Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-sector-writing-newsletter-heading-audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic, rule-based audit of heading hierarchy specifically within newsletter content. It is ideal for pre-send quality checks, template validation, or accessibility reviews where you need consistent structural feedback without generative AI prose or hallucination risk. Prefer this over general-purpose writing assistants when you want repeatable, bounded output on heading structure alone.
Side effects
- Input text exceeds 20,000 character limit — request rejected
- Empty or missing text field — no content to audit
- Plain text with no recognizable heading markers — limited or empty audit output
- Malformed Markdown syntax may reduce heading detection accuracy
- Payment of 0.01 USDC not fulfilled — 402 response blocking access
