Technical details
Endpoint
POSThttps://stablefeedback.dev/api/namespace/feedback?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need the simplest possible feedback collection with no authentication overhead, accounts, or API keys — just pay $0.01 USDC per submission. Ideal for indie developers, quick prototypes, or any scenario where setting up a full feedback platform is overkill.
Side effects
- Invalid or missing namespace returns a 400 error
- Insufficient USDC payment causes a 402 Payment Required response
- Empty or malformed feedback body rejected with validation error
- Network timeout results in uncertain submission state — retry may create duplicate
