Side effects
- Article not found if slug is incorrect or unpublished — likely a 404 or error response
- Payment failure if 0.1 USDC is not available or x402 payment protocol is not supported by the caller
- Handle or wallet address not recognized — creator may be unclaimed or address may be malformed
- Slug 'latest' used with a handle instead of a wallet address — not payable and may not resolve correctly
- Network or upstream database disconnect causing incomplete or empty response
