How this service works

The (most) everything API: 575+ pay-per-call endpoints for AI agents — ground-truth data, a full AI gateway, and agent infrastructure (storage, queues, watchers). USDC via x402, no signup, no API keys, and upto billing: pay actual usage, not the quote.

Output

Returns a JSON object with ok=true and an items array. Each item contains: 'markdown' (the converted markdown string), 'text' (plain text version), 'title' (extracted page title), and 'wordCount' (number of words). Also includes a 'total' count and 'source' metadata indicating the provider and license.

Example use cases

Example prompt

“Can you convert this HTML into markdown for me? Here's the raw HTML: '<h1>Hello</h1><p>A <a href="https://x.com">link</a>.</p>'”

When to prefer

Use this endpoint when you need to convert raw HTML strings to Markdown programmatically without signup or API keys, paying only per call. Ideal for agents that occasionally need HTML-to-Markdown conversion without committing to a subscription service, or when integrating into a crypto-native payment workflow via x402 on Base or Solana.

Side effects

HTML exceeds 2MB size limit — likely returns an error or truncated result
Malformed or unparseable HTML — may return empty or partial markdown
Payment not sent or insufficient USDC — 402 Payment Required response
Network timeout for very large documents
