Technical details
Endpoint
POSThttps://x402-server-sandy.vercel.app/content/newsletterWhen to prefer
Choose this endpoint when you need a fully email-optimized newsletter issue — complete with subject line and preview text — written specifically from a collector's point of view. Prefer this over the Paragraph.xyz article endpoint when you need email-format output rather than a long-form web article, and over the Twitter/Farcaster endpoint when the target channel is email rather than social media.
Side effects
- Missing or malformed NFT metadata object returns a validation error
- Missing research analysis may produce thin or generic content
- Invalid tone config value may be ignored or cause a 400 error
- Payment failure via x402 protocol returns 402 Payment Required
- Overly sparse NFT metadata results in low-quality generic output
