100 credits.
$1 = 10,000 credits on every pack. Credits do not expire. Pay once, with no subscription. Successful calls start at 1 credit; actual input usage determines the charge. Site input rates per million tokens: Jev / Kev $0.06, Solar Decide $0.072, Span-01 $0.03, and Laya $0.06. Output tokens are not charged. Starter
