- Payment not completed — endpoint returns 402 requiring $0.05 USDC before content is served
- Invalid or non-existent slug — returns error if the article slug does not match a published piece
- Handle not found — returns error if the creator handle or wallet address is unrecognized
- Content not yet published — article may not be available if not yet released for the day
- Network timeout — slow response if upstream blog infrastructure is under load
