How this service works
VALUNARIA BUS-WEB web.extract.v1
Output
A JSON object containing: the extracted main text body, page title, description, canonical and resolved URLs, list of links, content type, HTTP status code, a SHA256 hash of the content, the observed timestamp, any additional metadata, and a unique request ID for the call.
Example use cases
Article summarization from URL
“Grab the main article text from https://www.bbc.com/news/world-us-canada-68000001 so I can summarize the key points for my newsletter.”
Competitor product page monitoring
“Fetch the content of https://competitor.com/pricing right now so I can see if they've updated their pricing tiers since last week.”
Research source verification
“Extract the text from https://arxiv.org/abs/2401.00001 so I can check whether it actually supports the claim I'm about to cite in my report.”
Technical details
Endpoint
POSThttps://x402.valunaria.com/api/v1/web/extract?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need machine-readable extraction of a single public web page's text and metadata with per-call micropayment billing via x402 on Base/USDC — ideal for AI agents that need pay-as-you-go web reading without subscription overhead. Prefer this over general browser automation when you only need structured text and link extraction from a known URL, not full JavaScript rendering or interactive browsing.
Side effects
- URL is not publicly accessible (returns error or non-2xx HTTP status)
- Target page blocks bots or requires authentication (content may be empty or partial)
- URL resolves to non-HTML content such as PDF or binary file (content_type may differ from text/html)
- Network timeout or unreachable host (request fails)
- Malformed or invalid URL input (validation error returned)
- Payment failure over x402 (402 response if USDC balance insufficient)
