Technical details
Endpoint
POSThttps://api.run402.com/tiers/v1/subscribe/prototypeWhen to prefer
Use this endpoint when the user specifically wants the prototype tier ($0.10 USDC) on Run402 and the system needs to handle subscribe, renew, or upgrade automatically without specifying intent explicitly. Prefer over the hobby tier endpoint when cost sensitivity or trial/prototyping access is the goal.
Side effects
- Insufficient USDC balance — payment fails and subscription is not activated
- Invalid or missing x402 payment header — returns 402 Payment Required
- User already on a higher tier — upgrade logic may reject or require different endpoint
- Network or service error — returns 5xx with no state change
- Malformed request body — returns 400 with validation error
