# SERP Batch Search

> SERP Batch Search is a paid API for AI agents from api.kadec0.xyz, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Runs up to 5 web or news search queries in a single API call, returning ranked title, URL, and snippet per query with locale, freshness, and safesearch controls.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability serp-batch-search-a9696151
```

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.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
