How this service works
Read public webpages, extract structured data and verify DOI citations. No buyer API key or subscription. Pay per call with x402 USDC on Base.
Output
Returns a JSON object containing a list of pages with their extracted structured content, a count of successfully fetched pages, the service name, and a unique requestId for tracking. Each page entry includes the parsed data from the fetched URL.
Example use cases
Academic citation fact-checking
“I have a list of DOI citations from a research paper I'm reviewing — can you batch-fetch and verify all five of them to confirm they resolve to real published articles? The DOIs are 10.1038/s41586-021-03819-2, 10.1126/science.abc1234, 10.1016/j.cell.2021.01.001, 10.1371/journal.pone.0123456, and 10.1101/2021.01.01.425001.”
Competitive content monitoring
“Pull the content from these four competitor product pages — https://competitor-a.com/pricing, https://competitor-b.com/pricing, https://competitor-c.com/features, and https://competitor-d.com/about — and give me the structured text from each so I can compare what they're saying.”
Research aggregation for a report
“I need the main content extracted from these three public reports: https://who.int/report2024, https://worldbank.org/study/poverty, and https://un.org/sustainabledevelopment/report — can you batch-read them and give me the structured data from each page?”
Technical details
Endpoint
POSThttps://evidence402.onrender.com/api/v1/web-batch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to process multiple URLs in a single call rather than making separate requests per page, especially when DOI citation verification is also needed. It is ideal for research workflows, academic fact-checking, or competitive intelligence gathering where no API key or subscription is required and pay-per-call micropayment via x402 USDC on Base is preferred over subscription models.
Side effects
- URL is not publicly accessible or behind a login wall — page returns empty or error
- DOI does not resolve to a valid publication — citation verification fails
- Rate limiting or server unavailability on target URLs — partial results returned
- x402 payment failure — call is not processed if USDC payment on Base is rejected
- Malformed or unreachable URLs in the batch — those entries return null or error status
- Target page uses heavy JavaScript rendering — content may be incomplete if only static HTML is fetched
