How this service works
Performs an intelligent web search. Costs 1 credit per returned result.
Output
A list of web search results, each containing a URL, page title, and snippet or summary. The number of results determines credit cost (1 credit per returned result). Results may be filtered by domain and recency, and can cover multiple query angles if queryFanout is enabled.
Example use cases
Competitive intelligence research
“Search the web for recent news and announcements about OpenAI and Anthropic over the last month, expanding the query to cover different angles, and exclude results from reddit.com and twitter.com.”
Domain-restricted academic search
“Find recent papers and articles about CRISPR gene editing therapies on arxiv.org and nih.gov — use query fanout to make sure we cover different phrasings of the topic.”
Market news monitoring
“Search the web for the latest news about Tesla's stock performance and earnings, filtering for fresh results only and excluding pinterest.com and quora.com from the results.”
Technical details
Endpoint
POSThttps://x402.orthogonal.com/context-dev/web/searchWhen to prefer
Choose this endpoint when you need live web search with intelligent query expansion (fan-out) to maximize recall across different phrasings. Prefer it over generic search APIs when you want fine-grained domain control (whitelisting or blacklisting specific sites) or need to ensure freshness of results. Especially valuable for research agents that need comprehensive, multi-angle coverage of a topic from authoritative or curated domains.
Side effects
- Empty query string returns an error or zero results
- Invalid domain format in include_domains or exclude_domains may be silently ignored or cause an error
- Overly restrictive domain filters returning zero results
- Insufficient credits causing payment failure (x402 payment required)
- Freshness filter with no recent content returns few or zero results
- Query fanout may increase latency and credit consumption
