How this service works
Wallet-native x402 APIs for web extraction, claim verification, and citation auditing.
Output
A JSON object containing the source URL, a SHA-256 hash of the page content, retrieval timestamp, document title, full-page markdown, page description, word/byte/link counts, and a list of citations found on the page.
Example use cases
Fact-check a news article claim
“I saw a claim on this page — https://techcrunch.com/2024/01/15/some-article — can you pull the full text so I can verify what it actually says?”
Summarize a competitor blog post
“Grab the content of https://competitor.com/blog/product-update and convert it to clean markdown so I can summarize what they announced.”
Audit a source URL for citations
“I need to check what citations appear on https://research.example.org/findings — can you fetch the page and list any linked sources?”
Technical details
Endpoint
GEThttps://sourcemint-api.nap6281.chatgpt.site/api/extractWhen to prefer
Choose this endpoint when an agent needs to read and process the content of a specific public web page — especially when a cryptographic hash, retrieval timestamp, or citation list is needed for provenance, auditing, or claim verification purposes. It is preferable over generic scraping tools when your workflow requires structured Markdown output and evidence-grade metadata in a single call.
Side effects
- URL is unreachable or returns non-2xx HTTP status
- URL points to non-HTML content (PDF, image, etc.) and cannot be parsed
- Page is behind a login or paywall and returns empty or redirected content
- Malformed or missing 'url' parameter returns a 400-level error
- Payment not fulfilled via x402 protocol results in 402 response
