How this service works
40 pay-per-request AI, search, headless browser, crypto alpha & memory APIs for autonomous agents settling in USDC on Base via x402 v2.
Output
A JSON object with a 'status' field ('success' or error), an 'endpoint' field, and a 'data' object containing the 'action' performed and 'content' — which is the rendered markdown string, base64-encoded screenshot/PDF bytes, array of links, DOM snapshot, or structured JSON depending on the action requested.
Example use cases
Article content extraction for research
“Fetch https://techcrunch.com/2024/06/01/some-ai-story/ in a headless browser and return the main article text as markdown so I can summarize it.”
Structured data scraping with AI prompt
“Go to https://news.ycombinator.com and extract the top 10 post titles and their scores as JSON — use this prompt: 'return an array of {title, score} objects for the top 10 stories'.”
Full-page screenshot for visual QA
“Take a screenshot of https://staging.myapp.com/dashboard so I can see what it looks like right now.”
Technical details
Endpoint
POSThttps://api.molcloud.net/api/browser/render?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to render JavaScript-heavy or dynamic pages that plain HTTP fetching can't handle, or when you need multiple output formats (PDF, screenshot, structured JSON via prompt) from the same browser session. It's ideal for autonomous agents that need to read web content without a browser environment, and it settles micropayments per-call in USDC on Base via x402 — no subscription required.
Side effects
- Target URL is unreachable or returns an HTTP error — browser render fails with error status
- JavaScript-heavy SPA may time out if it takes too long to hydrate
- screenshot/PDF actions may fail for pages with strict X-Frame or CSP policies
- json action with a vague prompt may return poorly structured or empty extraction
- Invalid enum value for 'action' field returns a validation error
