How this service works
Bulk web search — run up to 5 search queries in one paid call and get ranked results per query (title, URL, snippet, relevance score) as clean JSON. Same news, finance, date-range, country and domain filters as single web search, applied to every query. One payment instead of five for research fan-out, multi-query RAG retrieval and agent planning.
Output
A JSON object containing a 'searches' array with one entry per submitted query (in submission order), each holding the query string and an array of results. Each result includes title, URL, content snippet, and a numerical relevance score. A 'queried_at' ISO datetime is included, plus an optional 'failed_queries' array listing any queries that failed upstream.
Example use cases
Multi-topic market research in one shot
“I need web search results for three competitor topics at once: 'OpenAI GPT-4o pricing', 'Anthropic Claude 3.5 pricing', and 'Google Gemini API pricing' — pull ranked results for all three in a single call.”
Multi-query RAG retrieval for knowledge base
“For my RAG pipeline, search for these four queries simultaneously and return the top results for each: 'how to chunk documents for embeddings', 'best embedding models for semantic search', 'FAISS vs Pinecone performance', and 'hybrid search BM25 plus dense retrieval'.”
News fan-out for agent planning
“Search the web for the latest news on five topics at the same time: 'Fed interest rate decision', 'US inflation data', 'S&P 500 outlook', 'tech sector layoffs 2025', and 'dollar index today' — I want ranked results for each query.”
Technical details
Endpoint
GEThttps://websearch.use.x402atlas.com/search/bulk?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to run 2–5 distinct web searches as part of a single agent workflow step — such as research fan-out, multi-query RAG retrieval, or parallel topic comparison — and want to pay once instead of making multiple separate calls. It is more cost-efficient and faster than chaining individual search calls when the queries are independent. Prefer the single-query endpoint if you only have one search to perform, or the deep research endpoint if you need higher-depth crawling per query.
Side effects
- Upstream search failure for one or more queries — those queries appear in 'failed_queries' array while successful ones are returned normally
- Empty results array for a query if no relevant pages were found
- Payment not processed — x402 payment required before results are returned
- Query string exceeds 1000 characters — validation error
- More than 5 queries submitted — exceeds the per-call limit
- Rate limiting or upstream provider downtime causing all queries to fail
