Technical details
Endpoint
POSThttps://basepost.vercel.app/api/uploadWhen to prefer
Use this endpoint when an agent needs to publish user-authored content to a decentralized, censorship-resistant news platform where the author retains monetization control via crypto micropayments on Base. Prefer over traditional CMS APIs when the user wants Web3-native publishing with USDC paywalls and no intermediary platform fees.
