What It Does

ArkAPI URL to Markdown fetches a public webpage, extracts the readable article body, and converts it into clean Markdown. It is useful for agent retrieval, readable exports, search ingestion, and stripping away navigation clutter before an LLM or script consumes the content.

  • Readable title, excerpt, and Markdown in one response
  • Works on ordinary public URLs
  • Simple JSON request and response shape
  • Built for Signet testing right now

Behavior

This endpoint is priced like a utility data API and uses the same funded bearer-token model as the rest of ArkAPI.

  • Cost: 5 sats per call
  • Rejects loopback, private, and reserved SSRF targets
  • Works on public HTTP and HTTPS URLs only
  • Current deployment is Signet only

Example Request

curl -X POST https://arkapi.dev/api/url-to-markdown \ -H "Authorization: Bearer ak_your_token" \ -H "Content-Type: application/json" \ -d '{"url":"https://example.com"}' | jq

Use a funded token from the Fund page. The same request body also works from agents that consume /openapi.json.

Example Body

{ "url": "https://example.com" }

Input notes

  • The URL must be public and use http or https
  • Loopback, private, link-local, and metadata addresses are rejected

Example Response
