A tiered engine that only spends what it must
Fetch
We fetch the URL server-side with a real browser fingerprint and a strict SSRF guard. Static and server-rendered pages stop here.
Render if needed
If a page is a JavaScript shell, we escalate to a headless render — only when the content is too thin, so you never overpay.
Extract
Nav, ads, cookie banners and boilerplate are stripped. You get headings, lists, links, images and code as clean Markdown.

POST /v1/convert
Authenticate with Authorization: Bearer sk_live_…. Keys are server-side only — never ship one in a browser or app bundle.
url string required The page to convert. http(s) only.
template string optional Omit for raw Markdown. Pass an AI template (clean, summary, outline…) for LLM formatting (token-metered).
render "auto" | "never" | "always" optional JavaScript rendering. Default "auto" escalates to Tier 2 only when a page is a JS shell.
fresh boolean optional Bypass the 24h cache and refetch.
Walled gardens: YouTube routes through its official transcript API. X / Instagram / TikTok are best-effort. We never use ghost accounts or scrape behind logins.
x402 · mpp · stablecoin payments
Pay per call. No account.
Signup forms are built for humans. An agent that needs one page converted right now can't create an account, confirm an email and paste a key — so it gives up and uses something else. Call the endpoint with no credentials and you get a price instead of a rejection, quoted in both protocols at once: speak either one.

# No key at all → the API quotes a price, in two protocols

} 3 · pay and retry
Your client signs a USDC transfer — on Base for x402, on Tempo for MPP — and repeats the request with the payment attached. The conversion comes back in the same round trip — no invoice, no dashboard, no waiting on a human.
$0.01 / call
USDC on Base (x402) or Tempo (MPP). No commitment, no minimum, no card.
Settled by Stripe
The deposit address is issued by Stripe. We never hold a wallet or a private key.
Or stay on keys
Nothing changes for key holders — same quota, same plans, same 401 on a bad key.
x402 and MPP are open payment protocols that put HTTP's long-dormant 402 Payment Required status to work. Evaluating by hand instead? Grab a free key — 250 pages a month, no card.
The web, readable by your agent
LLMs read Markdown, not HTML. Point an agent, a RAG ingest job, or a research loop at any URL and get back tokens worth keeping. This spec is also available as plain Markdown at /api.md. The API is discoverable through our llms.txt, agent-skills index, and API catalog.
