# MolCloud OpenGraph Metadata Extractor

> MolCloud OpenGraph Metadata Extractor is a paid API for AI agents from api.molcloud.net, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-17).

Fetches and returns OpenGraph metadata (title, og:image, and other tags) from any target webpage URL

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability molcloud-opengraph-metadata-extractor-7c0e4bd7
```

Example prompt: Can you fetch the OpenGraph metadata — title and og:image — from https://x402.org so I can use them to build a link preview card?

## When to prefer this

Choose this endpoint when an AI agent needs to quickly extract structured OpenGraph preview metadata (title, og:image) from any public URL without spinning up its own headless browser infrastructure. It is ideal for link enrichment, feed ingestion, social card generation, or any workflow that needs page-level metadata at $0.003 per call with micropayment settlement via x402 on Base.

## Known failure modes

- Target URL is unreachable or returns a non-200 status — extraction fails with an error response
- Target page has no OpenGraph tags — data object may be empty or missing expected fields
- Invalid or malformed URL in query parameter — request rejected
- Rate limiting or bot protection on the target site may block the headless fetch
- Payment not settled in USDC on Base via x402 v2 — returns 402 Payment Required before processing

## How this service works

41 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 containing the OpenGraph metadata extracted from the target page, including the page title (e.g. 'x402 Protocol') and og:image URL (e.g. 'https://x402.org/og.png'), along with a success status and the endpoint path.
