How this service works
32 website checks and HTML-to-JSON extraction for agents. Automated USDC payments on Base. Audit API: 0.25 USDC; extraction API: 0.01 USDC.
Output
Returns a JSON object containing a `paid` boolean confirming the USDC payment was processed, and an `extraction` object with the page URL, extracted plain text, page title, and schema version (e.g. '1.0').
Example use cases
Feed webpage content to an AI pipeline
“Pull the full readable text and title from https://myblog.com/post/ai-trends into JSON so I can pass it into my summarization workflow.”
Index site content for search
“Extract the text content from https://docs.myproduct.com/getting-started so I can index it — I'm authorized to process that page.”
Monitor landing page copy changes
“Grab the current text from my landing page at https://myapp.io and return it as structured JSON so I can compare it against last week's version.”
Technical details
Endpoint
GEThttps://launchcheck-tn.oe-nonprofit.chatgpt.site/api/x402/extractWhen to prefer
Choose this endpoint when you need lightweight, cheap ($0.01 USDC) extraction of plain text and title metadata from a public webpage as structured JSON, especially in agent pipelines that require machine-readable page content without building an HTML parser. Prefer it over general scraping tools when you want a pay-per-call model with automated USDC settlement on Base and a predictable JSON schema output.
Side effects
- URL contains query strings (not supported — must be a clean URL without query parameters)
- Page is not publicly accessible or requires authentication
- authorized parameter not set to 'true' (required)
- Payment failure on Base network (USDC balance insufficient or x402 protocol error)
- Target URL is unreachable or returns a non-200 status
