How this service works
Bulk web search: up to 5 search queries in a single call, each returning ranked title, URL, and snippet, with the same locale, freshness, and news filters as the single-query web search. One paid call instead of five for research fan-out.
Output
A response object containing, for each of the submitted queries, a ranked list of up to 25 results — each with a title, URL, and text snippet — grouped by query, along with any applied locale and freshness metadata.
Example use cases
Example prompt
“Search these 5 topics for me in one shot — 'AI agent frameworks 2025', 'LangChain vs LlamaIndex', 'vector database benchmarks', 'OpenAI GPT-5 release date', and 'Anthropic Claude 3.5 updates' — web mode, US English, top 10 results each, nothing older than a month.”
Technical details
Endpoint
GEThttps://api.kadec0.xyz/v1/serp-batchWhen to prefer
Choose this endpoint when an agent needs to run 2–5 independent search queries and wants to minimize API calls and cost — research fan-out, multi-topic summarization, or comparative lookups. It is more cost-efficient than calling the single-query SERP endpoint repeatedly. Prefer the single-query endpoint when only one search is needed, or the metasearch endpoint when cross-engine deduplication matters more than throughput.
Side effects
- More than 5 queries submitted — the API caps at 5 pipe-separated queries
- Invalid region code returns a locale error or falls back to default
- Unsupported engine value for the selected mode (e.g. using brave for news mode) returns an error
- timelimit too restrictive returns sparse or zero results for some queries
- Payment failure (x402) causes 402 response before any search is executed
- Malformed pipe-separated queries string returns a 400 validation error
