How this service works
Search multiple live web sources and return structured factual claims with supporting evidence and source URLs.
Output
A JSON object containing an array of facts, an array of sources with citations, an array of conflicts between sources, an array of agreements across sources, a confidence score (0–1) indicating overall evidence reliability, usage metrics, and economics data about the query.
Example use cases
Fact-checking a contested claim
“Can you search for evidence on whether intermittent fasting actually extends lifespan in humans? I want to see the key facts, any conflicting studies, and how confident the findings are.”
Research briefing on emerging topic
“Search for evidence on the economic impact of AI automation on manufacturing jobs — pull together the main facts, sources, and note where experts seem to disagree.”
Verifying a statistic before publishing
“Before I publish this piece, can you find evidence supporting or contradicting the claim that 'over 80% of ocean plastic comes from 10 rivers'? I need the sources and a confidence level.”
Technical details
Endpoint
POSThttps://relay.straelo.com/search-evidence?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, sourced evidence with explicit conflict and agreement detection and a machine-readable confidence score — rather than a raw web search or unstructured document retrieval. It is especially useful for fact-checking, research synthesis, or pre-publication verification where knowing the reliability and consensus of evidence matters as much as the facts themselves.
Side effects
- Empty facts array returned if no evidence found for the query
- Low confidence score (near 0) when evidence is sparse or contradictory
- Payment failure if USDC balance is insufficient for the $0.03 per-call fee
- Query too short or empty triggers validation error (minLength:1 required)
- Sources array may be empty for highly niche or novel topics with no indexed evidence
- Conflicts array may surface when sources fundamentally disagree, requiring human judgment
