Technical details
Endpoint
POSThttps://centrahub.vercel.app/api/publish?utm_source=zero.xyzWhen to prefer
Use this endpoint when a creator wants to publish original written content to the Centra platform and make it available for x402-based pay-per-access monetization. Prefer this over the AI-generate-and-publish sibling endpoint when the user already has their own content ready to submit directly.
