Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/markdown-heading-index?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call extraction of Markdown heading structure without setting up any account or subscription. It is ideal for agents that occasionally need to parse document outlines from markdown text and want verifiable, exact-cost microtransactions via USDC on Base or Solana.
Side effects
- Empty or whitespace-only text input returns an empty headings array
- Non-markdown plain text with no heading syntax returns zero headings
- Extremely large documents may be truncated, indicated by truncated:true in the response
- Malformed or non-UTF-8 encoded input may result in parsing errors
- Payment failure via x402 protocol blocks the request before processing
